What year is your car ? And curious to your power numbers as well as mileage .. also X drive ? … For the clunk and whining noise is kinda strange ..
2020 M340I RWD. 41K miles as it sits. DP + E85 tune power numbers are supposed to be high 4's to low 5's never been on dyno. I have noticed the seeping residue on diff since early on into ownership. Now has dried up into a thick grease like residue leak doesn't seem to be active anymore. I think it leaked out to the point where it's not active anymore almost as if not enough diff fluid inside lol if that makes sense. After looking up part number this cover is cheap enough that I can finish the job at a independent place and not risk getting locked at dealer. The clunk is only taking off from a complete stop at low speeds up to only a few miles an hour. Goes away when warmed up along with the whine. Will keep it updated.
