What Does a Wheel Hub Stud Do?

Each wheel stud passes through the hub and provides a strong threaded fixing for the wheel nut.

When the wheel nuts are correctly tightened, the studs provide the clamping force required to securely hold the wheel against the hub.

A correctly functioning wheel stud helps:

• Secure the wheel to the hub
• Provide the mounting thread for the wheel nut
• Maintain correct wheel clamping force
• Allow safe wheel installation and removal
• Keep the wheel correctly seated against the hub

Why Do Wheel Hub Studs Fail?

Wheel studs are strong components but can become damaged through repeated wheel removal, incorrect tightening or corrosion.

Common causes include:

• Damaged or stripped threads
• Cross-threaded wheel nuts
• Excessive wheel nut torque
• Corrosion Impact damage
• Incorrect wheel installation
• Repeated use of unsuitable tools
• General wear from frequent wheel changes

Using an impact wrench incorrectly or overtightening wheel nuts can stretch or damage the stud and its threads.

When Should a Wheel Stud Be Replaced?

Replacement should be considered if:

• Threads are stripped or damaged
• A wheel nut will not tighten correctly
• The stud is bent or distorted
• Heavy corrosion is present
• The stud has been cross-threaded
• A stud has broken
• The stud is loose within the hub
• Damage is discovered during wheel or brake servicing

A damaged wheel stud should not be reused, as correct wheel clamping depends on the condition of both the stud and wheel nut.

Important Wheel Mounting Checks

When replacing a wheel stud, inspect the wheel nut and hub for corresponding damage.

Wheel nuts should thread smoothly onto the studs by hand before final tightening. Always tighten wheel nuts to the correct specified torque.

If several studs show similar corrosion or thread damage, inspect the remaining studs and consider replacing any that are no longer serviceable.

Wheel Studs

Wheel studs are an essential part of the wheel and hub assembly on many classic and modern-classic Porsche models.

Although designed for long service life, repeated wheel removal, corrosion, cross-threading and excessive tightening can eventually damage the threads or weaken the stud.

When carrying out wheel, brake or hub maintenance, each stud should be inspected for damaged threads, corrosion or distortion. Replacing defective studs helps ensure the wheel can be correctly and securely mounted.

• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1975-1977 3.0L Turbo (930)

What Does the Handbrake Cover Do?

The handbrake cover is primarily an interior trim and protective component. It surrounds the handbrake lever and heating control area while concealing the mechanical components beneath.

A correctly fitted cover helps:

• Provide a neat factory-style appearance
• Cover the handbrake mechanism
• Accommodate the manual heating controls
• Protect components from dirt and debris
• Finish the centre tunnel area
• Improve the appearance of a restored interior

This version is specifically intended for cars equipped with manual heating controls.

Why Do Handbrake Covers Fail?

Unlike a mechanical component, the handbrake cover does not normally fail through operation. Instead, deterioration occurs through age, repeated use and general interior wear.

Common problems include:

• Cracking or splitting with age
• Surface wear and deterioration
• Damage around mounting points
• Distortion or warping
• Previous incorrect removal or installation
• Missing or damaged original trim
• General deterioration during interior restoration

On older Porsche 911 models, original interior trim can become brittle after decades of heat and temperature changes.

When Should the Handbrake Cover Be Replaced?

Replacement should be considered if:

• The original cover is cracked or split
• Mounting points are damaged
• The cover has become distorted
• The surface is heavily worn
• The original cover is missing
• It no longer fits securely
• The interior is undergoing restoration
• A damaged cover affects the appearance of the centre tunnel

Replacing worn trim is particularly worthwhile during a complete interior restoration where maintaining the correct period appearance is important.

Important Fitment Checks

Before ordering, confirm that the vehicle is equipped with the manual heating system, as different heating arrangements may use different handbrake covers or surrounding trim.

The handbrake lever, heating controls and mounting points should also be inspected while the cover is removed.

Porsche 911 1973-85 Handbrake Covers & Interior Trim

Interior trim is an important part of maintaining the original appearance of a classic Porsche 911.

After decades of use, handbrake covers and centre tunnel trim can become cracked, worn, distorted or damaged. Replacing deteriorated components helps restore a cleaner, more complete interior while protecting the mechanisms underneath.

For Porsche 911 models with manual heating, selecting the correct handbrake cover is important because the trim must accommodate the associated heating controls.

