I've read this thread and not sure what to do, I can't get away from the DCT clutch judder/shaking when in manual s1 mode (I have an M3 F80). My setup is: s+ throttle, s suspension and s steering and lowest gear change setting.
In manual mode the clutch judders (car shakes) in first gear when I am gaining speed (between 1k to 4k RPM). I have to change to second gear for the judder/shaking to stop. This happens a lot, even when I try to be as smooth as possible on the accelerator (it's very senstive). The judder doesn't occur when in second gear (if it does, it's very infrequent) and there is no judder at all in other gears (I'm in sport plus in throttle, s steering and s suspension). I also notice that the shaking/judder happens when I suddenly go over a bump in 1st/2nd gear too. I find it hard to believe that these symptoms are normal. Anyone experience these issues specifically? I may have to get the dealership to look into it (still under warranty and low miles - 12k). |

There is nothing wrong with the car. I am not sure why people think 1st gear is a gear you can stay in for anything but a few seconds. 1st gear is just to get the car moving, that's all. You are giving it too much throttle in the wrong gear in an aggressive Sport mode. Shift to second quickly.
Also watch the cluster when it downshifts too. You will notice it goes into first literally right before you stop. That mode is too aggressive to be in 1st gear for more than a second or too, simple as that. |

I love how the car sounds in sport plus, annoying it cannot be used (I'm no newbie to performance cars btw). I've read some people find it very sensitive and some don't at all, which makes me think it could be due to a firmware update or something. BMW ought to have done a better job when setting these functions up. Also, I've learnt that it's not DCT judder/slippage, it's loss of tyre traction. The DCT itself doesn't cause it. |

These judder symptoms sounds like my E46 SMG. I get no judder when engaging 1st gear with my DCT. I do get the bucking when I am flooring it and then let off the gas quickly at a high rpm.

I'm thinking this has to be some sort of computer fault/setting when it reads how much pressure you put on the peddle when throttle is in sport plus. Will get it checked out at the dealer some point this year. For now, Sport mode it is... |

Hm i see, well the only way i don't get judder (when in sport +) in 1st is when i very lightly (like a snail almost) build up the rpm in first. Then once I'm past around 3-4k revs, I can keep flooring the sucker without it jerking.

FWIW, although this happened to me a couple of times after the break in service when I started to really get on it out of the hole, I drive around in S+ throttle and S3 DCT all the time (I just want full beans available) and I have not had the bucking issue ar all since I sorted out how to launch it. Now, about 5500 miles on the ODO, I tend to run the DCT in S2 (throttle is in S+ 100% of the time for me), but it is definitely possible to avoid the bucking in S+/S3 with proper technique, even on a moderately spirited pull off the line.
Lots of good advice here, but some have suggested that you have to go full tilt or super timid in S+/S3 to avoid bucking. In my experience, this is just not true. There is definitely a learning curve with this car, but it is very satisfying to get yourself dialed in. I’m not saying that some have not experienced software issues that may exacerbate the natural tendency of a high powered car with a very short first gear to buck, but ultimately this tendency can be managed by the pilot with some experience.

What ISTA version does your car have, I had similar problems but after getting last year’s latest software version, the problems went away.

OP stop being so indecisive. Either get on the throttle or get off it. Stop being such a bitch.

Lol. Seriously though OP, if it is an ongoing problem, take it to a dealer or a speed shop and do a test drive with them. See if it happens when someone else drives it.

It's a throttle sensitivity issue related to suspension setup when setting off in 1st gear from rest, rather than a gearbox issue. Combined with any sort of road surface bump, together they set up a rapid vicious cycle that can result in the car Kangaroo hopping down the road. It can be driven around by backing off the accelerator pedal completely, flooring the accelerator (usually not an option on a busy city street), or manually changing into 2nd gear. An analogy of this problem is the occasional car where the driver's seat spring rate has clearly not been set up in harmony with the vehicle's spring rates. Same-same but different. If we found this problem in a Korean or Chinese car we'd be poking fun at their primitiveness. But it's certainly an eye opener to find it in a top-tier German car builder. So yes, the issue can be driven around, but it should never exist in the first place in a well designed and well sorted car. |

Never had any issues accelerating in 2018 F80 Competition in Sport+ smooth uninterrupted power endless. My car buckles sometimes in 5 o clock rush hour traffic though.

Bucking Sport+?
Hey I just picked up a DCT F83 M4. Just wanted to know if anyone else experiences jerkiness or bucking when in Sport+ in first gear. It felt like I was learning how to drive for the first time lmao

just gotta be careful with the throttle. touchy throttle + firm suspension on a bumpy road is gonna make your foot bounce a little. also why a lot of reviewers prefer just leaving the throttle in comfort even for track days.

Yes.. I thought it was a misfire or something was wrong with my car. Hahahaha I'm so glad I'm not the only one. First DCT car and I got it on Friday. So still a bit in shock, but I guess it's normal since you have the same feeling.

A car with twin turbos in a more aggressively mapped throttle setting will do that. I'm not really sure what you expected, there's about 100 other threads you could've honestly looked through that extensively talk about this. It's an automatic transmission that acts like a manual transmission, it's not going to be the smoothest experience in sport plus if you don't have good foot control.
