lumpy bumpy kickdown

L3NNY · 12-17-2023, 12:26 PM

Has anyone else felt like the acceleration was a bit bumpy before??

Just got a new f31 with an N47t and when I put my foot down it feels quite bumpy, at thought I thought it was gear changes but it doesn’t seem to be, it kinda feels like going over cats eyes….

It’s stood for about a year maybe it just needs a run in but I have done about 400 miles and I still feel it

….thoughts!?

Mileage ?

Do you have the means to read the adaptations data from the transmission ?

Also the fault codes from the ECUs around the car.

125k miles

No fault codes that would really effect that have shown up on carly
