Ok, so these weird noises that I have heard have been addressed without success (previous thread).
An MB tech is coming in on Thursday 10/15 to see what's up. So far they have replaced: a/c compressor pulley, power steering high pressure hose, internal fan blower motor (this problem was fixed - what a miracle!).
The service rep took my har home and agreed with me about the noises. He ordered a new high pressure hose. The problems persisted.
The shop foreman took my car home and back and described the noises as "normal". I had a 2009 ML350 that was as quiet as a church mouse. The shop foreman said different components. Not sure I believe him...
My service rep argued with him until he agreed to have an MB tech look at the car. Ugh, so far my experience with this vehicle has been less than adequate.
As a recap, the noises are:
1) When the car is warm, at idle with drive engaged, foot on brake, you hear a chirping noise that fluctuates when you move the steering wheel... I suggested a new power steering pump - they replaced a hose.
2) While driving at low RPMs, low speed (2000 rpm, 10 - 30 mph) the typical whining noise of the transmission is exacerbated when the a/c compressor kicks on. It becomes a terrible whining noise... I suggested a new compressor - they said no.
If anyone has had similar expriences I would love to know.
