What This Product Does
The compressor pressurises refrigerant and moves it around the air conditioning circuit. Working with the condenser and evaporator, it enables the system to remove heat from cabin air. Reduced compressor output can therefore affect cooling even when the ventilation fan still operates normally.
Functions
- Compresses refrigerant gas within the A/C circuit.
- Maintains refrigerant circulation through the cooling components.
- Supports cabin cooling and air conditioning operation.
Technical Details
- Compressor part number: 95812601301.
- Additional supplied reference numbers: 95812601112, 928126013AX, 95812601300 and 95512601112. Confirm the applicable reference for your vehicle.
- 957 diagram application: PR:D50.
- 958 diagram application up to 2016: Diesel, PR:D50,D51,D43,D1V,DV7.
- 958 diagram application from 2017: V6 TDI, PR:D43,DV7,D1V,D50,D51.
- The 2017 onwards diagram specifies PR:KK1,-D19 and identifies PR:KK1 as refrigerant R134a.
Symptoms of Fault
- Vent air remains warm or cooling becomes inconsistent.
- Rattling or knocking is heard around the compressor.
- Refrigerant or oil leakage is visible.
- System pressure checks indicate inadequate compressor output.
Why Replacement Matters
A compressor that leaks, seizes or cannot generate the required pressure may need replacement to restore cabin cooling. Diagnosis should establish the cause first: low refrigerant, inadequate lubrication, contamination or restrictions elsewhere in the circuit can produce similar symptoms or contribute to compressor damage. Internal wear can also introduce debris, so the repair should address the condition of the complete circuit rather than the compressor alone.
FAQs
- Will regassing resolve weak cooling?
It may help when refrigerant is low, but recurring refrigerant loss requires leak diagnosis. Regassing does not repair mechanical compressor damage. - Should the drier and system cleanliness be checked?
Yes, particularly following internal compressor failure. Assess drier replacement and cleaning requirements as part of the repair. - What about compressor oil?
The oil specification and total quantity must suit the vehicle and repair. Check these requirements before installation rather than assuming the supplied oil charge is sufficient. - How should compatibility be confirmed?
Match the vehicle's model, engine, production year, PR codes and original compressor reference before fitting.

As the heart of the air conditioning system, the compressor is responsible for circulating refrigerant throughout the system. Replacing a worn or failed compressor restores cooling performance and ensures the complete air conditioning system operates efficiently.
What Does the Air Conditioning Compressor Do?
The air conditioning compressor is the primary mechanical component of the A/C system. Driven by the engine via the auxiliary drive belt, it compresses and circulates refrigerant through the condenser, receiver dryer, expansion valve and evaporator.
Its primary functions include:
- Compressing and circulating refrigerant throughout the air conditioning system.
- Providing cold air to the passenger compartment.
- Supporting rapid cabin cooling.
- Assisting with windscreen demisting and dehumidification.
- Maintaining efficient climate control performance.
- Helping improve passenger comfort in all driving conditions.
A correctly functioning compressor is essential for effective air conditioning performance.
Why Do Air Conditioning Compressors Fail?
Air conditioning compressors are subject to continual
operation, high pressures and temperature changes. Common causes of failure
include:
- Internal bearing wear.
- Compressor clutch failure.
- Lack of refrigerant lubrication.
- Internal piston or vane wear.
- Moisture contamination within the system.
- Debris from previous compressor failures.
- Seized compressor due to prolonged inactivity.
- High mileage and normal wear.
As the compressor deteriorates, cooling performance reduces and additional strain may be placed on the rest of the air conditioning system.
When Should the Air Conditioning Compressor Be Replaced?
Replacement is recommended if you experience:
- Warm air from the air conditioning vents.
- Excessive noise from the compressor.
- Compressor clutch failure.
- Refrigerant circulation problems.
- Seized or locked compressor.
- Metal debris found within the A/C system.
- Poor air conditioning performance despite correct refrigerant charge.
Whenever a compressor is replaced, Porsche specialists also recommend inspecting or replacing the receiver dryer, flushing the air conditioning system and fitting new seals where required to maximise the life of the new compressor.
