Diagram Ref No 1

The coolant expansion tank, also known as the coolant reservoir or header tank, forms an important part of the engine cooling system. As engine temperature rises, coolant expands and system pressure increases. The expansion tank provides the necessary space for this change in coolant volume while helping the cooling system maintain the correct operating level and pressure.

As the engine cools, coolant contracts and is drawn back through the system. This continuous expansion and contraction means the tank is repeatedly exposed to high temperatures, pressure and thermal cycling.

Over time, plastic expansion tanks can become brittle, discoloured or cracked. Seams, hose connections and mounting areas may also deteriorate, eventually allowing coolant to escape. A leaking tank can lead to gradual coolant loss and, if ignored, potentially result in engine overheating.

Replacing a deteriorated tank with the correct Porsche Coolant Expansion Tank 95B121407A helps restore a sealed, reliable cooling system and correct coolant capacity.

What This Product Does:

• Stores the cooling system's reserve coolant.
• Provides space for coolant expansion as engine temperature increases.
• Helps accommodate changes in coolant volume during heating and cooling.
• Supports correct cooling-system pressure management.
• Provides a convenient point for checking coolant level.
• Helps ensure coolant remains available to the cooling circuit.
• Works with the expansion tank cap and associated hoses.
• Helps prevent coolant loss when the system is operating correctly.
• Supports consistent engine temperature management.
• Replaces a cracked, leaking or deteriorated coolant reservoir.
• Restores the integrity of the cooling system when tank failure is the cause.
• Is specified for compatible LHD Porsche applications.  

Symptoms Of Wear Or Failure:

• Visible coolant leakage around the tank.
• Coolant collecting underneath the vehicle.
• Repeatedly falling coolant level.
• Low coolant warning messages.
• Cracks in the plastic tank.
• Leakage from tank seams.
• Leakage around hose connections.
• Coolant residue or dried deposits around the tank.
• Sweet coolant smell from the engine compartment.
• Tank becoming heavily discoloured or brittle.
• Damage around mounting points.
• Coolant escaping when the system reaches operating temperature.
• Frequent need to top up coolant.
• Engine temperature running higher than normal.
• Cooling system unable to maintain pressure.
• Steam or coolant vapour from the engine compartment in severe cases.  

Why Replacement Matters:

• The expansion tank must remain sealed and structurally sound because it operates as part of a hot, pressurised cooling system.
• A small crack may initially produce only a minor leak when the engine is hot. However, repeated heating and cooling can cause cracks to grow, increasing coolant loss over time.
• Insufficient coolant reduces the cooling system's ability to transfer heat away from the engine. Coolant loss can also introduce air into the system, potentially causing poor circulation, temperature fluctuations and localised overheating.
• If coolant loss becomes severe, the engine can overheat. Continued operation under overheating conditions can result in expensive damage to gaskets, seals and major internal engine components.
• A leaking tank can also prevent the cooling system from maintaining its intended pressure. Correct system pressure is important because it helps control the coolant's boiling characteristics at normal operating temperatures.
• Replacing a cracked or deteriorated reservoir with the correct Porsche Coolant Expansion Tank 95B121407A helps restore cooling-system integrity, maintain the correct coolant level and reduce the risk of overheating caused by coolant loss.

Diagram Ref No 1

The control arm works together with its bushes, joints and surrounding suspension components to maintain the intended position of the front wheel throughout suspension travel. This is essential for maintaining correct steering response, wheel alignment, tyre contact and overall vehicle stability.

Control arms are subjected to constant loads from road surfaces, braking forces and cornering. Over time, their bushes or joints can wear, while the arm itself may be damaged by impacts, corrosion or accident damage. Wear can allow unwanted wheel movement, adversely affecting steering precision, alignment and tyre wear.

Replacing worn or damaged components with the correct Porsche Front Track Control Arms PAD407151A / PAD407152A helps restore the suspension geometry and controlled front axle behaviour intended for the vehicle.

What This Product Does:

• Locates and controls the front wheel within the suspension geometry.
• Connects the relevant wheel carrier to the suspension/chassis structure.
• Controls wheel movement during suspension travel.
• Helps maintain correct front wheel alignment.
• Supports accurate steering response.
• Helps maintain stable handling during cornering.
• Controls unwanted wheel movement during braking and acceleration.
• Helps keep the tyre correctly positioned against the road.
• Works with other suspension links, bushes and joints.
• Contributes to predictable front axle behaviour.
• Supports even and consistent tyre contact.
• Replaces a worn, bent or damaged original suspension arm.
• Helps restore factory-intended suspension performance.  

