Hi guys,
I have an M340i xDrive. I recently had my car side swiped while it was parked. They hit the driver side front to back. I got my car back from the body shop and cosmetically the car looks perfect. Also, while the car was in the shop I had my rear tires replaced. I have the Pirelli Cinturato All Season RFT 19's not staggered.
Now when I'm driving at certain times I noticed especially when i'm driving uphill like when i'm driving on the uphill part of a bridge the traction intervention kicks in many times and cuts power to the wheels. The car doesnt actually feel like it's slipping though. I'm talking about completely dry outside 70 degree weather. I thought maybe because the tires were new but I have already put on 700 miles on the new ones and its still happening. Does anyone here have any insight to what this could be?

Did they replace all 4 tires? Were they replaced with the same type and spec.?

Sorry now I see it was rear. It could be if the fronts are worn after X,XXX miles they're a different diameter due to tread wear and are spinning at a different rate than the new rears. The car sees this disparity and thinks there's a traction/stability issue.

I replaced the front 2 months ago and they have 2,000 miles on them so they're fairly new.

I'd bring it to a dealer to see if there are any underlying issues caused by the accident.

Yeah that's not enough to make a difference. There's something else going on.

Could one, or more, of the wheel speed sensors have been damaged by the accident? Or even during the repair and tyre replacement? If so, it might be giving a false reading, or no reading for one wheel, causing the traction intervention to kick in.

Could be. I brought my car into service. I'll see what they say.
