2015 435i Every warning light on

stevesbmw4 · 09-17-2022, 12:43 PM

All of a sudden, virtually every warning light on the dashboard has come on:

Chassis stabilization
Airbag
Seat restraint
Check engine
Cruise control malfunction
ABS
DTC
Steering

What is going on here? This many things could not have all gone wrong simultaneously. The car drives normally. I just had the alternator replaced, and the battery was tested and is fine. Any help would be most appreciated.

There’s no way to tell without reading the codes.

Examining all stored codes is literally step one. Keep us updated.

Mine did that when an ABS sensor had a glitch. Anything and everything that relies on the car knowing how fast it's going won't work without all four ABS sensors functioning. I diagnosed and cleared it with my Foxwell NT510. It didn't happen again.

How old is the battery?
