Hey everyone, my 2008 335i has recently developed a strange clunk. The noise is only present at low rpm <1800. It makes a single clunk when putting the engine under load. I'm leaning towards it being the stock dual mass flywheel as it has 90k on it. And it sounds like it's coming from in front of the shifter.

Yeah I can't feel anything, it just sounds like it's coming from in front of me. That's why I was originally thinking flywheel. Also if I hit the clutch in and back out it will make the noise everytime. My biggest worry was it being something in the engine. I read a forum post from an m3 owner complaining about a similar sound, or at least similar conditions to cause the sound as he didn't post a video. Apparently it ended up being early rod knock.

does it have a light rattle at idle and push clutch in goes away? that how both my dmf failed (internal damper), could be urs is worse than my experience. more of a click/clank imo so there will be witness marks of the 2 parts touch, i would try a shop lift and hope it does it in the air with no load

I cant tell the noise from the video but does it sound like this? is it a noise that sounds like something moving back and fourth a bit? This is what I have when I abruptly disengage the clutch at low RPMs and usually first gear. Not a helpful response but I have been struggling to find what it is as well. |