Symptoms Of Wear Or Failure:

• Knocking or clunking from the front suspension.
• Rattling noises when driving over uneven surfaces.
• Steering that feels loose or imprecise.
• Vehicle wandering or requiring frequent steering correction.
• Reduced steering response. Unstable handling during cornering.
• Steering wheel vibration. Vibration or movement under braking.
• Vehicle pulling to one side. Difficulty maintaining correct wheel alignment.
• Uneven or accelerated front tyre wear.
• Excessive movement in a control arm bush or joint.
• Cracked, split or deteriorated suspension bushes.
• Visible bending or deformation of the control arm.
• Damage following a kerb, pothole or accident impact.
• Abnormal tyre movement identified during suspension inspection.  

Why Replacement Matters:

• The front track control arm has a direct influence on suspension geometry and wheel location. Even relatively small amounts of wear in a bush or joint can allow the wheel to move away from its intended position as forces are applied.
• This unwanted movement can affect steering precision, braking stability and cornering behaviour. The vehicle may feel less predictable, particularly when travelling over uneven surfaces or changing direction quickly.
• Control arm wear can also prevent wheel alignment settings from remaining consistent. Although the vehicle may be aligned correctly while stationary, excessive movement within worn suspension components can cause geometry to change dynamically while driving.
• Incorrect or unstable geometry can accelerate tyre wear, potentially damaging otherwise serviceable tyres and reducing the quality of their contact with the road.
• A bent arm caused by pothole, kerb or collision damage can create similar problems. If the suspension cannot be aligned within specification, the control arm and surrounding components should be checked carefully for deformation.
• Replacing worn or damaged components with the correct Porsche Front Track Control Arms PAD407151A / PAD407152A helps restore accurate wheel location, predictable steering and stable suspension behaviour.

Lambda Oxygen Sensor, AFTER Catalytic Converter, Cyl 1-3.

Maintain accurate emissions monitoring and dependable catalytic converter diagnostics with this Porsche Lambda Oxygen Sensor, part number 958906262AB. Designed for compatible Porsche applications, this sensor is specified for the cylinders 1–3 exhaust bank and is positioned AFTER the catalytic converter.
Fits:

• Porsche 958 Cayenne V6 3.6L Petrol (300Hp) 2010-17

Cars With Option Codes:
7GB - Emission Standard ULEV 2
Diagram Ref No 32

Also known as a downstream, post-cat or O2 sensor, this lambda sensor measures the oxygen content of the exhaust gases after they have passed through the catalytic converter. The information is sent to the engine control unit (ECU), allowing it to monitor the performance and efficiency of the catalyst.

Unlike the lambda sensor positioned before the catalytic converter, which has a primary role in air-fuel mixture control, the downstream sensor is principally used to monitor catalytic converter operation and emissions-system performance.

The ECU can compare signals from the upstream and downstream oxygen sensors to determine whether the catalytic converter is processing exhaust gases as expected. An accurate downstream signal is therefore important for reliable onboard emissions diagnostics.

Continuous exposure to exhaust heat, vibration, moisture and combustion deposits can eventually cause the sensor to become slow, inaccurate or electrically faulty. Replacing a defective unit with the correct Porsche Lambda Oxygen Sensor 958906262AB helps restore accurate post-catalyst monitoring.
What This Product Does:

• Is specified for the cylinders 1–3 exhaust bank.
• Is positioned AFTER the catalytic converter.
• Measures oxygen content in exhaust gases leaving the catalyst.
• Sends post-catalyst oxygen information to the ECU.
• Helps monitor catalytic converter efficiency.
• Works in conjunction with the upstream lambda sensor.
• Supports onboard emissions-system diagnostics.
• Helps the ECU identify abnormal catalyst performance.
• Provides feedback used to monitor the emissions-control system.
• Helps identify genuine catalytic converter deterioration.
• Replaces a slow, contaminated, damaged or failed downstream sensor.
• Maintains the intended Porsche engine-management and emissions monitoring functions.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Downstream oxygen sensor-related diagnostic fault codes.
• Cylinders 1–3 bank sensor faults.
• Post-catalytic converter sensor fault codes.
• Catalyst-efficiency-related diagnostic codes.
• Intermittent engine-management warnings.
• Implausible or inconsistent oxygen sensor readings.
• Slow sensor response during diagnostic testing.
• Sensor output stuck at an abnormal value.
• Oxygen sensor heater circuit faults.
• Failed emissions testing where applicable.
• Damaged sensor wiring or insulation.
• Corroded or damaged electrical connectors.
• Physical sensor damage from heat, corrosion or road debris.  

