2015 Q50S noise?

Postby rcrisp » Wed Jun 24, 2020 9:43 am

Over the COVID break my Q50S sat and was only driven a few miles a week for 8-10 weeks. Since that break I now have a strange howling like noise coming from the engine. It is most pronouned at idle. It does not change if I shift throughin PRND or turn steering wheel. As I accelerate I can't tell if it goes away or is simply drown out in the engine noise. I have used a stethoscope to probe everything I can imagine and can't locate where it is coming from. Does anyone have any ideas what the cause could be. My guess is power steering pump or AC compressor but the stethoscope is quiet when I probe those.

Video with the issue? The only issue I've had with my '14 Q50s is with a rattle that ended up being one of the straps that hold the heat shield to the y-pipe being rusted through but no howling noise.
