The dash warning mystery... 330i

qapla97 · 02-12-2011, 10:09 AM

I have a 2006 E90 330i 4 door w/sports pkg/prem pkg and 40k miles - I'm running Blizzaks Runflats in slippery weather with OEM wheels

Today, when starting my car... the Traction Control, Low Tire Pressure and Brake lights came on (all green in color)

I stopped and restarted the car. The previous warnings were gone, but then the airbag sensor came on and stayed on (red in color.) Even after restarts, the airbag light is on.

The mystery is this: WHY did those other lights come on ... it was not coincidence. BTW, my ABS, DCT and Air pressure are all fine.

(I have not read faults or taken the car in yet. Airbag light still on.)

Thanks all...!

Pull the codes

A failing battery can cause false warnings like that. Is yours original?

A failing battery should not trip the ABS or DTC lights. They are safety systems and should never be able to be disabled (well DTC can be disabled but ABS should not), especially with a weak battery.

OP, you need to pull codes.

It is original... what an interesting theory. I noticed on one of our really cold days I had a slow crank. But it's been pretty solid since. I've got an appt Fri locally. Thanks all.
