Angry Airbag sensor failed AGAIN!

Well...as it has every two years for the life of my car, my air bag light has come on again for the third time.

The first time was a wiring harness and the second time it was the sensor mat in the passenger seat cushion. I just got a call from the dealer and once again...it's the freakin' sensor mat in the passenger seat

Has anyone else had reocurring problems with the airbag systems in their E46's? Over the years I have been hear I don't recall anyone else griping about it like I have. The SA was very surprised to hear that this was my second sensor mat. In fact he could only remember one or two EVER failing in ANY car before, let alone TWICE in the same car.

Call me lucky I guess.

Good part about it is I got an X5 3.0 for a loaner. I don't like driving it, but it isn't a bad trade for a 6 year old E46 with 110K on the clock.

Maybe if you didn't drive so agressively that your passengers soiled the seat, you wouldn't have this problem?

sensor mat? as in the one that detects if you have a passenger or not so it can accordingly deploy the front passenger airbag? I would think that's an optional fix ....they could just set it to deploy all the time....

both front seats have one of those each installed.
And yes, they do fail.

It also contols the speed at which the air bag deploys so it doesn't blast a small passenger into the back seat.

Are you still over at Scott AFB? I'm guessing you got the X5 3.0 six speed. That's the one I've asked for since it's the only manual loaner.

I agree with you, though, sort of a weird drive.

Yes, I'm still at Scott.

The car I had was a silver X5 3.0 with the Step. I didn't know they had a loaner with a manual...hmmm...I'll have to remeber that when the parts come in.

Yup, X5 is the only one with the manual. In fact, the woman who gives you the keys to the car is always happy when I specifically request the manual. She says that nobody ever wants it.

BMW should get more involved!!!

You're not the only one griping, I hear alot about the seat belt tensioner and wiring harness among other problems dealing with the air bag system. I guess BMW has not worked out all the bugs out of their safety air bag system. The more complicated and computer controlled machines get, the more bugs require patching and/or repairing. If it's not the air bag light coming on, it's the engine light because you haven't fully secured the gas cap.....I would advise investing in an air bag and engine reset tool/code reader. I got one from Peake and it helps alot with diagnosing the problem.....although BMW should get more actively involved in these reacurring problems since it is not just isolated incidences.