Why Replacement Matters:

• The downstream lambda sensor is an important part of the vehicle's emissions monitoring and onboard diagnostic system. It allows the ECU to assess how effectively the catalytic converter is treating the exhaust gases.
• If the sensor becomes slow or inaccurate, the ECU may receive misleading information about catalytic converter performance. This can trigger persistent engine-management warnings or catalyst-efficiency fault codes even when the catalyst itself is functioning correctly.
• A failed sensor heater circuit can also prevent the sensor from reaching its intended operating temperature efficiently, potentially interfering with emissions monitoring and generating additional diagnostic faults.
• Accurate downstream sensor operation is also valuable when diagnosing a genuinely deteriorated catalytic converter. Without a reliable sensor signal, distinguishing between a sensor problem and catalyst failure becomes more difficult.
• Replacing a confirmed defective sensor can therefore help avoid unnecessary replacement of significantly more expensive exhaust components.
• Replacing a faulty unit with the correct Porsche Lambda Oxygen Sensor 958906262AB helps restore accurate monitoring of the cylinders 1–3 catalyst, dependable emissions diagnostics and correct engine-management operation.

Lambda Oxygen Sensor, BEFORE Catalyst.
Maintain accurate air-fuel mixture monitoring, efficient combustion and dependable engine-management performance with this Porsche Lambda Oxygen Sensor, part numbers 958906262C and 958906262B. Designed for compatible Porsche applications, this sensor is positioned BEFORE the catalytic converter, where it monitors oxygen levels in the exhaust gases immediately after combustion.  

Fits:

• Porsche 955 Cayenne 3.2L V6 2004-06  

Diagram Ref No 26 And 27

Also known as an upstream, pre-cat or O2 sensor, the lambda sensor provides critical feedback to the engine control unit (ECU). By measuring residual oxygen in the exhaust stream, it enables the ECU to determine whether the engine is operating with a rich or lean air-fuel mixture and make continuous adjustments to fuel delivery.

Because this sensor is positioned upstream of the catalyst, it plays an important role in closed-loop fuel control. Accurate readings help maintain the correct air-fuel mixture for engine performance, fuel efficiency and emissions control.

Lambda sensors operate in an extremely demanding environment and are continuously exposed to high exhaust temperatures, vibration and combustion deposits. Over time, the sensing element can become contaminated or slow to respond, while the internal heater circuit, wiring or electrical connections may also deteriorate.

Replacing a faulty unit with the correct Porsche Lambda Oxygen Sensor 958906262C / 958906262B helps restore accurate exhaust monitoring and proper engine-management operation.

What This Product Does:

• Is designed for installation BEFORE the catalytic converter.
• Measures oxygen content within the exhaust gases.
• Sends exhaust oxygen information to the ECU.
• Helps determine whether the engine is running rich or lean.
• Allows the ECU to continually adjust fuel delivery.
• Supports accurate closed-loop air-fuel mixture control.
• Helps maintain efficient combustion.
• Supports smooth and responsive engine performance.
• Helps optimise fuel consumption.
• Contributes to correct exhaust emissions.
• Helps the ECU adapt fuelling to changing operating conditions.
• Helps protect the catalytic converter from problems associated with incorrect fuelling.
• Replaces a worn, contaminated, slow or failed lambda sensor.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Lambda or oxygen sensor-related diagnostic fault codes.
• Rich or lean mixture fault codes. Increased fuel consumption.
• Rough or unstable idle. Hesitation during acceleration.
• Poor throttle response. Reduced engine performance.
• Engine running excessively rich or lean.
• Strong fuel smell from the exhaust.
• Increased exhaust emissions.
• Failed emissions testing where applicable.
• Intermittent engine-management warnings.
• Slow lambda sensor response during diagnostic testing.
• Implausible or inconsistent oxygen sensor readings.
• Sensor heater circuit-related faults.
• Damaged sensor wiring or electrical connectors.  

