Rattling Noise under acceleration.

Apologies posted this in the wrong section initially.

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.

Also thought it could be a weird implementation of active sound.

anyone have any thoughts on what it could be?

Definitely not normal. There shouldn’t be any rattling or noise going through any of the gears

I would check the exhaust hangers. Could be that the exhaust is loose.
