N55 Strange Noise?

st0nge · 09-20-2023, 05:30 PM

Any ideas on this noise at idle and while driving? It follows the RPMs, at idle it sounds more like a constant fainter drumming noise, and also like this. Pushing clutch in does not change noise. recently had ac compressor replaced due to faulty pulley, and new belt and other pulleys done a few months back. Car runs strong, no codes. More apparent in cabin then under hood. wastegate solenoid?
