I just finished reading this entire thread and would now add my own frustrations with the DCT.
Bought my 2011 135i with DCT, (sport, prem pkg) on Aug 1st 2011 at 25 miles. Drove it home (35 miles) and then the fun began: Put the car into reverse to back up into my garage, and while my foot was still on the brake as soon as the shifter returned to middle the car started to violently jerk backwards as if the dct is trying to drop the clutch. After 3 jerks within about 1.5 seconds the engine stalls (which is usually the behavior of dropping the clutch in a manual while holding the brakes, except this is an automatic. LOL). Of course the dash lit up like a cristmas tree with all sorts of warnings. Foot still on brake, push the start button, car turns on and within half a second wham again starts to violently jerk backwards and again stalls itself (this time I didn't even touch the shifter). I am assuming the second time the tranny was still somehow left in reverse gear since the car stalled the first time. 3rd time, as I turn the car on I was frantically pressing the P to try and get the tranny out of whatever mode it was stuck in and thankfully that worked so then I put it in neutral and rolled the car back into my garage. Next morning, off to the dealership, D works, pull forward out of garage, figured what the heck lets try R again, works like a charm this time around. Went to the dealer, described the problem, they refused to give me a loaner because I hadn't scheduled an appointment and said they need the car the whole day to diagnose. Well sorry but I kinda have to get to work so I drove off. No problems for the rest of the day. 3rd day, car is fine in the morning, but in the afternoon it decides to act up again. This time I was filling up gas (the dealership that sold me the car kinda forgot to put gas in it...) and as I got back into the car, turned it on, tranny will not shift into anything, D, M, R, N, just sits there in P. Tried turning the car on off about 4 times and trying to get the tranny to do anything without any luck. Foot off the brake, moving the shifter gave the audible warning that you need to press on the brake so I know the shifter is working fine, but the DCT would just not shift with or without your foot on the brake. So I just turned on the flashers and started apologizing to the line of cars behind me waiting for their turn to gas up. Went in the car about 15 minutes later, turned it on, and viola, everything works fine again. Drove straight into another dealership, and they took the car in. I didn't even bother with requesting a rental, just told them to get the damn dct fixed - I arranged for alternate transportation myself. Now at this point in time I should mention (eventhough this is a DCT specific thread) that also prior to getting gas on day 3 I had seen a low-battery warning as well as a random service needed warning, but I figured hey the gas station is on the way and I might not even make it to the dealership cuz I am driving practically on empty). Anyways the battery and service needed were completely separete issues repaired at later service so I am going to ignore describing those and focus just on the DCT. So rather than describing the service done, I figure its best to just post it here: Postings of the 1st and 3rd services of the car, as I didn't get any paperwork on service 2 O__o So the overall outcome is that service 1 seemed to correct the DCT issues through software reprogramming, but totally botched the service on the battery and the 'service needed' warning, the second service supposedly they just reset all service intervals (thus no paperwork) which 'fixed it' for only 1 day, and the last service replaced the battery and seems to have done some CBS reprogramming. After the reprogramming, the DCT hasn't had the stalling problem or inability to shift out of park, but has been extremely sluggish in response, just as many others have expressed in this thread. Mashing the gas pedal would sometimes take 1 to 1.5 seconds before the car responds... This kind of hesitation is just downright dangerous. It happens from a dead stop (about a 1s delay from mashing the gas pedal and the car actually starting to move) and if coasting in 4-7 or only slowly accelerating in 2-4 mashing the gas pedal results in 1.5s delay before the downshift occurs and the car starts moving as expected. Driving in sport D, or S, or Sport S doesn't help at all in response in the above conditions. Only in M at least you get instant response *in the currently selected gear*, but manually downshifting while pressing the accelerator results in about .75s of delay when the power delivery just stops right before it hooks up the gear and glues you to the seat. Oh and somewhat irrelevant to a DCT thread, but recently (about 800 miles on the car) started getting an annoying rattle in the roof rear area as well as longer cranks. One thing after the next... Almost no full week has gone by without a need for a visit to the dealership. Car isn't even past the 1200mi break in period yet, but it sure is borken !!!! |

Why is the dealer blacked out? What dealer jerked you off?
Taking off from a stop should be instantaneous, for that reason alone you should take it back to the dealer for service. Report stated your DCT over heated without reporting it to you, this deserves a new DCT. If it were me, I would ask for a new car. |

Well I figured I would give the dealer a chance to make up for all the trouble I have had with this car, but even with my complaints and a call to BMWNA not much seems to be happening so pretty soon I am just going to open a new thread in the maintenance section and post all my eletronic correspondance with service advisors/managers, customer relations, BMWNA, and service descriptions without any censoring of the dealerships and people involved - prb won't do me any good, but it would at least help others that are considering purchasing cars from the same place I did.
The fight with dealers/BMWNA is basically coming down to the fact that the dealerhsip that sold me the car has had it on their lot for about 10 months and in that time they didn't bother to do *any* inspection of the car and just ended up selling it to me. Because of the long period of time the car was just sitting there, its battery (never being recharged) was basically on its last breaths and needed replacement, 2 recalls were missed as the SIBs were distributed after that dealership got the car from the factory, and not to mention that the fluids like oil/brake were halfway through their 'calendar' life, eventhough the car has no miles on it. They were prb happy to get rid of the car off the lot and I got stuck with a 135i that passed the 3 mile test drive and started showing its first problems another 10 or so miles after all the paperwork was signed Unfortunately in CA a "new car" is defined as one that hasn't been titled before, so technically a dealership can sell you a car thats 1 year old after it rolled off the factory floor as brand new. |

Not entirely contributing to this thread other than to agree on the above. Car went in on Friday for slight rattle to sunroof and creaking rear suspension (which went away on its own) and I noticed worse fuel consumption figures than even I've managed when running the car very hard on psycho runs. Most effin pissed off and will call the dealer principal tomorrow to give them some shit. They should respect owners' cars and fuel - all ends up costing me money.

