Sluggish pull in 1st gear
Hey everyone,
The other day I was at a traffic light and when it turned green I pulled off in first gear, but when I did it stuttered/coughed 3 times jerking the car a bit (back and forth) before driving away normal. Any ideas why this happened? I like to think my clutch control is fairly decent after almost 10 years of driving. This has happened 2 or 3 times. Also when driving around in 1st/2nd gear around town, mainly London so speed is normally under 20mph, the car just doesn't sound natural and has metal like sounds. Am I overthinking this or is this normal? FYI car is at 3700 miles and used to motorway driving.

I still have to practice with it more to figure out why this happens, but that's my only thought on it so far. Curious to see what others have to say.

the sluggishness in 1st and 2nd sometimes is the torque being managed when DSC is fully on, set it to MDM or DSC off and you will not experience this. note that it is not wheel slip - DSC is actually predicting that the wheels will slip and proactively reducing the available torque before they do. kinda annoying but also kinda smart.

I’ve noticed the exact same thing. I almost thought it was the car throwing me back and me lifting as a result but like in an on / off jitter kind of a scenario.
However I haven’t noticed it in a while and I have recently been driving with MDM on which I guess based on what’s been suggested above might be why. Let me know if you get the same effect. I’m going to try a few pulls with full traction on and see if I get a difference. It’s quite annoying if it is this. I’ve never had anything similar in my 140i... |

That's what I was thinking as well. I'll have to try in MDM or with DSC off once I'm out of the break-in period.

I get this with my M2 DCT and I initially thought the same thing. I think the car just doesn't like going slow in first gear, like most track cars. I live in a city and it happens when I'm stuck behind someone doing 15mph. And it especially happens after I'm on the treadmill at the gym, cause my foot doesn't have as much control after a workout. I just get up to 3k rpm as fast as I can and put it into 2nd.

...DCT posts are starting to mix in with the MT posts here lol...
The old SMG (e46 M3) was notorious for bucking like a bronco occasionally when starting in 1st gear -this happens when one's foot is not applying throttle in a smooooth manner; the quick fix a BMW instructor told me way back in the day was to shift into 2nd immediately. The DCT is sooo much smoother than the SMG, I'm surprised people still have this problem. The old SMG in automatic mode jerked every single time it shifted and was unusable; the DCT in automatic mode is good enough that you could have your Mom drive it, and she would never know it wasn't a "true" automatic. |
