4 service lights/malfunction at once?

VGSON · 11-07-2023, 05:25 AM

hopped in the car and got
Pedestrian /crash malfunction
Cruise control malfunction
Chassis stability malfunction
Brakes malfunction

Drives fine except no sport mode or cruise control available. no codes shown on my mhd suite. Only correlation was cold weather and tire pressure dropped to 27/28psi….

Anyone else run into this?

Bad battery?

I ran into this when swapping to CCB's. Doing a search found that it's a sensor issue that can be be caused by several things. Mine was caused by the brake light switch. Yours could be the battery, or something in front of the camera on the windshield, or even something else.

Do a google search for "Bimmerpost Pedestrian Crash Malfunction" and you'll see several threads/responses with several causes.

Codes didn’t pop this morning and cleaned really well in front of camera. Hope thats it..

follow up. turned out my brake fluid was low.

stopped by autozone to read codes since mhd showed none.
only code popped up was brake fluid low. Shop wanted 150 to diagnose.
Bought a bottle of fluid and topped her off. Figure with all the dash lights and sensors bmw could have had the car just say its brake fluid is low vs all this bs.
