My 03 A6 Avant's driver rear sensor has been coming on and off while driven.. Of course this is a pain at night since the lights trigger. I happen to adjust my lumbar in the seat all the way down and BINGO, problem gone. I adjust it back up and the problem re-appears. Seems to be a short in the seat that is agitated when getting pressure from the lumbar... Anyone every experienced or heard of this one?

never heard of that. When you say lumbar you mean the cushion that comes in and out to support your lower back, or when you put the rear of your seat up and down?

 

Yes actually, it more common for an airbag light but i believe its covered under one of Audi's TSB's.

 

Disconnect your drivers rear door footwell light. It is the light that is under the butt of the driver and lights up the floor for the rear drivers side passenger. Your problem will go away. Well it should.

Look for the harness under the front of your drivers seat and disconnect the black plug. See pic. It's the top black plug in the picture.

Your problem should be solved, and the only downside is that butt light doesn't work anymore. I'm sure you could find the short, but I could care less about that light.

 

Jelfa - Are you telling this guy to drive around with an unlighted Butt?

Isn't there a law against that?

 

Thanks for the replies.. I'll give those options a try... and Yes, the lumbar support in the bottom of the seat for lower back support...when it is adjusted fully for more back support is when it triggers the rear driver door sensor... ugh - just had a coil go out yesterday too! Easy fix at least!