Crankshaft Pulley with Dampener – Porsche 958 Cayenne / 970 Panamera Hybrid 

Restore smooth and reliable engine operation with this OE Match Crankshaft Pulley with Dampener. The crankshaft pulley is mounted to the front of the crankshaft and drives the auxiliary belt system. Its integrated vibration dampener also helps absorb torsional vibrations generated by the engine, reducing stress on the crankshaft and belt-driven components.

Fits:

• Porsche 958 Cayenne S V6 3.0L Hybrid (380Hp) 2010-17
• Porsche 970.1 Panamera S Hybrid V6 3.0L 2011-13
• Porsche 970.2 Panamera S E-Hybrid V6 3.0L (416Hp) 2014-16

Diagram ref no 4

What Does the Crankshaft Pulley with Dampener Do?

As the engine runs, the crankshaft produces small twisting vibrations with each combustion cycle. The dampener helps absorb these vibrations before they are transferred through the crankshaft and auxiliary drive system.

The pulley also transfers crankshaft rotation to the auxiliary drive belt.

A correctly functioning crankshaft pulley helps:

• Drive the auxiliary belt system
• Reduce crankshaft torsional vibration
• Maintain smooth belt operation
• Reduce vibration transmitted to engine components
• Protect associated pulleys and belt-driven equipment
• Support smooth engine operation

Why Do Crankshaft Pulleys and Dampeners Fail?

The dampener is exposed to constant vibration, heat and engine speed changes. Over time, the rubber damping material between the pulley sections can deteriorate, crack or separate.

Common causes include:

• Age-related rubber deterioration
• Repeated heating and cooling cycles
• Engine vibration
• Contamination from engine oil or other fluids
• Cracking or separation of the damping material
• Pulley distortion or damage
• High mileage and general wear

Once the damping material deteriorates, the inner and outer sections of the pulley can begin moving independently.

When Should the Crankshaft Pulley Be Replaced?

Replacement should be considered if:

• The pulley visibly wobbles while the engine is running
• Cracks appear in the rubber dampening section
• The rubber begins separating from the pulley
• Unusual vibration develops from the front of the engine
• The auxiliary belt runs unevenly
• Squeaking, knocking or rattling noises are present
• The pulley is physically damaged or distorted
• Inspection confirms deterioration of the dampener

A failing crankshaft pulley should not be ignored, as complete separation can affect the auxiliary drive system and potentially damage surrounding components.

Important Auxiliary Drive Checks

When replacing the crankshaft pulley, inspect the auxiliary drive belt, tensioner, idler pulleys and surrounding components for wear or damage.

Any oil or coolant leaks contaminating the pulley should also be repaired, as fluids can accelerate deterioration of the rubber damping material.

Porsche Cayenne 958 & Panamera 970 Hybrid Crankshaft Pulleys

The crankshaft pulley and vibration dampener form an important part of the engine's auxiliary drive and vibration-control system.

As Porsche Cayenne 958 and Panamera 970 Hybrid models age, the rubber damping element can deteriorate through heat, vibration and general wear. Typical signs include pulley wobble, abnormal vibration, belt movement and noise from the auxiliary drive area.

During diagnosis, the pulley should be inspected alongside the auxiliary belt, tensioner and idler pulleys to identify any additional worn components.

Rear wheel bearing seal outer. DG 62 x 68 x 6 / 10.
OE Match rear wheel bearing outer seal engineered to replicate the original factory sealing component used on early Porsche 911 and 912 models (1965–1968). It is designed to fit into the wheel hub to seal the outer side of the rear wheel bearing, keeping lubricant in and contaminants out.
Sold per each, 2 required per car.

Fits:
Porsche 911 2.0 01/1963 - 07/1968
Porsche 912 1.6 01/1965 - 07/1968

Diagram Ref No 10

The rear wheel bearing outer seal prevents lubricant loss from the wheel hub and keeps dirt, water, and debris out of the bearing assembly. By maintaining correct lubrication and preventing contamination, the seal helps ensure smooth bearing rotation and prolongs the service life of the wheel bearings.

Function:
Installed on the outer side of the rear wheel hub, this seal:
• Retains bearing lubricant inside the hub assembly
• Keeps water, mud, dust, and road contaminants out
• Protects internal bearing surfaces from corrosion and wear
•  Maintains correct contact with the rotating bearing outer race
Accurate lip geometry and correct seal dimensions are essential to form a tight sealing interface while accommodating hub rotation and slight shaft movement.

Wheel bearing seals protect the integrity of the bearing assembly - a critical rotational component subjected to high loads, speed, and road conditions. A worn, cracked, or leaking seal can allow grease to escape and contaminants to enter, resulting in accelerated bearing wear, noise, vibration, and ultimately bearing failure. Installing fresh OE Match seals helps preserve bearing lubrication and contributes to smooth, quiet rear wheel rotation and long service life.

