I have a 2014 500L trekking every time I turn on the AC a very loud knocking noise comes from under the hood I don't know if it's a thermostat housing or the compressor does anybody else have this

What did you find out with this? I have same issue with a 2014 500L. Appears to be coming from compressor when clutch is engaged.

A sound clip? The compressor engaging. Run it by a AC shop for a diagnostic.
