Air suspension sounds
Quick question to all those with a D3. Had the compressor rebuilt three weeks ago.
If you drive along normally with the radio off, and the air compressor runs when it switches off mine seems to make a very audible pssch sound which you can hear from in the cabin. You don't hear it with the radio on since the audio drowns out the sound. I also dont recall ever hearing the car level out when removing a heavy object, which I can hear now (its a controlled ssshhh for 2 or 3 seconds) which stops suddenly when the valve closes. The guy that rebuilt the compressor and refitted has had the car back and says it looks ok, but I am not so sure. I do wonder if the vent/intake pipe has come loose or detached. its all working fine functionally, but I don't want the compressor to be breathing bad air if something has come off. I can access the area of the compressor, I was in there on Sunday trying to find the parking sensor wiring. I don't know how the compressor is orientated and thus where to find the vent pipe. I've started to build a relationship with another specialist, so may seek a second opinion.