When to replace:
•  During wheel bearing service or rebuild
•  If seal lip is cracked, hardened, or visibly worn
•  When grease appears contaminated, leaking, or lost
•  After water exposure or road debris impact
•  As preventive maintenance on unrestored classic vehicles

What Does the Front Inner Wheel Bearing Do?

The inner wheel bearing sits within the front hub assembly and works with the outer bearing to support the rotating hub.

A correctly functioning wheel bearing helps:

• Allow smooth wheel and hub rotation
• Support vehicle and cornering loads
• Maintain correct hub alignment
• Minimise friction during wheel rotation
• Prevent excessive movement at the wheel
• Support consistent steering and handling

Why Do Wheel Bearings Fail?

Wheel bearings are subjected to continuous rotation, road impacts, heat and heavy suspension loads. Wear gradually develops with mileage and age.

Common causes include:

• Normal bearing wear
• Incorrect bearing adjustment
• Insufficient or contaminated grease
• Water and dirt contamination
• Damaged bearing seals
• Corrosion
• Heavy impacts from potholes or kerbs
• Incorrect installation or overtightening

Poor lubrication or incorrect adjustment can considerably shorten bearing life.

When Should the Front Wheel Bearing Be Replaced?

Replacement should be considered if:

• A humming, rumbling or grinding noise is present
• Noise increases with road speed
• Excessive play is detected at the front wheel
• The bearing feels rough when rotated
• Steering or wheel stability becomes inconsistent
• The bearing shows corrosion or surface damage
• Inspection reveals worn rollers or bearing races

Wheel bearing noise can sometimes be confused with tyre or suspension noise, so inspection is recommended before replacement.

Important Front Hub Checks

When replacing the inner wheel bearing, the complete front hub assembly should be inspected.

Check the outer wheel bearing, bearing races, seals, spindle and hub for wear or damage. Bearings should be correctly lubricated and adjusted during installation.

If the mating bearing race is worn, scored or damaged, it should also be replaced rather than fitting a new bearing against a damaged surface.

Porsche 944, 928 & 968 Front Wheel Bearings

Front wheel bearings are essential components of the Porsche 944, 928 and 968 suspension and hub assemblies, allowing the wheels to rotate smoothly while supporting substantial vehicle and cornering loads.

As these models age, bearing wear, deteriorated grease and contamination can cause increased noise, roughness or excessive wheel movement.

When servicing Porsche front wheel bearings, the inner and outer bearings, races, seals and hub should all be inspected to ensure the complete assembly remains in good condition.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Diagram ref no 1

What Does the Auxiliary Support Cross Tube Do?

The auxiliary support cross tube is mounted across the front underside of the vehicle and forms an important structural part of the suspension system.

Its functions include:

• Supporting front suspension components
• Providing secure suspension mounting points
• Helping maintain correct suspension geometry
• Maintaining structural rigidity across the front suspension
• Supporting accurate steering and suspension operation

Because suspension loads are transferred through this area, the condition and alignment of the cross tube are important for correct handling.

Why Do Auxiliary Support Cross Tubes Fail?

Unlike a normal service component, the cross tube does not have a scheduled replacement interval. Damage is generally caused by age, corrosion, accident damage or previous repairs.

Common problems include:

• Corrosion and rust
• Damage around mounting points
• Distortion caused by accident impact
• Cracks or metal fatigue
• Damage from incorrect jacking or lifting
• Worn or enlarged mounting holes
• Previous poor-quality repairs
• General deterioration on older vehicles

Corrosion is particularly important on early Porsche 911 models, where decades of exposure to moisture and road contamination can weaken suspension mounting areas.

When Should the Cross Tube Be Replaced?

Replacement should be considered if:

• Significant corrosion is present
• Suspension mounting points are damaged
• The cross tube is bent or distorted
• Cracks or structural damage are found
• Suspension geometry cannot be correctly adjusted
• Accident damage has affected the front suspension
• Previous repairs have compromised its strength
• The component is unsuitable for reuse during restoration

Any suspected structural damage should be carefully inspected before the vehicle is returned to the road.

Important Front Suspension Checks

When replacing the auxiliary support cross tube, the surrounding suspension and mounting areas should also be inspected.

Check the spring struts, suspension arms, bushes, ball joints, steering components, mounting hardware and body attachment points for wear, corrosion or damage.

A wheel alignment should be carried out where necessary after suspension components have been replaced or disturbed.

