Diagram Ref No 35

The sensor measures the temperature of exhaust gases and sends this information to the vehicle's engine management system. Accurate exhaust-temperature information allows the control system to monitor operating conditions and, depending on the vehicle and engine specification, manage strategies designed to protect emissions equipment, turbocharger and exhaust components from excessive temperatures.

A faulty exhaust gas temperature sensor can provide inaccurate readings or stop communicating altogether, potentially triggering warning lights, diagnostic fault codes and protective engine-management strategies.

What This Product Does:
The exhaust gas temperature sensor, commonly abbreviated to EGT sensor, monitors the temperature of gases flowing through a specific part of the exhaust system.

Exhaust temperatures can become extremely high, particularly during high engine loads and certain emissions-control operating conditions.

The sensor converts temperature information into an electrical signal that can be interpreted by the vehicle's control system.

Depending on the particular Porsche application, this information can be used to:

• Monitor exhaust gas temperature
• Support engine-management calculations
• Protect exhaust-system components from excessive heat
• Support emissions-system operation
• Monitor catalytic converter or particulate-filter operating conditions where applicable
• Assist thermal-management strategies
• Help protect turbocharger and exhaust components where applicable
• Detect abnormal exhaust-temperature conditions

Accurate temperature information is therefore important for both performance monitoring and component protection.

Symptoms Of Wear Or Failure:
A faulty EGT sensor may produce several symptoms depending on the vehicle and type of failure.

Possible signs include:

• Check-engine warning light
• Exhaust or emissions-system warning
• Stored diagnostic trouble codes
• Implausible exhaust-temperature readings
• Intermittent temperature readings
• Loss of sensor communication
• Reduced engine performance
• Protective or limp-home mode
• Changes in emissions-system operation
• Increased fuel consumption
• Regeneration-related problems on vehicles equipped with a particulate filter
• Recurring warning messages after fault codes are cleared

Some sensor failures may initially cause no noticeable drivability symptoms other than a warning light.

Why Replacement Matters:
A correctly operating exhaust gas temperature sensor allows the vehicle's control system to know what is happening thermally inside the exhaust system.

Replacing a confirmed faulty sensor helps:

• Restore accurate exhaust-temperature monitoring
• Resolve associated sensor fault codes
• Restore correct engine-management information
• Support emissions-system operation
• Maintain thermal protection strategies
• Reduce the risk of incorrect protective intervention
• Support correct particulate-filter operation where applicable
• Restore reliable communication between the exhaust system and control unit

Ignoring a failed sensor can leave the engine-management system without accurate information needed for exhaust thermal management.

• Providing a clean and finished factory appearance
• Helping shield surrounding components from dirt and debris
• Reducing direct contact between luggage and the vehicle structure
• Helping protect against minor moisture and contamination
• Providing a durable surface for everyday storage
• Helping prevent loose items from directly contacting concealed areas
• Maintaining the original appearance of the luggage compartment

The liner is primarily a protective and cosmetic component rather than a mechanical part.

Symptoms Of Wear Or Failure:
Plastic luggage compartment trim does not usually suffer mechanical failure. Instead, deterioration normally occurs through age, impact, repeated loading and unloading, heat or previous removal.

Common signs of damage include:

• Cracks in the plastic
• Broken sections
• Split mounting points
• Missing retaining areas
• Deep scratches
• Heavy scuffing
• Warped or distorted plastic
• Loose fitment

• Poor alignment with surrounding trim
• Damaged edges
• Discolouration
• Missing sections
• Previous adhesive or temporary repairs

Minor scratches may only affect appearance, while cracks or broken mounting points can prevent the liner from remaining securely installed.

Why Replacement Matters:
Although the luggage compartment liner is not normally a safety-critical mechanical component, replacing a badly damaged one has several benefits.

A replacement liner helps:

• Restore the original luggage compartment appearance
• Protect underlying areas and components
• Provide a durable storage surface
• Eliminate broken or loose plastic sections
• Reduce rattles caused by damaged trim

Diagram Ref No 2

The return line carries power steering fluid back through the hydraulic system after it has assisted steering operation. Maintaining a sealed and unrestricted return path is essential for correct fluid circulation, consistent steering assistance and protection of the power steering pump and associated components.

As a Genuine Porsche component, this line is manufactured for the intended factory installation and is suitable for replacing an original return line that has become cracked, leaking, corroded or otherwise damaged.

What This Product Does:
A hydraulic power steering system uses pressurised fluid to reduce the amount of effort required to turn the steering wheel.

The power steering pump circulates hydraulic fluid through the system. After the fluid has performed its steering-assistance function, it must return through the system so that it can be recirculated.

The power steering return line provides this return path.