Why Replacement Matters:

• The lambda sensor positioned before the catalytic converter is a key component of the engine's fuel-management system. The ECU relies on its signal to continually fine-tune fuel delivery according to actual combustion conditions.
• As a lambda sensor ages, its response can become progressively slower or less accurate without immediately failing completely. This can cause less precise fuel corrections and may contribute to increased fuel consumption, reduced performance, unstable running and higher emissions.
• Incorrect fuelling can also affect the catalytic converter. An excessively rich mixture may allow unburned fuel to enter the exhaust, increasing catalyst temperatures and potentially shortening catalytic converter service life.
• A failed sensor can cause the ECU to use substitute values or an alternative operating strategy. Although the engine may continue to run, overall efficiency, performance and emissions can be compromised.
• A malfunctioning lambda sensor can also trigger persistent engine-management warnings and make diagnosis of other fuel or emissions-related problems more difficult.
• Replacing a defective sensor with the correct Porsche Lambda Oxygen Sensor 958906262C / 958906262B helps restore accurate mixture feedback, efficient combustion and dependable engine-management performance.

Diagram Ref No 6

On turbocharged engines, accurate boost pressure information is essential. The ECU uses the sensor signal to monitor the pressure produced by the turbocharging system and manage engine operation according to load, throttle demand and operating conditions.

A correctly functioning boost pressure sensor helps the engine-management system maintain the intended balance between performance, efficiency and engine protection. If the sensor becomes contaminated, damaged or electrically faulty, it may provide inaccurate or intermittent pressure readings. This can result in reduced performance, inconsistent boost delivery, warning lights or the engine entering a protective operating mode.

The Porsche Boost Pressure Sensor PAC906051 provides the correct replacement solution for a faulty or damaged sensor, helping restore accurate boost pressure feedback and reliable engine-management operation.

What This Product Does:

• Measures pressure within the applicable intake/boost system.
• Sends boost pressure information to the ECU.
• Allows the engine-management system to monitor turbocharger performance.
• Helps regulate boost according to engine operating conditions.
• Supports accurate engine load calculation and control strategies.
• Helps maintain consistent turbocharged engine performance.
• Supports smooth and predictable power delivery.
• Helps the ECU identify overboost or underboost conditions.
• Contributes to efficient engine operation.
• Supports engine protection strategies.
• Provides important information for engine-management diagnostics.
• Replaces a contaminated, inaccurate, damaged or failed boost pressure sensor.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Boost pressure-related diagnostic fault codes.
• Reduced engine power. Poor acceleration.
• Sluggish throttle response.
• Inconsistent turbocharger boost.
• Sudden loss of boost pressure.
• Engine entering a reduced-power or protective mode.
• Underboost or overboost fault codes.
• Hesitation during acceleration.
• Uneven or unpredictable power delivery.
• Increased fuel consumption.
• Rough or inconsistent engine operation.
• Implausible boost pressure readings during diagnostic testing.
• Sensor readings that do not correspond with actual engine load.
• Damaged wiring or electrical connector.
• Contamination of the sensor's pressure-sensing element.  

Why Replacement Matters:

• Accurate boost pressure information is critical to the operation of a turbocharged engine. The ECU needs to know the pressure within the intake system so it can determine whether actual boost corresponds with the required operating conditions.
• If the sensor reports incorrect pressure, the ECU may make inappropriate control decisions or detect a discrepancy between requested and measured boost.
• A faulty sensor can therefore result in reduced performance even when the turbocharger itself is functioning correctly. The ECU may limit boost or enter a protective operating strategy when it cannot rely on the pressure signal.
• Conversely, accurate boost monitoring is important for identifying conditions where pressure is higher than intended. Excessive boost can increase mechanical and thermal loads on the engine and turbocharging system, making reliable pressure monitoring an important part of the engine protection strategy.
• A deteriorating sensor can also cause intermittent faults that are difficult to diagnose because the vehicle may perform normally under some conditions but lose power under others.
• Replacing a defective sensor with the correct Porsche Boost Pressure Sensor PAC906051 helps restore accurate pressure feedback, consistent turbocharger operation and dependable engine-management performance.

Diagram Ref No 2

Maintaining sufficient coolant is essential for controlling engine temperature. A low coolant level can reduce the cooling system's ability to transfer heat effectively and may allow air to enter the system, potentially resulting in unstable temperatures or overheating.

The coolant level sensor provides an important early warning so that coolant loss can be investigated before it develops into a more serious cooling-system problem. Over time, the sensor can become unreliable through age, repeated heat cycles, contamination, electrical faults or damage to its connector and wiring.