Porsche 911 1969-71 Front Suspension Cross Tubes

Early Porsche 911 suspension components are now several decades old, making corrosion, previous accident damage and general deterioration increasingly common.

The auxiliary support cross tube is an important part of the front suspension structure. Damage or corrosion can affect suspension mounting, alignment and overall front suspension integrity.

During restoration of a 1969, 1970 or 1971 Porsche 911, the cross tube and surrounding suspension mounting areas should be carefully inspected, particularly where corrosion or previous repairs are visible.

Dashboard complete with front air vent hole for LHD cars. Black.
The OE MATCH Complete Dashboard with Front Air Vent Hole is a replacement dashboard designed for compatible left-hand-drive (LHD) Porsche applications. Finished in black, it provides a solution for restoring an interior where the original dashboard has become cracked, warped, faded or otherwise damaged through age and exposure.

Fits:

• Porsche 911 1986 3.2L
• Porsche 911 1987-1989 3.2L G50
• Porsche 911 1978-1989 3.3L Turbo (930)

The dashboard is one of the most visually prominent parts of a classic Porsche interior. Years of sunlight, heat and temperature changes can cause the original material to deteriorate, particularly around the windscreen, instrument area and ventilation openings.

This replacement dashboard is supplied with the front air vent hole configuration and is intended for LHD vehicles where this dashboard specification is required.

What This Product Does:
The dashboard forms the main upper structure and finished surface of the vehicle's front cabin.

As well as defining the appearance of the interior, it provides the surrounding structure and mounting environment for various dashboard components and controls.

Depending on the vehicle specification, these can include:

• Instrument cluster and gauges
• Air ventsSwitchgear
  
• Heating and ventilation controls
• Trim components
• Associated dashboard fittings

The dashboard also creates the finished transition between the cabin, windscreen area and vehicle controls.

A dashboard in good condition therefore contributes to both interior functionality and the overall appearance of the vehicle.

Symptoms Of Wear Or Failure:
Dashboard deterioration is usually visually obvious.

Common signs include:

• Cracks across the dashboard surface
• Splitting around air vents
• Cracks around the instrument area
• Damage near the windscreen edge
• Warped or distorted dashboard sections
• Shrinkage of the covering material
• Raised or uneven surfaces
• Faded or discoloured finish
• Loose or separating trim
• Damaged mounting areas
• Previous repairs becoming visible
• Poorly fitting dashboard components
• Cuts, holes or other physical damage

Small cracks can gradually spread as the dashboard continues to experience temperature changes.

Why Replacement Matters:
A deteriorated dashboard does not normally affect the basic mechanical operation of the vehicle, but it can have a major impact on the quality and appearance of the interior.

Replacing a badly cracked or damaged dashboard helps:

• Restore the appearance of the cabin
• Eliminate prominent cracks and splits
• Improve the fit of dashboard trim and components
• Restore a clean surface around instruments and vents
• Improve the quality of an interior restoration
• Replace previous poor-quality dashboard repairs
• Maintain the presentation of a classic Porsche
• Provide a fresh foundation for surrounding interior components

For restoration projects, the dashboard is particularly important because it occupies such a large and highly visible area of the cabin.

Why Replace It ?

A servo motor should be replaced if it fails to operate or communicate properly, or if it shows signs of electrical damage or corrosion. Common symptoms include:AWD warning lights in the instrument clusterVehicle operating as 2WD instead of AWDSlow, noisy, or delayed engagementClunks or unusual noises when slowing downStored transfer-case diagnostic trouble codes (DTCs)Because the motor contains sensors (potentiometers) and the connector seals can deteriorate, many failures are electrical rather than purely mechanical. 

 Common Symptoms & Failure Signs of AWD Systems

• Dashboard Warnings: Messages like “All-wheel drive system defective” may appear, often accompanied by reduced or no AWD functionality.
• AWD Engagement Issues: Vehicle stuck in 2WD or transfer case fails to shift into longitudinal reduction.
• Drivetrain Noises: Clunks, slow engagement, or unusual sounds at low speeds, sometimes intermittent.
• Diagnostic Trouble Codes (DTCs)
• Common codes related to AWD/transfer case issues include:
• 2040: Voltage supply to transfer box servo motor
• 2041: Ground supply
• 2042: Activation
• 2039 / 2033: Other transfer case errors
• These codes typically prompt technicians to inspect the servo motor, wiring, and connector pins.
• Connector Corrosion & Moisture Issues
• Porsche technical bulletins note that the servo motor plug can allow moisture ingress, leading to corroded pins. Recommended solutions include:
• Repair kit (replacing a section of cable/plug)
• Full replacement of motor + cable, depending on damage
• Tip: Don’t assume the motor is faulty before checking connectors and wiring.
• Transfer Case Mechanical Wear
• Sometimes, noisy or slipping transfer cases are due to mechanical issues rather than the servo motor. Common problems include:
• Stretched chain
• Worn internal components
• These failures are especially common on higher-mileage Porsche 955/957 models. Always consider mechanical wear as a potential cause when diagnosing AWD problems.
• When replacing you will need a new ECU module to fit or reprogrammed

Diagram ref no 6

What Does the Thermostat Insert Do?

