Good day I saw your videos of how you deal with the airmatic chassis. I recently bought a crashed GLE coupe w167, where the airmatic compressor was missing. I bought a second-hand compressor from exactly the same car and installed it in my car... After connecting to the diagnostics, I can't start the compressor... It doesn't respond... The diagnostics tells me an internal compressor error... it can't even be started manually through diagnostics... I've already checked all the wiring... I've replaced the compressor relay... I've checked the fuses... The compressor still won't start Could you advise me where the error could be? Does this compressor have a control unit in it that is foreign to this car if it is not from the same car? Thank you for your reply