Replacing a faulty sensor with the correct Porsche Coolant Bottle Level Sensor 98764150300 helps restore accurate coolant level detection and reliable operation of the vehicle's coolant warning system.
What This Product Does:

• Monitors coolant level within the expansion/header tank.
• Detects when coolant falls below the intended level.
• Sends coolant level information to the vehicle's monitoring system.
• Helps trigger a low coolant warning when required.
• Provides early indication of coolant loss.
• Helps the driver identify a potential cooling-system problem.
• Supports reliable engine temperature management.
• Helps prevent low coolant conditions from going unnoticed.
• Works as part of the vehicle's cooling-system warning arrangement.
• Replaces a damaged, inaccurate or failed coolant level sensor.
• Restores correct coolant level monitoring on compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Low coolant warning despite the coolant being at the correct level.
• Coolant warning appearing intermittently.
• Warning remaining illuminated after the coolant level has been corrected.
• No low coolant warning when the level is genuinely low.
• Implausible coolant level information during diagnostic testing.
• Coolant level sensor-related fault codes where applicable.
• Warning appearing particularly when cornering or accelerating despite adequate coolant.
• Corroded or contaminated electrical connections.
• Damaged sensor wiring.
• Cracked or damaged electrical connector.
• Physical deterioration of the sensor.
• Sensor problems discovered during expansion tank servicing or replacement.  

Why Replacement Matters:

• The coolant level sensor provides an important warning when the cooling system begins losing coolant. A faulty sensor can create problems in two different ways.
• If the sensor incorrectly reports a low level, it may produce persistent or intermittent dashboard warnings even when the cooling system is correctly filled. Apart from being inconvenient, repeated false warnings can make it more difficult to recognise a genuine cooling-system problem.
• More importantly, a sensor that fails to detect an actual low coolant condition can prevent the driver from receiving an early warning.
• Coolant loss may result from a leaking hose, radiator, expansion tank, water pump, seal or another cooling-system component. Continuing to drive with insufficient coolant can lead to poor circulation, air entering the cooling circuit and eventual engine overheating.
• Severe overheating can cause expensive engine damage, including deterioration of seals and gaskets and damage to major engine components.
• Replacing a defective sensor with the correct Porsche Coolant Bottle Level Sensor 98764150300 helps ensure the vehicle can accurately monitor coolant level and provide an appropriate warning when attention is required.

Diagram Ref No 18

Also known as an upstream, pre-cat or O2 sensor, the lambda sensor measures the oxygen content remaining in the exhaust gases after combustion. This information is transmitted to the engine control unit (ECU), allowing it to determine whether the engine is operating with a rich or lean air-fuel mixture and make precise adjustments to fuel delivery.

Because this sensor is located before the catalytic converter, it plays a key role in closed-loop fuel control. Accurate sensor readings help the engine-management system maintain efficient combustion, responsive performance, appropriate fuel consumption and controlled exhaust emissions.

Lambda sensors operate in extremely demanding conditions, with constant exposure to high exhaust temperatures, vibration and combustion deposits. Over time, the sensing element may become contaminated or slow to respond, while the internal heater circuit, wiring or connector can also deteriorate.

Replacing a faulty sensor with the correct Porsche Right Lambda Oxygen Sensor 958906262G helps restore accurate exhaust monitoring and proper engine-management operation.

What This Product Does:

• Is designed for the RIGHT-side application.
• Is positioned BEFORE the catalytic converter.
• Measures oxygen levels within the exhaust gases.
• Sends exhaust oxygen information to the ECU.
• Helps determine whether the air-fuel mixture is rich or lean.
• Allows the ECU to make continuous fuel-delivery corrections.
• Supports accurate closed-loop mixture control.
• Helps maintain efficient combustion.
• Supports smooth throttle response and engine performance.
• Helps optimise fuel consumption.
• Contributes to correct exhaust emissions.
• Helps protect the catalytic converter from problems caused by incorrect fuelling.
• Replaces a worn, contaminated, damaged or failed lambda sensor.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Lambda or oxygen sensor-related diagnostic fault codes.
• Bank-specific rich or lean mixture fault codes.
• Increased fuel consumption.
• Rough or unstable idle.
• Hesitation during acceleration.
• Poor throttle response.
• Reduced engine performance.
• Engine running excessively rich or lean.
• Strong fuel smell from the exhaust.
• Increased exhaust emissions.
• Failed emissions testing where applicable.
• Intermittent engine-management warnings.
• Slow sensor response during diagnostic testing.
• Implausible or inconsistent lambda readings.
• Oxygen sensor heater circuit faults.
• Damaged sensor wiring or electrical connectors.  