Its functions include:

• Returning hydraulic fluid through the power steering system
• Maintaining continuous power steering fluid circulation
• Helping maintain correct hydraulic system operation
• Preventing fluid from escaping from the system
• Supporting consistent steering assistance
• Helping protect the power steering pump from low-fluid operation

Although the return side generally operates at lower pressure than the main pressure supply line, it must still remain properly sealed and free from restrictions.

Symptoms Of Wear Or Failure:
Power steering lines are exposed to heat, vibration, hydraulic fluid, road contamination and ageing.

Over time, deterioration can result in leaks or restricted fluid flow.

Common symptoms include:

• Power steering fluid underneath the vehicle
• Visible fluid around the return line
• Damp or oily hose connections
• Falling power steering fluid level
• Frequent need to top up the reservoir
• Heavier steering effortIntermittent power steering assistance
  
• Whining or groaning from the power steering pump
• Foaming or aeration in the fluid reservoir
• Burning smell if fluid reaches hot components
• Visible cracking or deterioration of flexible hose sections
• Corrosion on metal sections or fittings
• Damaged or loose connections

Any unexplained loss of power steering fluid should be investigated promptly.

Why Replacement Matters:
The return line is essential for maintaining a sealed and correctly circulating hydraulic power steering system.

Replacing a damaged or leaking line helps:

• Stop power steering fluid loss
• Restore correct hydraulic fluid circulation
• Maintain consistent steering assistance
• Reduce the risk of air entering the system
• Protect the power steering pump
• Prevent fluid contamination of surrounding components
• Restore the reliability of the steering system

Because steering is a safety-critical vehicle system, known hydraulic leaks or damaged lines should be repaired promptly.

Exhaust Gasket, Manifold To Downpipe, LHD. 
The Genuine Porsche Exhaust Gasket 477253115E is a replacement sealing component designed for the connection between the exhaust manifold and downpipe on compatible left-hand-drive (LHD) Porsche applications.

Fits:

• Porsche 924 2.0L 1976-79
• Porsche 924 2.0L 1980-85 

 
Diagram Ref No 11

This gasket creates a gas-tight seal at an important exhaust-system joint, preventing hot exhaust gases from escaping before they continue through the downpipe and the rest of the exhaust system.

Constant exposure to extreme temperatures, exhaust gases and repeated heating and cooling cycles can cause an old gasket to deteriorate, compress or burn through. Replacing a failed gasket helps restore a properly sealed exhaust connection, reduce unwanted exhaust noise and prevent hot gases leaking around the manifold-to-downpipe joint.

What This Product Does:
The exhaust gasket sits between the mating surfaces of the exhaust manifold and downpipe, creating a seal when the components are secured together.

Exhaust gases leave the engine at high temperature and pressure. These gases must remain contained within the exhaust system as they travel away from the engine.

The gasket helps:

• Create a gas-tight manifold-to-downpipe connection
• Prevent exhaust gases escaping through the joint
• Reduce unwanted exhaust noise
• Maintain proper exhaust-system integrity
• Protect surrounding components from escaping hot gases
• Prevent exhaust fumes leaking from the connection
• Maintain a secure seal despite repeated thermal expansion and contraction

Although relatively small, the gasket plays an important role in keeping the exhaust system correctly sealed.

Symptoms Of Wear Or Failure:
A deteriorated manifold-to-downpipe gasket can allow exhaust gases to escape through the connection.

Common symptoms may include:

• Ticking, tapping or blowing noise from the exhaust joint
• Increased exhaust noise
• Hissing or puffing sounds during acceleration
• Exhaust fumes or odour around the engine or underside of the vehicle
• Black soot deposits around the manifold-to-downpipe connection
• Visible signs of exhaust gas leakage
• Reduced exhaust-system sealing
• Noise that becomes more noticeable under load
• Heat damage or discolouration around the leaking joint
• Engine or emissions-related faults where applicable

A small leak may initially only be noticeable when the engine is cold or under acceleration.

Why Replacement Matters:
A leaking exhaust gasket should not be ignored.

Replacing a worn or damaged manifold-to-downpipe gasket helps:

• Restore a properly sealed exhaust connection
• Prevent hot exhaust gases escaping from the joint
• Reduce blowing, ticking and hissing noises
• Prevent soot accumulation around the connection
• Protect nearby components from concentrated exhaust heat
• Reduce the possibility of exhaust fumes entering areas where they should not
• Maintain correct exhaust-system operationRestore a cleaner and quieter exhaust system

A deteriorated gasket can progressively worsen as hot gases erode the sealing area.

• Maintain an airtight intake connection
• Prevent vacuum and intake air leaks
• Reduce unwanted or unmetered air entering the engine
• Support stable engine idle
• Maintain consistent engine performance
• Support correct air/fuel mixture control
• Maintain intake-system integrity

Even a relatively small leak can affect engine operation, particularly at idle when intake vacuum can be significant.