I didn't have as much of a lag problem until the first software update. Before then, you could still get a good launch out of it even in normal drive. When you rolled on the throttle hard, you would hear the engine bog just a little like you would with a normal manual and it would build quickly from there. After, the update, it was just soft, nearly unpredictable, and didn't have the crispness it did before. It wasn't even as good a launch as I got out of the 328i loaners with a real slushbox. The consistency was just not there any more. What was even more annoying was rolling on the throttle, nothing happenning, so you roll on it more and more until something did. All of a sudden, you were off an running and getting a lot more than you really wanted.

Update 9/9/11
Good and bad news today
-The Bad- I had a car inbound on the boat and BMW decided the trade assist didn't work for that one. I'd already tried to locate another 135i with 6sp and Sport/M-Sport and there was nothing out there at the time. My salesman started looking for a 3er coupe or sedan and found me a silver on black 335i performance edition sedan/nav/premium/hk/6sp/sport pack. Thought that was the end of the search until today when I got the call that the deal didn't work the same unless I was going into another 135i. -The Good- I said fine, lets try to find one. He'd already found an AW on black/premium/hk/comfort access/6sp/MSport. I said that sounds pretty good, but it'd be better if it had heated seats or coral red. Within 10 minutes, he'd found the car just coming out of production. AW over coral red butt warmers/hk/nav/6spd/MSport. I've got the build sheet in hand with my name on it! Someone must've been watching me configure a car on the BMW USA website one day since I built the same car. I can't wait to be a 1 owner again! |

Was having similar issues a few months ago but for me it was just when slowing to low speed it would like stall and go into neutral. When I turned the car back on and into drive it would just go. No issues with crunching noises and lost gears like you. But after one of the time I took it to the dealership for one of the recalls with the computer I have not had the issue again.
Hope your issue get resolved.

[QUOTE=gmartan;10363020]I've hated the lag since the day I got it, that and the RFTs. Tires are changed out but can't seem to find a way to fix the lag. It is annoying froM a dead stop but it is twice as annoying when you have taken your foot off the gas going into a corner and hope to power out of it. By the time it comes on the corner, and the fun, is long gone. Feeling your pain!
I am having exactly the same issues with my DCT. It goes in tomorrow as I now have noise in the transmission when it engages. Of coarse, not every time. I am seriously considering taking the car across the street and trading it in if they tell me nothing is wrong with the car. I have had BMW, Mercedes and several Porsche so I am experianced driving sports cars. My father raised a car girl and I know when something is wrong with my car. I also have lost all power when accelerating to avoid a problem on the road. VERY dangerous! |

I also lost power while trying to avoid a problem... that is definitely an issue to look out for. Now I make sure I'm in the optimal gear at all times. I always drive in manual mode to be sure I can select the gear. Now avoidances are not a problem and around turns I get all the power I need. The DCT is a great transmission, it just has it's quirks that you have to learn and also learn how to use it correctly. Software problems are an issue on some cars, but sometimes I also wonder if this is partially user error.

I drive it in manual mode all the time, because it's fun and I like to be able to control what gear I'm in. I must have gotten one of the good ones
Just curious, what are the build dates for some of you that are having problems? Mine was built 5/10.

The car is in the shop and I haven't checked yet, but I took delivery of my 2011 in June of 2010, so it is an early build for 2011

If you never drive in full auto mode, you're not going to see the lag problem that many of us are describing. You could still have a 'bad' one and just not know it. |

Just curious, do you all have the new DME update? I didn't get it yet. Take it in for an oil change on Monday.

I no longer know since I don't have the car anymore. I purchased it in Dec '10, so I think it was a Sep '10 production. I got the new DME update in May '11 when it first starting having lag problems around 5500-6000 miles. Notice that it wasn't until then that it became pronounced. I was never excessively hard on the car and had used launch control once to just for the heck of it.
I agree there's got to be a little lag for clutch engagement, but taking up to several seconds is a little ridiculous. Especially when it wasn't evident in any mode I drove the car in prior to accumulating several thousand miles. The car was consistent in how it pulled off the line whether in manual, auto, or sport and whether I rolled on the throttle slowly or aggressively. It just got downright dangerous puling out of my neighborhood and made me rethink what I was doing anytime there was a car within 300 yards or so. This doesn't even go into the other weird things that happened such as the "unwanted" launch control without being setup for it, shifting into park while the vehicle was moving, etc. |

Here is the update on my 2011 135i Sport DCT. Two weeks ago I picked the car up from service. Again was told there was nothing wrong with my car. As I pulled out of the drive I paused. Go right, head home. Go left trade the car in. I turned left and traded the car in. Yes I took a hit as I traded rather than sold myself which I usually do, but I can't sell something I don't believe in. I bought a 2011 (2012 wasn't out yet) 335i Sport, auto with paddle shifters. Never thought I would have a four door sedan, but I have been surprised how much I like it. The car is great. Lot's of power, but none of the DCT issues. I love a manual, but not for a daily driver in Houston traffic.