Why Replacement Matters:

• The lambda sensor located before the catalytic converter provides important feedback that allows the ECU to continually fine-tune the engine's air-fuel mixture.
• A healthy sensor responds quickly to changing exhaust oxygen levels. As the sensor ages or becomes contaminated, its response may become slower or inaccurate. This can interfere with the ECU's ability to make precise fuel corrections.
• Poor mixture control may result in increased fuel consumption, reduced performance, unstable running and higher exhaust emissions.
• Incorrect fuelling can also affect catalytic converter life. If the engine operates excessively rich, unburned fuel can enter the exhaust system and cause the catalytic converter to operate at unusually high temperatures. Persistent problems may contribute to premature catalyst deterioration.
• A failed sensor can also cause the ECU to use substitute values or a fallback operating strategy. Although the engine may remain driveable, efficiency, emissions and performance can be compromised.
• Because 958906262G is specified for the right-side pre-catalytic converter position, correct sensor identification is particularly important when servicing engines with multiple exhaust banks and oxygen sensors.
• Replacing a defective sensor with the correct Porsche Right Lambda Oxygen Sensor 958906262G helps restore accurate mixture feedback, efficient combustion and dependable engine-management performance.

Diagram Ref No 7

Also referred to as a pre-cat, upstream or O2 sensor, the lambda sensor provides essential feedback to the engine control unit (ECU). By measuring residual oxygen in the exhaust gases, it allows the ECU to determine whether the engine is operating with a rich or lean mixture and adjust fuel delivery accordingly.

Because this sensor operates upstream of the catalytic converter, it has an important role in closed-loop fuel control. Accurate lambda readings help maintain the intended balance between engine performance, fuel economy and exhaust emissions while also helping protect the catalytic converter from the effects of incorrect fuelling.

Lambda sensors operate in an extremely demanding environment, continually exposed to high exhaust temperatures, vibration and combustion deposits. Over time, the sensing element can become contaminated or slow to respond, while the heater circuit, wiring or electrical connections may also deteriorate.

Replacing a faulty sensor with the correct Porsche Lambda Oxygen Sensor 958906262F helps restore accurate exhaust monitoring and proper engine-management operation.

What This Product Does:

• Measures oxygen content within the exhaust gases.
• Is designed for installation before the catalytic converter.
• Sends exhaust oxygen information to the ECU.
• Helps determine whether the engine is running rich or lean.
• Allows the ECU to make precise fuel-delivery corrections.
• Supports closed-loop air-fuel mixture control.
• Helps maintain efficient combustion.
• Supports smooth and responsive engine performance.
• Helps optimise fuel consumption.
• Contributes to correct exhaust emissions.
• Helps protect the catalytic converter from problems associated with incorrect fuelling.
• Provides the correct replacement for a worn, contaminated or failed sensor.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Lambda or oxygen sensor-related diagnostic fault codes.
• Rich or lean mixture fault codes.
• Increased fuel consumption.
• Rough or unstable idle.
• Hesitation during acceleration.
• Poor throttle response.
• Reduced engine performance.
• Engine running excessively rich or lean.
• Strong fuel smell from the exhaust.
• Increased exhaust emissions.
• Failed emissions testing where applicable.
• Intermittent engine-management warnings.
• Slow sensor response during diagnostic testing.
• Implausible or inconsistent lambda readings.
• Oxygen sensor heater circuit faults.
• Damaged wiring, insulation or electrical connectors.  

Why Replacement Matters:

• The lambda sensor positioned before the catalytic converter provides the ECU with important information for controlling the engine's air-fuel mixture.
• A healthy sensor reacts rapidly to changes in exhaust oxygen content, allowing the ECU to continually fine-tune fuel delivery. As a sensor ages, its response can become slower or less accurate even before complete failure occurs.
• Poor lambda feedback can result in higher fuel consumption, reduced performance, unstable running and increased emissions. The engine-management warning light may also illuminate when sensor readings move outside the expected range.
• Incorrect fuelling can have consequences beyond engine performance. An excessively rich mixture can allow unburned fuel to enter the exhaust system, potentially increasing catalytic converter temperatures and contributing to premature catalyst deterioration.
• A completely failed sensor may cause the ECU to substitute calculated values or adopt a fallback operating strategy. The engine may continue to run, but efficiency, emissions and performance can be compromised.
• Replacing a faulty unit with the correct Porsche Lambda Oxygen Sensor 958906262F helps restore accurate mixture feedback, efficient combustion and dependable engine-management performance.

Knock Sensor.
Restore accurate combustion monitoring and dependable engine management with this Porsche Knock Sensor, part number 95890537700. Designed for compatible Porsche applications, the knock sensor is an important part of the engine management system, detecting abnormal combustion vibrations and allowing the ECU to adjust ignition timing when necessary.  

