2000 A4 Airbag Light

The unit is under the left backseat on mine (other model). I had problems like that when the seat was put in without taking care of the wiring.

Yep, I had to have the seatbelt until (which apparently has the sensor in it) replaced under warranty a while back. On my car, it was the passenger's side rear (LHD).

So are you saying the light should come on when a rear passenger buckles there seatbelt?

No, it should NOT come on. It WAS coming on and staying on (sometimes blinking) prior to having the seatbelt unit replaced.

Got it, thanks.

Do you happen to know if while that light's on, an airbag won't deploy?

The whole control unit should be deactivated, as the system report some failure. Too bad, if one airbag blew out by mistake ;-)

Well, that's a good question, the owner's manual doesn't specifically say what would or would not happen with the light on. I'm not sure if the side curtain airbags are one big unit that covers both front and rear windows, or are 2 separate units, one for the front window and one for the rear.

That unit controls them all (also front ones)!

I guess it's just best to fix the problem rather then finding out the hard way.

Thanks
