Rattling Noise Under Acceleration

numbercandy · 02-25-2023, 03:18 PM

Hi all

Recently purchased an approved used M2c 2020, low miles (under 5k).

Have noticed a faint rattling noise can be heard in the cabin. goes up and down entirely in relation to the revs of the car (and general exhaust noise).

Have looked at a lot of threads here and initially thought it was DI noise, but it still makes a similar noise when downshifting and the revs climb. Almost sounds like a vibration somewhere but have looked to isolate with no luck.

anyone have any thoughts on what it could be?

Go ahead and make a third thread in the S55 engine / exhaust / tuning section to round out the spam job.

No half-steppin.