Fits:

Diagram Ref No 21

During normal operation, the engine management system aims to achieve efficient combustion while protecting the engine from detonation, also known as engine knock or pinging. A knock sensor monitors characteristic vibrations within the engine and sends this information to the ECU. If knock is detected, the ECU can modify ignition timing and other applicable parameters to reduce potentially damaging combustion.

A faulty sensor can provide inaccurate information or no signal at all. The ECU may respond by using a more conservative engine strategy, potentially resulting in reduced performance, increased fuel consumption or an illuminated engine-management warning light.

The Porsche Knock Sensor 95890537700 provides the correct replacement solution for a failed or damaged sensor, helping restore accurate knock detection and proper engine-management operation.

What This Product Does:

• Detects vibrations associated with abnormal combustion or detonation.
• Sends knock information to the engine control unit.
• Allows the ECU to adjust ignition timing when knock is detected.
• Helps protect the engine from potentially harmful detonation.
• Supports optimum ignition timing under changing operating conditions.
• Helps the engine adapt to variations in load and operating conditions.
• Contributes to smooth and efficient combustion.
• Supports consistent engine performance.
• Helps maintain the intended balance between performance and engine protection.
• Replaces a failed, damaged or unreliable knock sensor.
• Restores correct input to the engine-management system.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Knock sensor-related diagnostic fault codes.
• Reduced engine power.
• Sluggish acceleration.
• Poor throttle response.
• Engine operating in a reduced-performance or protective strategy.
• Increased fuel consumption.
• Rough or inconsistent engine operation.
• Audible pinging or knocking under acceleration or load.
• Intermittent engine-management faults.
• Wiring or connector damage around the sensor.
• Diagnostic readings indicating an implausible or missing knock sensor signal.  

Why Replacement Matters:

• Detonation occurs when combustion within the cylinder does not proceed in the intended controlled manner. Instead, abnormal pressure waves can develop, producing the characteristic phenomenon known as engine knock.
• Persistent or severe knock can subject pistons, cylinder walls, bearings and other internal engine components to unusually high mechanical and thermal loads. The knock monitoring system helps protect against this by allowing the ECU to respond quickly when abnormal combustion is detected.
• If a knock sensor fails, the ECU may no longer receive reliable information about combustion vibration. Depending on the engine-management strategy, it may compensate by retarding ignition timing or otherwise restricting performance to provide a greater safety margin.
• This can result in noticeably reduced power or efficiency even though the engine continues to run.
• Conversely, an inaccurate sensor signal can interfere with the ECU's ability to optimise ignition timing correctly.
• Replacing a defective component with the correct Porsche Knock Sensor 95890537700 helps restore accurate combustion monitoring, appropriate ignition control and the engine protection strategy designed into the vehicle.

Diagram Ref No 7

The sensor is fitted at the brake pad and connected to the vehicle's electrical system. As the friction material wears down, the sensor eventually reaches the brake disc. This changes the sensor circuit and triggers a brake pad wear warning, alerting the driver that the pads require inspection and replacement.

Because a wear sensor can be physically worn through when activated, it will normally need to be replaced along with the brake pads once the warning threshold has been reached. Sensors can also become damaged during brake servicing or through deterioration of their wiring and connectors.

Using the correct Porsche 95B907637F Rear Brake Pad Wear Sensor helps maintain the functionality of the factory brake wear warning system and ensures the vehicle can accurately alert the driver when rear brake pad replacement is required.
What This Product Does:

• Monitors the wear condition of the rear brake pads.
• Provides an electrical signal to the vehicle's brake monitoring system.
• Helps trigger a warning when brake pads reach their specified wear threshold.
• Alerts the driver that brake inspection and servicing are required.
• Helps prevent brake pads being unknowingly used beyond their intended service limit.
• Connects the brake pad assembly to the vehicle's monitoring circuit.
• Supports correct operation of the factory brake wear warning system.
• Replaces a worn-through, damaged or defective sensor.
• Helps clear the brake wear warning once the brakes are correctly serviced, subject to the vehicle's reset procedure.
• Provides the correct Porsche replacement part for compatible applications.  

Symptoms Of Wear Or Failure:

• Brake pad wear warning displayed on the dashboard.
• Brake service warning remaining illuminated after new pads are fitted.
• Sensor tip visibly worn through. Damaged or broken sensor wiring.
• Cracked or deteriorated insulation. Damaged electrical connector.
• Wiring pulled away from its mounting points. Intermittent brake wear warning.
• Warning appearing despite adequate brake pad thickness.
• Sensor damaged during brake pad or disc replacement.
• Corrosion or contamination affecting the electrical connection.
• Diagnostic testing indicating a fault in the brake pad wear sensor circuit.  

