Hi all,

I have a 2007 BMW e60 530xi. It’s been pretty good since I got it three years back. However, it’s been starting to give some trouble, but it has also just reached over 400,000kms so I don’t think I should be expecting too much from it lol.

I have an issue with my car which is a thumping like sound that seems to be coming from the back of the car upon low acceleration. It goes away once I go above like 20km/hour but under that it thumps. Typically in residential areas where i’m driving slowly (not coasting). I’m not sure what this is and was wondering if anyone has experience with an issue like this before I take it to a mechanic. Any advice would be appreciated

Edit; I also have my abs, dsc, awd lights on in my car. I initially thought it was because of my wheel speed sensors or my axel (which the rubber boot part was ripped and i replaced the whole axle) but after changing those the lights are still on.

It could be so many things:

1. Tires
2. Wheels
3. Wheel Bearings
4. Rotors
5. Brakes
6. Etc, etc.

Or it could be in the front which has even more possibilities.

My bet is it's rear differential mounts / bushings or possibly center support bearing noise. Or flex discs. Could be sway bar links or bushings. And don't laugh - it could be loose rubber exhaust mounts (mine would oscillate at certain speeds - ran me crazy trying to find that one).
