Rattle when car is in reverse?

marwin888 · 03-01-2021, 04:06 AM

Hey guys,

So I had a question about a rattle noise my car is making. First off I have a 2013 335i 6 spd. Few mods I have are the DINAN stage 2 with the MPPK plus M performance exhaust. Anyways I noticed during cold start that my car is making a rattle noise when the car is in reverse coming out of my driveway. After driving, whenever I reverse the noise goes away from what I can tell. It seems like it's coming from the rear right tire but not sure. I checked the brake pads and they look fine. I can be coming off my driveway in reverse or in neutral but it still makes that noise when the car is in reverse motion. It doesn't matter if it is in gear or not. I pasted a link below to see if this sounds familiar to you guys.

Any help is appreciated!!

It does not happen when I'm moving forward. It seems to only happen when the car is in reverse motion. It has 105k miles

So this sounds like it is something that is not directly related to wheel/driveshaft speed. To me it sounds like metal vibrating against another thin metal. Its strange it only happens when moving backwards. I would get the car in the air and start tapping on any thin metal pieces and check for contact where there shouldnt be... heat shields, brake/wheel area, etc.
