Warranty only if a new relay is used!
The relay must be replaced at the same time as the compressor is changed.

Before purchasing a compressor, please consider the following:
The most common reason for a faulty compressor is a leak in the system, causing the compressor to run too long and too often.
A disproportionate number of switch-on cycles lead to the relay contacts sticking together.
This means that the relay no longer has any function.
The result is continuous current on the compressor.
The compressor runs continuously without control until it burns out.
Before a new compressor is installed, all reasons why it was damaged must have been completely eliminated.

Regarding the leak:
A leak can occur in many places, such as:
- Porous or damaged air springs
- Worn seals, defective compressed air connections and chafed compressed air hoses
- Leaking components such as compressors, valves and air springs

Every air suspension system is vulnerable in this way.
Therefore, follow our advice to avoid having to face further repairs in the near future.

Basic advantages why you are in good hands with Miessler Automotive® when it comes to air suspension:

- More and more own products that make repairing your vehicle easier
- Repair service in our own specialist workshop

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 replacing 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 and wait for the system to automatically adjust (if your vehicle has this feature). Accurately measure and note all heights that are air-assisted, 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 parked overnight, a compressor should not run for more than 20 to 30 seconds until the system is ready to start again.
