I have the dreaded yellow warning lights on my 2001 Audi allroad – air suspension light, esp, abs. Changed the brake light switch three times. Turn engine off – hook up computer, turn ignition on - when I scan I get the following codes:

I guess the scans are pointing toward steering angle sensor and / or ABS. Any help in interpreting these scans would be appreciated.

Hi

I assume that you found the issue.

What did you find out. Have the same fault right now

Cheers

 

looks like the abs module could be causing some of the codes
it could have failed, or there is a bad connection along the wiring

 

After doing more research I found out it was the clock spring behind the steering wheel. I found a used one for $80 and put it in - no more problems. The steering wheel is easy to remove, just make sure the battery is disconnected.
Hope this helps

Hi.

Do you have the part number for the spring?

Thanks

I don't have the part # but make sure you get the one with stability program - at least that is what my allroad needed. I got mine from Wolf Auto Parts - Audi and Volkswagen Parts
they also have an ebay store
Audi Parts, VW parts items in Used Audi Parts store on eBay!

they dismantle Audis and VW's - I have bought a few parts from them and I have no complaints. You can also do an ebay search - that's how I found these guys.
Good luck. Make sure you disconnect the battery before you take the airbag out.