When the engine is cold, the thermostat remains closed to restrict coolant flow through the radiator, helping the engine warm up efficiently.

As coolant temperature rises, the thermostat opens and allows coolant to circulate through the radiator where excess heat can be removed.

A correctly operating thermostat helps:

• Maintain the correct engine temperature
• Allow faster engine warm-up
• Regulate coolant flow through the radiator
• Prevent excessive engine temperatures
• Support efficient engine operation
• Maintain consistent cooling system performance

Why Do Thermostats Fail?

Thermostats operate through thousands of heating and cooling cycles and can gradually deteriorate with age.

Common causes include:

• Internal mechanical wear
• Thermostat valve sticking
• Weakening of the temperature-sensitive element
• Coolant contamination or deposits
• Corrosion within the cooling system
• Overheating General age-related deterioration

A thermostat can fail either open or closed. A thermostat stuck open can cause the engine to run too cool, while one stuck closed can restrict coolant circulation and cause overheating.

When Should the Thermostat Be Replaced?

Replacement should be considered if:

• The engine takes unusually long to warm up
• Engine temperature remains below normal
• Engine temperature becomes too high
• Temperature readings fluctuate unexpectedly
• Cabin heater performance is poor
• Diagnostic testing indicates incorrect coolant temperature
• The thermostat is sticking or no longer opening correctly
• Cooling system repairs make replacement advisable

Thermostat replacement is also commonly considered during major cooling system maintenance, particularly on higher-mileage vehicles.

Important Cooling System Checks

Overheating or incorrect engine temperature is not always caused by the thermostat.

The coolant level, water pump, radiator, cooling fans, hoses and cooling system should also be inspected when diagnosing temperature problems.

Any coolant leaks should be repaired and the cooling system correctly filled and bled after thermostat replacement.

Porsche Cayenne, Macan & Panamera Thermostats

The thermostat is a key component of the Porsche engine cooling system, controlling coolant circulation according to engine temperature.

As Cayenne, Macan and Panamera models age, thermostats can become slow to operate or stick partially open or closed. Typical symptoms include slow engine warm-up, low operating temperature, fluctuating temperature readings or overheating.

When diagnosing Porsche cooling system problems, the thermostat should be checked alongside the water pump, radiator, coolant level and other cooling system components.

What Does the Air Suspension Compressor Do?

The compressor is the main source of air pressure for the Cayenne air suspension system. It draws in and compresses air before supplying it to the suspension system, where it is used to inflate the air springs.

A correctly functioning compressor helps:

• Maintain the correct vehicle ride height
• Raise and lower the suspension
• Supply pressure to the air suspension system
• Compensate for changes in vehicle load
• Maintain correct suspension operation

Why Do Air Suspension Compressors Fail?

Air suspension compressors naturally wear over time, particularly if they are required to run more frequently than normal.

Common causes include:

• Internal compressor wear
• Overheating from excessive operation
• Worn piston seals
• Moisture or contamination
• Electrical motor failure
• Damaged wiring or connections
• Air leaks elsewhere in the suspension system
• General age-related deterioration

An air leak can cause the compressor to run excessively as it repeatedly attempts to restore system pressure. This can eventually overheat and damage an otherwise serviceable compressor.

When Should the Air Suspension Compressor Be Replaced?

Replacement should be considered if:

• The vehicle is slow to raise
• The suspension does not reach the selected height
• The compressor runs excessively
• The compressor becomes unusually noisy
• Air suspension warning messages appear
• The vehicle remains too low
• Diagnostic testing identifies insufficient compressor pressure
• The compressor motor no longer operates

Before fitting a replacement compressor, the complete air suspension system should be checked for leaks. Installing a new compressor without correcting an existing leak can cause the replacement unit to fail prematurely.

Important Air Suspension Checks

If the Cayenne drops in height while parked, the compressor may not necessarily be the cause.

