FUBAR 4.2

Hey Guys,

Any tips or tricks to get rid of the "Air Bag" light on the dash?

I start the car, it goes off, and then about 10 seconds, the "Air Bag" light comes on and stays on...

This started right after I got an oil change done - could my mechanic have bumped or loosened a wire or connection?

Thanks,

KevinGary

I am betting the sensor in the back seat has gone bad. It is a known problem in our cars. I have had mine replaced 4 or 5 times.

Interesting...I just had my center rear seatbelt unit replaced for the same reason (tech said it was faulty seatbelt pretensioner). I got the car back and a little over a week later, the light's back on...taking it back to dealer tomorrow for that and other reasons:

KevinGary - From your TSB link, I'm guessing this might apply:

It's from the rear center seat belt. They replaced mine too and it keeps coming back on whenever someone sits in the back middle, which isn't very often. I just reset it with one of these... http://www.dealextreme.com/p/u600-2-...r-1-6f22-35186

Sometimes a simple clearing of the code will remedy the issue. I had my airbag light on and the code was for a faulty sensor... My mechanic cleared the code and it hasn't been back since. The sensor must have had a momentary glitch.

Thanks...I mentioned this to the dealer who's keeping it another day to trouble shoot this and and an oil consumption issue. My 8 year old has recently taken to sitting in the rear middle seat when his big sister's not in back with him...definitely could be a faulty sensor of some sort since the dealer just replaced the seat belt assembly/pretensioner 2 weeks ago after I got the first airbag warning light.

In the meantime I'm enjoying a loaner Q5...

I've had the air bag light showing up for a few years. Only on real cold days originally. The VAG showed it was the driver's airbag but was "intermittent" and I would clear and it would go away. A few months ago it popped up permanently and would not stay off. I figured since it was originally intermittent it might just be a bad contact. Today I took the covers off the column and re-seated all the connections I could find. Another VAG and cleared the old codes and the light is gone. I figured I'd post this as I've read postings about the intermittent code but never a post of the fix.

Dealer ended up calling Audi technical support after I mentioned a few of the comments I'd read here previously about others having the same issue with the center rear seat triggering the air bag light - apparently issue was not the seatbelt/pretensioner system that they replaced. I spoke to the SA briefly on Fri. and they said they were ordering another part (a connector of some sort I believe)...hopefully will have it back on Mon and will post more details then.

"It's from the rear center seat belt. They replaced mine too and it keeps coming back on whenever someone sits in the back middle, which isn't very often. "

Exact same scenario with my car. I've just learned to ignore it over the last 4 months.

Got my car back today. This time around, after consulting with Audi tech support, they replaced the wiring harness (4F1-971-259) and grommet (4BO-886-373-01C) and believe they have it fixed. My 8 yr old sat in the rear center seat on the drive home tonite...so far so good (no air bag light)...keeping my fingers crossed!
