Our technical advice for air supply:
1. An increased running noise of the compressor is often caused by the suspension of the compressor no longer functioning.
Be sure to also change the suspension rubbers and springs.
2. A porous intake hose is often the cause of compressor failure.
Change this and, ideally, the filter/noise damper at the same time.
We don't want the new compressor to fail prematurely for this reason.
3. Change the working relay before installing the compressor, even if it still appears to be functional.
This is also a mandatory requirement of the car manufacturer.
Make sure you are changing the correct relay. Relays are similar. There is a great risk of having replaced the wrong relay.
4. After the repair, make sure that the system is absolutely tight.
The easiest way to determine this is to park the vehicle. Wait for the system to automatically readjust if your vehicle has this function. All heights that air supports must be precisely measured and noted from the ground to the bottom edge of the fender. The next day check and compare these heights.
Even a small deviation in the distances leads to long-term damage to the compressor and the valves.
If you have been driving for some time with a leaky undercarriage, it can be assumed that the compressor is running more often than normal. This increased number of on and off cycles may have already damaged the compressor. Depending on how long this condition has lasted, you should change the relay as a precaution and check the compressor's performance. After the car has been left overnight, a compressor should not run for more than 20 to 30 seconds until the system is ready to start again.
Installation and expansion may only be carried out by trained personnel in a specialist workshop.
