Compressor air conditioning failure on Peugeot e-208, e-2008, and Opel Mokka-e (9840056680 / 9831370080)
On the Peugeot e-208, e-2008, and Opel Mokka-e, the high-voltage air conditioning compressor is not only used to cool the cabin. It also plays a role in the thermal management of the traction battery, which is essential for the vehicle’s proper operation. When it fails, passenger comfort, charging performance, and in some cases even vehicle usability can be affected.
What is the role of the high-voltage compressor?
Unlike an internal combustion engine vehicle, the compressor is driven by an electric motor powered by high voltage. On models equipped with the Valeo references 9840056680 and 9831370080, it provides:
- Cabin cooling.
- Thermal management of the battery during driving and fast charging.
A failure can therefore affect both the air conditioning system and the vehicle’s energy management.
Symptoms of a faulty compressor.
The failures observed in the workshop generally result in:
- No cooling in the cabin.
- Difficulty or inability to initiate fast charging.
- The appearance of air conditioning or high-voltage related fault codes.
- Communication errors on the vehicle network.
- Abnormal noises coming from the compressor.
Checks to perform before diagnosis.
Before blaming the compressor, it is recommended to check:
- The refrigerant charge and the system for leaks.
- The fuses, 12 V power supplies, and ground connections.
- The LIN/CAN communication networks.
- Compliance with the vehicle power-down procedure before any intervention.
If these checks are satisfactory but the faults persist, an internal compressor failure becomes likely.
A repair reserved for specialists.
High-voltage compressors are sealed assemblies that integrate power electronics. They must never be opened or disassembled in the workshop. Any attempt to open them may compromise their integrity and void the warranty conditions.

Why choose repair?
This solution allows you to:
- Reduce the cost of restoring the vehicle to working condition.
- Minimize vehicle downtime.
- Preserve the original part.
- Reduce environmental impact.
- Benefit from a 2-year warranty.
What should be checked before sending the compressor for repair?
Before shipment, it is recommended to check the refrigerant charge, the system’s leak-tightness, the fuses, the 12 V power supplies, the ground connections, as well as the LIN/CAN communication networks.
What does fault code P2C87 on the air conditioning compressor mean?
The P2C87 fault code may indicate an internal resistance issue within the high-voltage compressor. When this fault remains present after checking the power supplies, wiring, and air conditioning circuit, it may reveal an internal compressor failure. A bench test can then be carried out to confirm the fault before remanufacturing.
