I recently noticed that upon a quick takeoff, I can hear and feel a bit of a vibration. It's kind of like a squeaky hum. (kinda tickles the nads a bit ;D) At first I thought it was my rear brake catching, so I did it a couple more times. It happens just as the clutch is disengaging. I'm not excessivley clutching upon the launch, I was getting clean takeoffs. I was wondering if anyone has experienced this before...

If it's a kind of groaning sound/feeling as the clutch is almost solidly engaged, it's the clutch. Mine does it occasionally whether it's clean or dusty inside - but it's on its last legs at 15K miles. I've seen other posters report the same sound on realtivley new clutches too.

the wet clutches do it to.
no problem.
just clutch plates starting to grab.

I got that too on my M900. Drove me nuts so I asked around and was told that I could try and remove the pressure plate, carefully remove the clutch plates, lightly sand, and reinstall. It worked like a charm and took only 20 minutes, not more of that weird vibration/studdering at a start. By the way, there is more to removing the clutch plates than I've indicated. Do a search as i'm sure someone has describe it very well in the past.

By the way, THIS IS ONLY FOR DRY CLUTCH MODELS!!!!

Miles, what exactly are you supposed to sand? The clutch plates? And just enough to rough them up a bit?

I get that same thing on my 01 s4, so basically I should continue not paying attn to it? I may try sanding down the clutch plates. Does anyone have a picture of what they should look like after a light sanding?

They won't look any different really. I think all I did was scuff off the glaze that had formed and was causing the plates to stick. In fact, halfway through sanding I got discouraged and figured I wasn't having any effect. I continued anyway and reinstalled everything. To my surprise it proved to be 100% better.

Sorry meds1, I didn't reply to your question. Yes, just scuff each plate lightly. I used a real fine grit paper went over each side of every plate. Honestly the plates really looked no different before or after which is why I felt like I wasn't doing anything. Someone else who has done this care to offer their experience? It could be that experience was not typical! Anyway, give it a try since it's pretty fast and simple. You really have nothing to loose.
