Slipping Clutch?

[Grimlock85]

I need help!

I've got a 2011 135 6MT with a BMW PPK1. So i'm not making tons of hp/tq, it's all within stock specs. I'm getting a strange vibration/stutter when taking off in 1st gear. It ONLY happens in first gear taking off from a standstill and happens more often in the afternoon (hotter weather). The best way to describe it is that it feels like my tires are breaking traction before taking off. I've got brand spanking new tires less than 3k miles ago and i've got a CDV valve delete. The only conclusion I can come to is that it is my clutch, but its not exhibiting the classic clutch slipping characteristics. There's no jump in rpm when I get on it in any other gear. It's only got 45k miles, so i'm finding it very very hard to believe that it's the clutch, all my previous cars have used original clutches way beyond 100k. So i know it's not my driving style or habit. I simply cannot identify what the problem likely is. I took it into the dealership and they could not identify anything wrong with it. I replaced the plugs/coils at 40k, so they should be good too.

Any thoughts would be a great help! I hate to have to keep bringing it into shops and paying $$ for diagnostics. Oh, and also there are zero misfires

Are you already fully clutch out at this point? If not, see below:

Give it more gas. I know that sounds overly simple or condescending, but seriously, when you let the clutch out, give it more gas.

oh, i should of specified a bit more. It's in the process of engaging and i'm pushing the gas hard, not WOT. But an aggressive take off. pedals probably down half way, more than enough to get the car going. Put it this way, its the type of acceleration you'd do at a red light if you wanna get in front of the car next to you since your lane is ending, for example.

Yup, clutch chatter. Very common. Although, installing the M3 RSFB's made it better for me. Just have to be careful modulating the clutch and I never feel it anymore.

[edisapimp]

worst case scenario it's a case of an out of balance or poorly surfaced flywheel.

[Grimlock85]

I'd like to get rid of it completely as it is extremely anoying when driving. Sounds like i'll need to replace my flywheel and clutch? Any idea how much that'll run me?

Thanks for the responses

If you have to ask how much it costs, don't go in there unless you need to.