Symptoms Of Wear Or Failure:
A deteriorated intake seal can allow air to enter through the manifold connection rather than through the intended intake path.

Possible symptoms include:

• Rough or unstable idle
• Higher than normal idle speed
• Fluctuating or hunting idle
• Engine hesitation
• Reduced throttle response
• Poor or inconsistent engine performance
• Lean-running symptoms
• Difficult starting
• Engine misfires
• Increased fuel consumption
• Engine warning light on vehicles with applicable diagnostics
• Air/fuel mixture or lean-condition fault codes where applicable
• Hissing or whistling noise from the intake area

Symptoms may vary according to the size and location of the leak.

Why Replacement Matters:
An intake air leak can affect the engine's ability to maintain the intended air/fuel mixture and stable operating conditions.

Replacing a deteriorated intake manifold connector seal helps:

• Restore an airtight intake connection
• Prevent unwanted air or vacuum leakage
• Improve idle stability
• Support consistent throttle response
• Maintain correct intake-system operation
• Support accurate air/fuel mixture control
• Reduce lean-running problems caused by intake leaks
• Restore reliable engine performance

Ignoring an intake leak can result in persistent drivability problems and make accurate engine tuning or diagnosis more difficult.

High-quality GKN CV joint boot kit GKNB20647 for selected Porsche Panamera 971 / 976  & Taycan drivetrain applications.

The CV joint boot is an essential protective component of the driveshaft assembly. Its purpose is to retain the specialised CV joint grease while preventing water, dirt, road debris and other contaminants from entering the joint.

This GKN boot is manufactured from TPE - thermoplastic elastomer, a durable material particularly suited to modern high-performance drivetrains where CV joints can operate at elevated temperatures and under substantial torque loads.

Designed for a tripod-type CV joint, the GKNB20647 provides the precise fit required to maintain an effective seal around the joint and driveshaft.

A damaged or split CV boot should be replaced as soon as possible. Once the boot loses its seal, grease can escape and contamination can enter the joint, potentially causing accelerated CV joint wear and eventually requiring replacement of the complete joint or driveshaft.

Diagram Ref No 1 And 2

The cylinder head gasket must withstand high combustion pressures, elevated operating temperatures and constant heating and cooling cycles. Its primary role is to maintain compression and combustion sealing while keeping oil, coolant and combustion areas correctly separated where applicable to the engine design.

A damaged or incorrectly sealing head gasket can cause compression loss, overheating, fluid leakage and poor engine performance. If left unresolved, cylinder head gasket failure can potentially result in extensive internal engine damage.

What This Product Does:
The cylinder head gasket creates a high-pressure seal between the cylinder head and engine assembly.

During combustion, considerable pressure is generated inside the cylinders. The gasket must contain this pressure while maintaining separation between the combustion chambers and the engine's oil and coolant passages where applicable.

A correctly functioning cylinder head gasket helps:

• Maintain cylinder compression
• Contain combustion pressure
• Prevent combustion gases escaping through the cylinder head joint
• Keep engine oil and coolant within their intended passages
• Prevent unwanted mixing of engine fluids
• Support consistent combustion and engine performance
• Help maintain correct operating temperatures
• Maintain the integrity of the cylinder head assembly

The gasket must continue performing these functions despite repeated expansion and contraction of the surrounding engine components.

Symptoms Of Wear Or Failure:
Cylinder head gasket failure can produce different symptoms depending on where the sealing interface has been compromised.

Possible warning signs include:

• Engine overheating
• Loss of cylinder compression
• Reduced engine power
• Rough or uneven running
• Engine misfires
• Difficult starting
• Unexplained coolant loss
• Oil leakage around the cylinder head joint
• Abnormal exhaust smoke or vapour
• Increased cooling-system pressure
• Combustion gases entering the cooling system
• Oil contamination of coolant
• Coolant contamination of engine oil
• Increased oil consumption

A failing head gasket does not necessarily produce an obvious external leak. Internal leakage between combustion chambers or fluid passages may require diagnostic testing to identify.

Why Replacement Matters:
A failed cylinder head gasket can affect several critical engine functions simultaneously.

Loss of combustion sealing can reduce compression and performance, while leakage between oil or coolant passages can cause fluid contamination and temperature-control problems.

Replacing a failed gasket helps:

• Restore cylinder compression
• Restore combustion sealing
• Prevent combustion gas leakage
• Prevent unwanted oil or coolant leakage where applicable
• Maintain separation between engine fluid circuits
• Support stable engine operating temperatures
• Restore consistent engine performance
• Reduce the risk of progressive internal engine damage

Continuing to operate an engine with a failed head gasket can potentially lead to overheating, lubrication problems, cylinder head damage and substantially more extensive repairs.

Diagram Ref No 2 And 3

A cylinder head gasket is one of the engine's most important sealing components. It helps maintain cylinder compression and combustion sealing while keeping engine fluids within their intended passages where applicable.