Air springs, air lines, valve blocks and connections should be inspected for leaks. The compressor relay, fuse and electrical supply should also be checked when diagnosing a non-operating compressor.

Porsche Cayenne 955 & 957 Air Suspension Compressors

The air suspension system fitted to Porsche Cayenne 955 and 957 models provides automatic ride-height control and allows the suspension height to be adjusted according to driving conditions.

As these vehicles age, compressors, air springs, valve blocks and air lines can deteriorate. A weak compressor may struggle to produce sufficient pressure, resulting in slow suspension operation, incorrect ride height or suspension warning messages.

When diagnosing Porsche Cayenne air suspension problems, checking the complete system for leaks is particularly important. A leaking air spring or connection can make the compressor work continuously and significantly shorten its service life.

Diagram Ref No 1

What Does the Throttle Body Do?

The throttle body contains a circular butterfly valve that opens and closes to regulate airflow into the engine.

When the accelerator is pressed, the engine management system electronically controls the throttle body, opening the valve to increase airflow and closing it when less engine power is required.

A correctly functioning throttle body helps:

• Control engine intake airflow
• Maintain a smooth, stable idle
• Provide responsive acceleration
• Maintain consistent engine performance
• Support accurate engine management

Why Do Throttle Bodies Fail?

Throttle bodies are exposed to heat, vibration and contamination throughout their working life. Oil vapour and carbon deposits can accumulate around the throttle plate, while the electronic actuator and internal position sensors can deteriorate with age.

Common causes include:

• Carbon and oil deposits
• Electronic actuator wear
• Throttle position sensor faults
• Electrical motor failure
• Damaged wiring or connectors
• Heat and vibration
• General age-related deterioration

A contaminated throttle body may sometimes be cleaned successfully, providing its electronic components remain serviceable.

When Should the Throttle Body Be Replaced?

Replacement should be considered if:

• Idle becomes unstable or fluctuates
• Throttle response becomes slow or inconsistent
• The engine hesitates during acceleration
• The vehicle enters limp-home mode
• Throttle-related fault codes are stored
• Cleaning does not restore correct operation
• Diagnostic testing identifies an internal fault
• The throttle plate sticks or fails to operate correctly

Similar symptoms can be caused by intake leaks, wiring or other engine management components, so correct diagnosis is recommended before replacement.

Electronic throttle bodies play an important role in Porsche engine management and intake systems.

As Porsche models age, contamination, actuator wear and electronic faults can lead to poor throttle response, unstable idle, hesitation and engine management warnings.

When diagnosing a Porsche throttle body fault, the intake pipework, electrical connections and associated engine management components should also be checked before replacement.

Diagram ref no 4

When the control mechanism develops a fault, the suspension may become slow to adjust, sit unevenly or fail to maintain the selected ride height.

What Does the Air Suspension Control Mechanism Do?

The Porsche Cayenne air suspension uses compressed air rather than conventional steel springs to support the vehicle and alter its ride height.

The control mechanism manages the flow of compressed air within the system, allowing air to be directed to or released from the appropriate suspension circuits as required.

This allows the air suspension system to:

• Raise and lower the vehicle
• Maintain the required ride height
• Compensate for changes in vehicle load
• Control air distribution within the suspension
• Maintain balanced suspension operation
• Respond to commands from the air suspension control system

The supplied support provides the correct mounting arrangement for the control mechanism.

Why Do Air Suspension Control Mechanisms Fail?

Air suspension components operate under pressure and are exposed to moisture, road contamination, vibration and repeated operating cycles.

Over time, internal valves and seals can deteriorate or become contaminated, preventing the mechanism from controlling airflow correctly.

Common causes of failure include:

• Internal valve wear
• Deteriorated seals
• Moisture entering the air suspension system
• Dirt and contamination
• Internal air leakage
• Corrosion
• Repeated pressure cycles
• Age and mileage
• Electrical faults within the control mechanism

A failing air suspension compressor or leaking air spring can also place additional demand on other parts of the system, so the complete air suspension should be checked when diagnosing a fault.

Symptoms of a Faulty Air Suspension Control Mechanism

Problems with the control mechanism can produce a number of different suspension symptoms, including:

• Vehicle sitting unevenly
• One or more corners at the incorrect height
• Suspension slow to raise or lower
• Vehicle failing to reach the selected ride height
• Suspension dropping after the vehicle is parked
• Air suspension warning messages
• Excessive compressor operation
• Inconsistent ride height adjustment

These symptoms can also be caused by leaking air springs, damaged air lines, height sensors, compressor problems or other system faults. Correct diagnosis is therefore recommended before replacing the control mechanism.

