-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.
