Reverse clunk noise
Was wondering what this could be... sounds odd..
its on the e46, 2002 (about 150,000 km)... its automatic..
So it sometimes happen if im in park, or drive, and i put it into reverse, as i let go off brake itll make like a clunk in the back , kinda loud actually..
what could it be?

If it was an E34 I'd say torn subframe bushings. With an E46, I wonder if it's the torn subframe mount sheetmetal issue everyone talks about...

I had the exact same issue, but for me it happened occasionaly and only when putting it into reverse (when the car squats), would I hear a loud clunk from the back. It ended up being the rear springs, they were cracked (a pretty common issue on e46's). Good luck.

Lol my rear springs cracked at around ~55,000km (have the invoice somewhere, but around 50-60k). Could be, check it out.
Otherwise, as the previous poster mentioned, might be some sort of bushings (usually good to check all the bushings on these cars  ).

I have the same issue. I thought it was the rear springs, but those are fine. I'm currently looking into this whole subframe issue and if a problem exists, I'm curious to see how the car drives after it is fixed. Would you be able to notice a difference in the drive quality? I would assume so since the car does have a few clunks and bangs here and there during regular use...maybe it's just a dodgy subframe which needs reinforcement.

sounds like it could also be a subframe crack.. your best bet is to have it hoisted up and checked...

all above things are posible, but could also be something to do with the driveshaft, when you put it in gear, the tranny loads, but the drive shaft is held in place by the brakes. when you let off the brakes power is transphered to the shaft, and slack in the U-joints or possible worn flex disk/and or/center bearing will then be loaded and cause a clunk.
its not so noticable with manual cars as automatics
