Active Blind Spot Detection and Lane Departure Warning Malfunction?

E92TiAg335i · 05-19-2022, 10:31 AM

Hey guys. Car has been running great. It's a FBO BM3 car. Yesterday, i went to get my midpipe readjusted as it was pushing up on my diffuser ever so slightly.

On the way home, i hopped on the highway and swerved out of the way of someone who stopped on the highway. My car immediately threw the Active Blind Spot Detection and Lane Departure Warning systems off and said "malfunction."

I got home and let the car sit (south florida - maybe it was hot?).

Today, i turned the car on and both systems activated beautifully. I took the car on a drive and swerved out of the way of a rock… boom. Malfunction comes back on.

Does anyone know what's going on?

How do all of your parking sensors look? Any of them damaged or knocked loose? Maybe something got knocked around a bit when the exhaust was adjusted.

Did you pull any codes yet?

Did not pull codes yet. Will do that after work.

I can tell you that backing the car in - the parking sensors work just fine. Haven't tried pulling it forward yet.

The radar is also mounted on the LH inside of the rear bumper. Probably want to take a look at that as well.

Update - tried to pull codes from BM3. Nothing showed up. Guessing i need ISTA to pull these codes.

Assuming it's a fried module…

Hmm. As much as I hate Carly, it does a good job to pull codes. Also ProTools.

What about bimmercode?

I don't think it has a scan function. At least I haven't checked or used it for that.