When Should It Be Replaced?

Replacement should be considered when the control mechanism has been diagnosed as faulty or when physical deterioration prevents reliable operation.

This may include situations where:

• Internal valves are sticking or leaking
• The mechanism cannot correctly distribute air
• The vehicle repeatedly develops uneven ride height
• Diagnostic testing identifies a control mechanism fault
• Corrosion or physical damage is present
• Air suspension operation has become unreliable
• The unit has been damaged during previous suspension repairs

Unlike conventional service items, the air suspension control mechanism does not have a fixed replacement interval. It should normally be replaced when testing confirms failure or deterioration.

Check the Complete Air Suspension System

Air suspension faults can have several possible causes, so replacing individual components without diagnosis can result in unnecessary repairs.

When investigating a Porsche 958 Cayenne air suspension problem, it is worthwhile checking:

• Air suspension compressor
• Air springs
• Air lines and connections
• Ride height sensors
• Pressure system
• Electrical connectors and wiring
• Associated suspension control components

Air leaks are particularly important to identify because a leaking system can cause the compressor to operate more frequently, potentially shortening its service life.

Porsche 958 Cayenne Air Suspension Control & Repair Components

The air suspension system fitted to the Porsche 958 Cayenne combines adjustable ride height with automatic load compensation and controlled suspension operation.

Unlike a conventional steel spring suspension, the system relies on several interconnected pneumatic and electronic components. The compressor generates compressed air, while the control system distributes it to the air springs according to the required vehicle height and operating conditions.

As these vehicles age, air leaks, worn valves, compressor problems and sensor faults can cause incorrect ride height or air suspension warning messages.

Correct diagnosis is particularly important. A Cayenne sitting low on one corner, for example, does not automatically mean the air spring itself has failed. The problem may also be associated with air distribution, pipework, sensors or another part of the control system.

Replacing a faulty air suspension control mechanism with the correct OE Match component helps restore controlled air distribution and reliable ride height operation.

Diagram ref no 12

A faulty sensor can cause incorrect low-coolant warnings or may fail to report a genuine drop in coolant level. Replacing a defective sensor restores an important part of the cooling system's monitoring and warning function.

What Does the Coolant Bottle Level Sensor Do?

The coolant level sensor is fitted to the coolant expansion tank, also commonly referred to as the coolant bottle or reservoir.

Its job is to monitor whether the coolant is at the required level. If the level falls below the specified point, the sensor communicates this to the vehicle's electronics so a warning can be displayed to the driver.

A correctly functioning coolant level sensor helps:

• Monitor coolant level within the expansion tank
• Alert the driver when coolant becomes too low
• Provide early warning of coolant loss
• Reduce the risk of driving with insufficient coolant
• Support correct operation of the cooling system warning functions

The sensor does not measure engine temperature and does not control coolant flow. Its purpose is specifically to monitor coolant level.

Why Is Coolant Level Monitoring Important?

The engine cooling system relies on having the correct quantity of coolant circulating through the engine, radiators and associated components.

A falling coolant level can indicate a leak or another cooling system problem. If coolant loss continues unnoticed, the cooling system may become unable to control engine temperature effectively.

The coolant level sensor therefore provides an important early warning, allowing the cooling system to be inspected before a low coolant condition develops into a more serious problem.

Why Do Coolant Level Sensors Fail?

Coolant level sensors operate in a demanding environment and can deteriorate with age and repeated heating and cooling cycles.

Common causes of failure include:

• Age-related electrical deterioration
• Repeated temperature cycling
• Internal sensor failure
• Coolant contamination or deposits
• Corrosion at electrical connections
• Damaged wiring or connectors
• Damage during expansion tank removal or replacement

A problem with the expansion tank, wiring or electrical connector can produce similar symptoms, so these components should also be inspected before replacing the sensor.

When Should the Coolant Level Sensor Be Replaced?

Replacement should be considered if:

• A low coolant warning remains on despite the coolant being at the correct level
• Low coolant warnings appear intermittently without an actual loss of coolant
• The sensor fails diagnostic testing
• The sensor or electrical connection is physically damaged
• Corrosion is present around the connection
• The sensor has been damaged during cooling system maintenance
• The coolant expansion tank is being replaced and the existing sensor is no longer serviceable

If the vehicle displays a low coolant warning, the actual coolant level should always be checked first. A warning should not automatically be assumed to be caused by a faulty sensor.

Important Cooling System Checks

If the coolant level is genuinely low, the cause should be investigated rather than simply topping up the expansion tank.

