Audi A8 D3 4.2fsi - Suspension adaptation - the rear dropped during adaptation

I have a problem with adapting the suspension in the 2007 Audi A8 4.2fsi.

During the adaptation of the suspension after the start of the adaptation in channel 01, when it displays "wait", the rear of the car fell down and it does not rise .. I waited several minutes but I kept waiting and the suspension is standing.

When I raise the rear - with the pumping procedure in basic settings and align with the front based on the pressure - the adaptation procedure starts again but the rear of the car drops again. I also did a factory reset. But the situation is impossible. There is one error -01437 but understandable because the procedure is started but the suspension has not been adapted. Please help

The compressor doesn't work. Common malfunction.

Thanks for the hint. Because actually pumping is suspicious for me.

Say whether in the pumping procedure. I am doing vcds, so login 08367 and basic settings of groups 24 and 25 and then the compressor pumps up to a certain point and stops. You have to turn off the ignition and restart the procedure and continue to pump. Is this normal or should I pump all the way ?? Ps the battery voltage is correct.

He's pumping all the time. There is a temperature sensor in the compressor and the compressor turns off at the set temperature.

New compressor, ie after regeneration .. then the same .. some idea what next ??

But what is pumping all the time or not, have you checked if it has power?

Disconnect the clamp for testing or leakage in the system. Are you sure about this compressor?

After a few more attempts from installing the new compressor, the adaptation was successful, but in this way: I started in the 1st channel, I entered the measured value and left the adaptation completely, later 2nd circle and the same 3rd and 4th, then I saved the 5th channel and it worked. Weird, but that's the way it's great now. The car is finally standing as it should. Thanks for the advice.
