Chasis stabilization warning question
So while I was driving to work the other I get 3-4 error code on my 2018 m240i which has about 72k miles
Brake system error: stop carefully chasis stabilization error daytime pedestrian warning reduced and frontal collision warning system error Car still drives fine, and later on that day, the error went away. That was last week, this morning, it came back again. (Both error happened early in the morning when its cold out) I didn't drive it hard, but on regular driving, brake and driving feels fine Anyone experienced this or know what to look at? |

I don't know where the bumper sensor wires run but all of those errors could be coming from a single corner. The sensor errors show front so if you want to go digging, pull a wheel off and peel the fender liner looking for damaged wires. The acceleration sensor and EDC wires go into the same junction box, I think ABS sensor goes to a similar area. Hopefully not rodent related...
The other option is clear the codes and ignore it until it comes back again. I did replace a corner's acceleration sensor once, but it only caused a chassis stabilization error (and related code). I don't have experience with the other errors. Last edited by freakystyly; 04-09-2024 at 02:58 PM.. |

Update:
After noticing the increasing frequency. and the fact that it started with error only in the morning when its cold. End up checking the first thing I should have check, brake fluid. It was low around near or below min line. Top it off and error went away. Next I just have to hunt and check for leak. |

I've got a German washing machine I have to pull the book out every time I use it because I don't use it often enough to have memorized everything that's in it. It and its cousin, the dryer, shouldn't be allowed to be sold outside Germany. Or Austria and Switzerland, too. Maybe.
