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 or air spring components (suspension strut)
- Worn seals, defective compressed air connections and chafed compressed air hoses
- Leaky housings in components such as compressors, valves, air springs or suspension struts.
.
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:
- We have been dealing with this issue since 2003
- Manufacturers selected by us are one of the pillars of the best quality
- Close cooperation with manufacturers in the area of quality management
- 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.

Before purchasing a compressor, please note the following:
Most common reasons for a defective compressor is a leak in the System and also a defective relay.
An excessive number of switch-on cycles will cause the relay contacts to stick together.
The result is continuous current on the compressor.
The compressor runs continuously without control until it burns out.

Another main reason why the compressor stops working is moisture inside the compressor.
This happens insidiously via leaks such as:
- Porous or damaged air springs or air spring parts (strut)
- Worn seals, defective compressed air connections and chafed compressed air hoses
- Leaking housings in components such as compressors, valves, air springs or struts.

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

Before a new compressor is installed, all the reasons why it has been damaged must be completely eliminated.

Our technical advise for the air supply device:
1. Change the relay before installing the compressor even if it seems to still work.
This is also a specification by the car manufacturer. Be sure to change the right relays.
Relays look similar, that is why there is a risk to change the wrong relays.
2. Be sure to check whether the system is leakproof after repairing.
The easiest way to do this is to park the vehicle. Wait for the system to automatically re-adjust if your car has this feature.
Then measure the heights from the ground to the lower edge of the fender as exactly as possible and take notes.
On the day after measure these heights again and compare them with the ones before.
Even a small difference will lead to a damaged compressor and damaged valves in the long run.

When driving with a leaking suspension for a long time it needs to be assumed that the compressor is running more often than normal.
The increased number of cycles of powering on and off is likely to already have damaged the compressor.
Depending on the duration of that condition you should change the relay and check the performance of the compressor to be on the safe side.
After the vehicle stood overnight the compressor normally doesn't need to run more than 20 to 30 seconds for the system to be ready to start.
