DCT slipping **Does not have update software**

Hi All,

I've been driving my car at D2 with Power mode off. I'm not being aggressive but coming off a red light, I feel the gear slipping initially first. Is anyone experiencing this as well? I have a 2011.75 e90.

D2 is supposed to allow some degree of clutch slip to accomplish the softer shifts in that mode. Try driving is d4 or 5 and see if it still does.

Once you give the throttle a tap, the clutch should engage without any slip in my experience regardless whether you're in D2. Now if its a uphill during start, yes it does allow some slip (which I guess you want to avoid as much as possible to minimize wear).

Cheers

DCT has wet clutches, so it will feel like it is slipping sometimes - especially if you are accustomed to a manual gearbox.

Hi Mike, asked somebody else but not received answer, maybe you can help mate: Do you know what the specific difference between GTS tune and OEM Euro is?

Thanks

Get out of D2.....it was designed for use in lower traction situations and in fact can cause a lot more wear on the clutches as in fact they are being "feathered" in like if you were slowly letting the clutch out on a manual.

I believe thats correct ie harder setting = less slip. On the other hand D2 while warming up doesn't add much power the clutches anyway so I wouldn't worry.
I personally typically swop between D2/D3 while warming up if I don't go manual (S4) straight away.

Cheers

Ps. I never use D1 other than for playing with Winter function as starting in 2nd gear. Btw Euro DCT start default in D2 so natural start "sequence".

So the NA DCT starts off in S mode. Wonder why.
Anything to do with "slippage" and warranty when constantly using D1/D2 in our lawsuit happy country?

D1 force the box to start in second. Believe it might need a certain temperature (low) to work as well. Not sure, don't use it often.

Not sure. Apparently the US and Euro have diffferent tune were US boxes seem to have more lag. Strange.

are you referring to the euro mdm tune? or is there a separate dct tune aside from the gts tune.

Ref to the DCT, having different sw. For example US default S3 (?) while Euro in D2 but also US seem "slower", which why Im asking Mike and the experts about the diff between Euro and the GTS version flashed in the US.

Curious,
Cheers

Listen, either way the thing is not going to blow up early cause you used ANY of the D modes during warm-up, as warmup is such a small amount of mileage and time on the life of most S65s. The only thing you have to worry about during warm-up is rpm level and ferocity of the acceleration.

DON'T WORRY, that trans is a tough bitch
