Weird noise while accelerating *video included* HELP!

M3_Slayer · 09-01-2023, 02:02 AM

Hey guys,

I started hearing this noise while driving the car today. Not sure how to describe it... rattle noise? Sounds like a plastic object got stuck somewhere in the engine. I can only hear it in the cabin while accelerating. The car sounds fine from the outside with the windows down when the car is in motion. Has anyone experience this sound before? Your feedback is appreciated!

Maybe something got caught up under the car.

Underneath seems fine. Checked underneath the hood also nothing looks loose.

check heat shields underneath the car, around the trans and driveshaft

I would check the driveshaft center support bearing.

Thanks for the feedbacks. I’ll have it checked out at ACM. Do you think it’s safe to drive the car? I’m pretty far from the shop
