Ive recently started getting this weird combination of warning sensor lights from my allroad, only happens about 1/10 times I start the car. The ABS, Air Suspension, and Traction Control lights all come on. Car didnt behave any differently. I took it to the dealer and they said it was a faulty brake sensor, and it was fixed. But im still not convinced. Any Ideas? Could it be the Quattro?

Thanks

 

I've seen this in the past a couple of times over the years. Typically occurs for me after having driven through deepish water, then braked on a rutted surface. No change in the vehicle other than the lights. My guess is that it is a temporary sensor problem and I have chosen to ignore.

 

^ totally agree - the problem is ABS sensors getting clogged with mud common on off road conditions so a good jet wash is recommended on the underside (ABS/TRACTION/HIGHT Control ) are all linked in the ECU so probably loss of traction could cause all of the issues, clean it/clear the codes and see how it goes ( and post the fault codes )

 

I had the same thing happen onceafter driving in somewet and muddy conditions.Car drove normally andit went away as soon as I turned the car off and started again.Dealer said the same thing...it was a clogged or dirty sensor.

 

oh ok guys thanks

 

I'm getting the "Break Light Error" problem - similar to the above. Each time I am pressing break, the light goes on. Did pluging to the VAG, cleared error code, do the washing :-)...but the problem persists. Any ideas how much is the replacement service for this particular sensor?

 

Hey there, I am new to Audi and my Allroad. I was wondering what the mod was that you lave listed as "20 mm spacers"? Thanks.

Good luck with your sensor and warning light issue, I hope it is as simple as a good wash to fix it.

 

Searched it....found it...never mind me.

 

All three of those lights came on. At the dealer's, they said it was a blown fuse.

I plugged in my camper, and it happened again. The wiring harness was causing a short of some sort. Took it to another repair place and again, it was a blown fuse.

Also purchased a new wiring harness /adapter (that one ended up catching on fire, less than a year after I purchased it new from an Audi dealer).

It is a 2003 AR 2.7T. Great car, but that was an interesting experience.

 

Coud be a brake light switch
