Brake, ABS, Tire Pressure, etc. Warning Lts

aweesner · 07-16-2010, 01:43 PM

On Sunday a whole host of warning lights suddenly lit up...

- ABS
- Tire Pressure
- Hand Brake
- Triangle with circular arrow in center

They have all been on since Saturday with the exception of one time on Wed night.

The car seems to be operating fine.

I'm not sure if this is relevant but we had super heavy rains here in Boston on Saturday and I drove through some 6-8" puddles.

Any ideas on what is going on?

One of your ABS wheel speed sensors has probably gone bad.

Not sure but don't drive it. If you had a battery light come up too, I'd say your alternator is real close to eating crap.

+1 on the speed sensor, also see my sig.

It might need a wheel bearing. IIRC, there is the wheel speed sensor which goes in to the knuckle that reads a magnet that is part of the wheel bearing. Is that correct?

This is a common issue on 2006 330i's. I have had it and have shared my story with several who have and it helped them resolve the issue. It is highly likely you have a bad rear wheel bearing and abs sensor. I had to take my car in two times to get my dealer to figure it out. They ended up sending data to BMW who told them what was wrong. The error codes they will see will not tell them it is a wheel bearing. In fact on my first visit they decided it was a bad battery. Of course they were wrong. The repair is about 800 bucks if you don't have a warranty. You can try just changing a wheel sensor but if that does not fix it then it is a wheel bearing.

wheel speed sensor. relatively cheap fix.

Hey Tom, how did they find out which corner the wheel bearing was faulty on? Did they have to read the speed sensors?
