Rear diff fault and many more

f82Haze · 10-04-2025, 04:50 AM

Hi all, today I was taking my f82 out and suddenly all of these error codes popped up (in picture). I have no idea what would’ve caused it, the car has 29k miles and is meticulously taken care of. Please let me know!

Here is the list of codes as well:

Chassis stabilization: Drive moderately
Collision Warning System inactive
Collision Warning System malfunction
Rear axle differential lock
Pedestrian Warning malfunction
Pedestrian Warning reduced

The car only has a valvetronic exhaust on it. Everything else is stock besides crank hub upgrade and aluminum charge pipes. Thanks!

I had that list of errors when my wheel speed sensor went bad. This is just speculation though, you have to scan for the exact error codes to find out the issue.

FYI my speed sensors went out at 20k miles so mileage has no effect on how long they last. When they go they go.