Potential coolant loss can occur from components such as hoses, expansion tanks, radiators, water pumps, seals and other cooling system connections.

Replacing the level sensor is appropriate when the sensor itself has been identified as faulty.

A worn starter motor can result in increasingly slow or intermittent cranking and may eventually leave the vehicle unable to start. This OE Match unit provides a replacement solution for a worn, unreliable or failed original starter.

What Does a Starter Motor Do?

The starter motor converts electrical energy from the vehicle's battery into mechanical rotation.

When the vehicle is started, the starter motor engages with the engine's flywheel or drive plate and rotates the crankshaft. This creates the initial engine movement required for the combustion process to begin. Once the engine starts, the starter disengages.

A correctly functioning starter motor provides:

• Strong and consistent engine cranking
• Reliable cold and hot starting
• Correct engagement with the engine
• Efficient use of battery power
• Fast engine start-up

Why Do Starter Motors Fail?

Starter motors are powerful electrical components that experience substantial loads every time the engine is started. Internal components gradually wear, while engine-bay heat and repeated heat cycles can accelerate deterioration.

Common causes of starter motor failure include:

• Worn internal brushes
• Solenoid deterioration
• Worn bearings or bushes
• Wear to the starter drive mechanism
• Electrical connection problems
• Internal electrical faults
• Heat-related deterioration
• Age and high mileage
• Repeated starting cycles

A weak battery or poor electrical connection can produce symptoms similar to a failing starter, so the battery, terminals and main electrical connections should also be checked before replacement.

When Should a Starter Motor Be Replaced?

Replacement should be considered if:

• The engine cranks noticeably slower than normal
• Starting becomes intermittent
• A clicking sound is heard but the engine does not crank
• The starter occasionally fails to engage
• Grinding or unusual noises occur during starting
• Starting becomes particularly difficult when the engine is hot
• The starter motor has been diagnosed with an internal electrical or mechanical fault
• The starter no longer operates

Starter motors do not normally have a fixed replacement interval. They should generally be replaced when testing confirms deterioration or failure.

A healthy starter motor is essential for dependable operation. As these vehicles age, starter motors can develop internal wear that results in slower cranking, intermittent operation or complete starting failure.

Starting problems should be diagnosed carefully because similar symptoms can also result from a weak battery, poor battery terminals, damaged cables or other electrical faults.

Once a starter motor has been identified as the cause, replacing the worn unit restores the mechanical cranking action required to start the engine reliably.

When replacing a Porsche starter motor, it is also worthwhile checking the battery condition, main power cables, earth connections and associated starting-system wiring.

Chrome Grille for Additional Headlight 

Restore the distinctive front-end appearance of your classic Porsche with this OE Match Chrome Grille for the additional headlight/fog light position.
                     
Fits:

• Porsche 914 (1970-1976)   

Diagram ref no 15 (Left) / 18 (Right)      

Located in the front bumper area, these grilles surround the additional light opening and form an important part of the characteristic Porsche 914 front-end design. The chrome finish provides the correct classic appearance and makes these grilles particularly suitable for restoration or replacement of damaged, faded or missing originals.

What Does the Additional Headlight Grille Do?

The grille fits around the additional headlight or fog light opening at the front of the Porsche 914. Its primary purpose is to provide a neat surround for the light while completing the styling of the front bumper area.

A correctly fitted grille helps:

• Provide the correct surround for the additional headlight/fog light
• Protect the light area from larger road debris
• Maintain the correct appearance of the front bumper
• Finish the opening neatly around the lamp
• Restore the classic chrome detailing of the Porsche 914

These versions feature the opening for cars equipped with the additional fog light.

Why Do Porsche 914 Grilles Fail?

Because they are mounted low at the front of the vehicle, the grilles are continually exposed to weather, road dirt and debris.

After decades of use, common problems can include:

• Stone chip and impact damage
• Cracked or broken grille sections
• Deterioration of the chrome finish
• Scratches and surface damage
• Discolouration and weathering
• Damaged mounting points

Age can also make original components increasingly fragile, particularly when they are removed during front bumper or fog lamp servicing.

When Should the Grille Be Replaced?

Replacement should be considered if:

• The grille is cracked or broken
• Chrome plating is badly deteriorated
• Mounting points are damaged
• The grille no longer sits securely
• Sections of the grille are missing
• One side has been lost or previously removed
• The fog lights are being refurbished
• The front bumper is undergoing restoration

Replacing tired or mismatched left and right-hand grilles can make a noticeable improvement to the appearance of a restored Porsche 914.