Why Replacement Matters:

• The brake pad wear sensor provides an important early warning that the friction material is approaching its service limit. If the sensor is damaged or bypassed, the driver may lose this warning function.
• Continuing to drive after brake pads are excessively worn can eventually allow the pad backing material to contact the brake disc. This can significantly reduce braking performance and damage the discs, increasing the extent and cost of the required repair.
• Once a wear sensor has contacted the brake disc and activated the warning, the sensor itself may be physically worn and cannot simply be reused with new pads. Installing a replacement sensor during the brake service restores the monitoring circuit for the new brake pads.
• Damaged wiring can also produce persistent or intermittent dashboard warnings even when the pads are in good condition.
• Replacing a worn or defective sensor with the correct Porsche Rear Brake Pad Wear Sensor 95B907637F helps restore reliable brake wear monitoring and ensures the vehicle can provide the intended warning when future brake service becomes necessary.

Diagram Ref No 1

When the vehicle is started, the starter motor draws electrical power from the battery and uses an internal electric motor and solenoid mechanism to engage with the engine's flywheel or flexplate. This rotates the crankshaft until the engine starts and can operate independently. Built to withstand high electrical loads, repeated starting cycles, vibration, and demanding engine-bay temperatures, this Genuine Porsche starter motor is an ideal replacement for a slow, intermittent, noisy, or completely failed unit.  

What This Product Does:

• Cranks the engine during the starting process.
• Converts battery electrical energy into mechanical rotation.
• Provides the torque required to turn the engine crankshaft.
• Engages with the flywheel or flexplate during starting.
• Supports fast and dependable engine starting.
• Disengages once the engine has started.
• Replaces a weak, intermittent, noisy, or failed starter motor.

Symptoms Of Wear Or Failure:

• Engine failing to crank when attempting to start.
• Slow or laboured engine cranking.
• Intermittent starting problems.
• Clicking sound when the starter is activated but the engine does not turn.
• Grinding or unusual noises during starting.
• Starter motor spinning without properly engaging the engine.
• Engine requiring repeated attempts before it starts.
• Starter remaining engaged briefly after the engine starts.
• Burning smell or signs of excessive heat around the starter circuit.
• Starting problems despite a correctly charged and serviceable battery.

Why Replacement Matters:

• The starter motor is essential for reliable vehicle operation because it provides the initial mechanical rotation required to start the engine. A worn starter motor may crank the engine too slowly, operate intermittently, or fail completely, potentially leaving the vehicle unable to start.
• Internal wear to the starter motor, solenoid, bearings, brushes, or engagement mechanism can also cause clicking, grinding, or inconsistent operation. Continued use of a failing starter may place additional strain on the battery and electrical connections, while an engagement fault can potentially damage the starter pinion or flywheel/flexplate ring gear.
• Replacing a worn or failed unit with this Genuine Porsche Starter Motor 95860410900 restores strong and consistent engine cranking, improves starting reliability, and maintains the vehicle's original factory functionality. Manufactured to Porsche's exacting standards, this genuine component provides precise fit, correct electrical performance, dependable operation, and long-term durability for Porsche maintenance and repair.

Why Replacement Matters:

• The alternator is a critical component of the vehicle's electrical and charging system. Once the engine is running, it supplies the electrical energy required by the vehicle while replenishing the battery after starting. If alternator output becomes insufficient or unstable, the battery can gradually discharge and sensitive electronic systems may no longer receive the consistent electrical supply required for correct operation.
• A deteriorating alternator can cause starting difficulties, charging warnings, flickering lights, intermittent electrical faults, and unreliable operation of vehicle electronics. If the alternator stops charging completely, the vehicle will continue operating only while sufficient battery energy remains, eventually resulting in the engine shutting down and being unable to restart.
• Mechanical alternator problems, including worn bearings or pulley-related faults, can also produce excessive noise and may place additional strain on the auxiliary drive system if left unresolved.
• Replacing a worn or failed unit with this Genuine Porsche Alternator 976903024D restores dependable battery charging, maintains stable electrical output, and supports reliable operation of the vehicle's electrical systems. Manufactured to Porsche's exacting standards, this genuine component provides precise fit, correct electrical compatibility, dependable performance, and long-term durability for Porsche maintenance and repair.
