FAQs
Is this a direct fit for my car?
This pump is compatible with BMW 5 Series G31 and 6 Series G32 models matching part number 37206886721.
Do I need to replace the relay?
Yes, it is highly recommended to replace the suspension relay during installation to prevent the new pump from burning out due to a faulty or stuck electrical relay.
Can I install this at home?
If you are experienced with automotive repairs, you can install it yourself, but you will need access to diagnostic software to clear the suspension fault codes.
Why is the compressor running constantly?
If the compressor runs for long periods, it is likely compensating for an air leak in the system, typically in the air bags or pneumatic lines.
What tools are required?
Standard metric socket set, a vehicle lift or floor jacks, and a BMW-compatible diagnostic scan tool for post-installation setup.
Troubleshooting
Compressor fails to activate
Check the suspension system relay and associated fuses. Ensure the electrical connector is fully seated.
Vehicle still saggy after install
Check for air leaks in the air bags or the distribution valve block, as a new pump cannot maintain pressure if there is a downstream leak.
Warning light remains on dashboard
Use a specialized BMW diagnostic scanner to clear the stored fault codes and calibrate the ride height sensors.

Setup, Compatibility & Care
Compatibility: This unit is exclusively designed for the BMW 5 Series G31 (Touring) and 6 Series G32 (Gran Turismo) models.
Setup: Installation involves removing the underbody shielding, disconnecting the air supply lines, and unplugging the electronic harness. Always replace the relay when installing a new compressor to ensure the electrical circuit is fresh and capable of drawing the necessary current.
Care: To prolong the life of your new D2P compressor, avoid over-loading the vehicle beyond its weight limits. Periodically check for moisture in the air lines, as excess water can cause internal corrosion to the pump head or cause the system to freeze in cold climates.