Over time, repeated heat cycles, overheating, component distortion or incorrect installation can compromise the gasket. A failed cylinder head gasket can lead to compression loss, fluid leakage, overheating and potentially significant engine damage if the problem is ignored.

What This Product Does:
The cylinder head gasket creates a high-integrity seal between the cylinder head and its mating engine surface.

During combustion, extremely high pressure is generated inside each cylinder. The gasket must contain this pressure while also maintaining separation between adjacent engine passages where required.

A correctly functioning cylinder head gasket helps:

• Maintain cylinder compression
• Seal combustion pressure
• Prevent combustion gases escaping from the cylinder
• Keep oil and coolant within their intended passages where applicable
• Prevent unwanted mixing of engine fluids
• Maintain consistent engine performance
• Support correct engine operating temperature
• Maintain overall cylinder head sealing integrity

The gasket must continue performing these functions while repeatedly expanding and contracting as the engine heats up and cools down.

Symptoms Of Wear Or Failure:
Cylinder head gasket failure can produce a wide range of symptoms depending on where and how the sealing surface has failed.

Possible symptoms include:

• Engine overheating
• Loss of compression
• Reduced engine performance
• Rough running or misfiring
• Difficult starting
• Uneven cylinder performance
• Unexplained coolant loss where applicable
• Engine oil leakage around the cylinder head joint
• Abnormal exhaust smoke
• Increased pressure within the cooling system
• Oil or coolant contamination
• Combustion gases entering the cooling system
• Bubbles or abnormal pressure in the coolant expansion system
• Increased oil consumption

A failing gasket does not always produce an obvious external leak. Internal leakage can occur between combustion chambers or fluid passages.

Why Replacement Matters:

A failed cylinder head gasket should not be treated as a minor engine leak.

Once sealing integrity has been compromised, combustion pressure or engine fluids may begin travelling into areas where they should not be present.

Replacing a failed gasket helps:

• Restore cylinder compression
• Restore combustion sealing
• Prevent combustion gas leakage
• Prevent unwanted oil or coolant leakage where applicable
• Maintain separation between engine fluid circuits
• Support stable engine temperatures
• Restore consistent engine performance
• Reduce the risk of progressive engine damage

Continuing to operate an engine with a failed cylinder head gasket can potentially cause overheating, cylinder head damage, contaminated lubrication and more extensive internal engine problems.

Diagram Ref No 8

Cylinder head sealing is essential for correct engine performance. The gasket helps maintain the required seal between mating engine components, preventing combustion pressure and engine fluids from escaping into areas where they do not belong.

Because this gasket operates in an extremely demanding environment, deterioration, overheating, incorrect installation or engine component distortion can eventually compromise its sealing ability. A failed cylinder head gasket should be addressed promptly to prevent further engine damage.

What This Product Does:
The cylinder head gasket creates a high-integrity seal at the cylinder head interface.

Depending on the engine design, this sealing interface must withstand combustion pressure, high operating temperatures and the circulation of engine fluids through adjacent passages.

A correctly functioning cylinder head gasket helps:

• Maintain cylinder and combustion sealing
• Prevent combustion gases escaping from the sealing interface
• Keep engine fluids within their intended passages
• Maintain correct engine compression
• Support consistent engine performance
• Protect adjoining engine components from leakage
• Maintain the integrity of the cylinder head assembly

Unlike a simple external seal, a cylinder head gasket must continue sealing while exposed to substantial pressure and repeated thermal expansion and contraction.

Symptoms Of Wear Or Failure:
Cylinder head gasket failure can present in different ways depending on where the gasket has lost its seal.

Possible symptoms include:

• Loss of engine compression
• Reduced engine performance
• Rough running or misfiring
• Difficult starting
• Abnormal combustion leakage
• Oil leakage around the cylinder head sealing area
• Unusual engine temperatures or overheating
• Increased oil consumption
• Abnormal exhaust smoke
• Unexplained fluid loss where applicable
• Contamination between fluid passages where applicable
• Unusual pressure within associated engine systems

External signs may include visible staining, seepage or deposits around the cylinder head joint.

Some cylinder head gasket problems may not produce an obvious external leak, making correct diagnosis important before dismantling the engine.

Why Replacement Matters:
A compromised cylinder head gasket can affect compression, engine performance and sealing integrity.

Continuing to operate an engine with a failed gasket may allow a relatively localised sealing problem to develop into more extensive engine damage.

Replacing a failed cylinder head gasket helps:

• Restore the cylinder head sealing interface
• Maintain correct compression
• Prevent combustion gas leakage
• Reduce engine fluid leakage where applicable
• Restore consistent engine operation
• Protect surrounding engine components
• Reduce the risk of further engine damage

Cylinder head gasket problems should therefore be investigated promptly rather than treated as a minor leak.
