that is great news. if you have to replace the clutches, it's not cheap.

You mean without the slip is good? I thought it is DCT feature, it's should be there

I own the car for 2 year, low mil 2011, now it's have 26k on it. When it is all sotck, the slip always there, I think the slip was gone at that time I installed MS catless xpipe and ESS tunning for remove CEL.

Are you running a JB4?

No sir, I am running on ESS TUNE and baisicly it is for turn off CEL of catless xpipe.

I've used the Schwaben BMW scanner to perform the clutch adaption routine. My clutches were not slipping. I just did it as general maintenance.

The Schwaben scanner will do a lot of other stuff for your M3 like read and clear codes. It's made by Foxwell. I spent $60 on Foxwell's website to get the GM config pack so I can use the scanner on my wife's Chevy Traverse.

Did you notice any changes after the re-adaption took place? I'm just wondering what one could expect after doing this? I sometimes get slight lag between 2nd and 3rd gear shifts at 8300-8400 RPM.

The shifts seemed a little smoother when driving chill, but that could just be a placebo effect.

That tool will likely only reset adaptation not reset clutches. You need a dealer gt1 to reset for the thick was of the clutches not just your shitty driving habits.

Please elaborate on what is the difference between the adaption and other reset you mention.

are you in auto mod and when you press the gas aggressively the slip occurs then?

the reason i ask is, I believe the worse thing an owner can do to the dct is
1)hold the left paddle and floor it for optimum gear choice
2)in auto mode, floor the gas at cruising speed and let the trans choose the gear.

that massive clutch slips is what I believe is the culprit to my methronics failure (I have another theory but don't have evidence for for).

if you've done 1) or 2) often with the 650 you've burned your clutches or have overheated the metronics system and damaged it. it will not get better with re-adapting the clutches. ask me how i konw.

Whats the other theory?

The shwaban and my ess software/ other tunes just reset how the transmission adapts to your driving, e.g. how soft or hard it shifts. The other actually uses a bmw computer with icon most cable which checks the thicknesses of the clutches and adjusts the entire transmissions spec to the current thickness. This gets rid of slip. It theres slup after that you need new clutches. The former just makes it shift differently based on if you've been driving it like grandma and the dct adjusted to your laziness.

There is SO MUCH false information in this thread. IF you are supercharged and you are experiencing clutch slip, the clutches are already toast. There is no adaptation reset or clutch adjustment that is going to fix this issue. It's a mechanical slip problem. Not a hydraulic line pressure problem or a mechanics problem. You are mechanically exceeding the torque holding capability of your DCT clutch packs. 100%. You will have to replace with a new stock clutch pack and drum, OR upgrade to something more durable to avoid having this problem again. Either way it's going to be 5 grand plus or minus.

Untrue. I know a few people that have reset the clutches and the minor slip went away. Also the clutches themselves from don't cost 5k.

Unless you have the specialty tools from BMW you can't do this job DIY. The install/ removal tool just to get the drum out is $900.

Thanks I was too lazy to post same to refute the nonsense. His profile shows he doesn't have a blower or even m3.

Will those SSP clutches hold 650ft-lbs

The Schwaben scanner does, in fact, perform the clutch adaption routine which teaches the TCU the thickness of both clutches. Checkout the pictures below of the scanner screens as I went through the process today. Unlike uploading a DCT tune, the car has to be running with the transmission temperature between 60 - 100 degrees Celsius, in neutral, and with the brake engaged. The car would rock/shake a bit as the DCT was engaging and measuring the clutches during the procedure.


















Personally, I run the clutch adaption routine every 15K - 20K miles so that the DCT can optimally use the current state of the clutches. Having driven a manual for 19 years, I would alter my use of the clutch pedal based on the current thickness of the clutch. Thinner DCT clutches without proper calibration naturally leads to more power being applied before the optimum contact and friction point during a gear shift or launch. It's like giving it too much gas before the clutch starts to engage which can lead to either advanced clutch wear or too much slip. This, of course, is only during gear changes. The fact that the DCT can vary the line pressures based on clutch thickness can help with holding power while in gear. Please look at the before and after clutch adaption pressures in the pictures. They went up after the adaption routine.


I am not stating that running the clutch adaption routine will fix your slipping clutches. I am stating that you can run the clutch adaption routine by yourself with the Schawaben scanner and not need an indie or dealer.

I have the schwaben and can back up your claim that it does the clutch bed point adjustment. However, if your DCT clutches are at the point they are slipping, they are already toast. This may bandaid the problem, but full clutch pack replacement will be required very soon.
