Backfire gone?
Hi everyone
Took the car in a few days ago for a new windshield, oil change and they did a recall. I am assuming there did a software update. Was fine for a couple days ..
Today the car is not backfiring or popping on downshifts. Its also not downshifting or holding gears properly even in S3. 2020 M5C.
Called the dealer and he is talking to the shop foreman.
Any thoughts?
