Hi

Some strange problem exists with my EAS at the moment.

During the time the car is parked it will gradually lower the car to the bump stops. At first I tought a leaking spring, air line or valve block but could not find any leak. Reservoir pressure remains at 10 bar.
Then I took out the eas timer 15 minutes after the car was parked and cooled down. The next morning the car was at the same height as when I left it with the timer unplugged. Plugged the relay back in and read and cleared the fault codes and all was well for the day but the next day again lowered car overnight.
Checked the ECU memory: No faults.

Because of this behavior every morning we have to give time to the EAS system to pump back the pressure into the tank. The moment you start it will self level and the car comes up but there is not enough air pressure to lift it up completly (The tank pressure drops from 10 to 5 bar) and the light keeps blinking. If you open a door and wait for the compressor to refill the tank to 10 bar the car self levels and all problems are gone for that day. It looks like the springs are completly deflating overnight without any pressure left in them.

Anybody came across this behavior? What did you do to solve this problem?

Regards

Jos

Height sensor calibration, you've got one or more that the values have changed (will happen over time, normal age) or is dying. It will lower itself to find level, and keep going down till to access. if the value for access height is BELOW the value the bumpstops are actually at, it will continue to release air trying to get it down untill there is no air left.

Hi

Thanks Dennis for the advice.

Monitored sensor position read outs for a while and indeed left fwd sensor was suddenly jumping from a hundred to 4 and back to hundred. Changed the sensor 3 days ago and now it stays levelled again.

Also found leak at the top of right air spring. The plastic tube was pulling at it under an angle. Replaced part of the tube.

Hopefully no more EAs troubles in the near future.

Regards

Jos
