I've had the car updated to the latest DME sometime last year but it didn't really go away. Car seemed to shift a little better but the issue was still there.
I just found these threads and saw that Bimmergeek's Protool can reset adaptations. I finally downloaded the tool, hooked up my K+DCAN cable with a OTG USB-C dongle and connected. Bought their diagnostic license and reset every adaptation I could find.
Under Drivetrain
Engine -> Functions -> Clear Adaptations
Transmission -> Functions -> Clear adaptations (there were 6, i cleared them all).
NO MORE SURGING WHEN COMING TO STOP! View post on imgur.com
Also the shifts seems smoother in nonsport mode and faster in sports, that could be the buttdyno speaking
I'm elated now, thank you BimmerGeeks ! |
I have the same tool, but I don't believe the RESET ADAPTATIONS are the same as using the INPA software. When I reset mine initially about a year or two ago, it fixed everything DCT-related about 98%. It now acts like it's coming back. I only get hesitation when using the A/C. When I reset adaptations with the BimmerGeeks software, it just says reset. When I would reset it through INPA, the entire car and gauges would "reboot" and I would get an error light the first time the car was started after that. It would go off after the initial start up.
I don't think the BimmerGeeks tools is resetting all the adaptations...

PS. I'll try to reset again tonight to make sure I didn't miss a setting. I'll check back in.
