Solved: Traction control issue preventing acceleration at high speed
I haven't seen this covered in many threads but the issue is real.
Symptoms: TCS gets confused when going WOT at high speed (60+ MPH, 6th gear), thinks the rear wheels are slipping and starts cutting power. This seems to affect older cars (mine is built 03/2017) and the problem gets worse with square tire setup (245/45/18 in my case). Solution: update the DSC software (I went from 505 to 530). The updated software has much less intrusive stability control. Besides solving the above problem the car is way more fun to drive when DSC and TCS doesn't panic all the time. |

I'm not sure what version my software is on but I did end up coding the euro dsc settings as well as M4 gts mdm and have no complaints or traction issues. My car was manufactured 10/16.

The only other search hit I got was for someone with overinflated tires describing similar symptoms. When you go to the dealer I suggest not bothering with explaining the DSC troubles, just complain about the iDrive locking up and going blank intermittently. They will update the whole car. And if you are running older software you will notice a big difference in DSC plus slightly better steering feel, and with manual less boost loss when shifting. |
