dkg software udate
sport auto says there will be a software update wich improves upshift speed and the change into backwards gear. nothing was mentioned about downshift or any lag problematic.
i test drove a dkg car last week and was not happy. i had the downshift issue on the autobahn while braking from 240 km/h to 180 km/h (far away from abs area) much more annoying and also dangerous was the fact, that if you go close to the rev limiter e.g. in 2nd or 3rd gear and then change into next higher gear first of all the acceleration stops, then you have a lag and all of a sudden the system hammers in the next gear...i do not want to have this in wet conditions i called bmw m to ask whether these problems will be solved with the next software update cause i ordered already a car with dkg...they recommended to wait one year... so i changed back to mt

If BMW is telling people to wait a year, maybe we should cancel the orders until next year! Was it an 08 or 09 you drove? |

If this original post is true, that's quite a bombshell. I don't want to doubt that BMW M is telling people in germany who call them, but I can't imagine corporate anything telling people not to buy the product now.

I am a very happy M-DCT owner, and sure there have been like 3 glitches in several months of driving. Nothing that ever put me in harms way. BMW will make things right.
Just enjoy the car, and enough with all the negativity |

This sounds pretty hard to believe. Who did you speak with at BMW? Or, for starters, what phone number did you dial?

First year cars always have glitches, best to wait until late second year, or third year. Yes 6MT would definitely be the way to go right now, IMO. 70K large is just too much money for these kind of issues, all though thats just the nature of things with this tech.
BMW will sort it out in time, hopefully not too much time. |

I'd be more worried about a physical (non-software) change in the DCT that is characterized as an "improvement" not a "repair" and, thus, won't be applied to the existing cars? Sort of like a SSG, SSGII, SSGIII progression. Maybe the 2010 car will just have DCT II and that will be the end of it.

Anyone else with DCT experience the OP's shifting anomolies? I'm not saying it didn't happen, I'm just thinking this was an oddball occurance under unique circumstances.

I have had some issues, but not those the OP speaks of. Edit: I should point out that I have had ignored downshift commands....but they were NOT under heavy braking or at high speeds! This happened while just "normally driving" the car.

I too have had the acceleration stop as I was trying to shift right at or just below 8400 rpms. I have noticed it only once as I rarely redline my car on the highway. To keep constant acceleration, you must shift around 7500rpms, as someone mentioned previously, to keep the engine from basically stalling out at 8400+ rpms. Despite this one time, I love the M-DCT and would still take it over manual anyday.

This stalling out, as the OP calls it, is almost certainly running up against the rev limiter and is operator error, not a transmission issue. Someone please correct me if I am wrong. I think we can write this thread off.

It never happened to me "yet" (not even once and I hope it will not) but I always use the shift light indicator to guide me when to shift. There were times that it will not shift gear but all of them were operator error (mine) not pressing the pedal brake before shifting from N to D/M.
