I've postes the Auto Scan Results below. Seem to have problems communicating with some of the modules.
The full story can be found here:
http://www.audi-sport.net/vb/showthread.php?p=709595#post709595. But as I needed some specific VAG COM help I created this thread.
In summary:
I got the orange abs lights and the flashing brake fault light up (complete with 3 beeps when starting the car).
My handheld code reader indicated an ECU fault.
Had my unit tested and it was 'unrepairable' so replaced it with a used unit. This cleared the red warning light/beep.
The orange ABS light would come on after a few minutes driving - before it did the ABS seemed to operate when the brakes were applied even a low speeds.
I re-scanned and got a rear ABS sensor fault.
I removed and cleaned the sensor (it was covered in metal particles - like a magnet and iron filings).
This cleared all the fault code and the orange light but the ABS seems to operate everytime the brakes are applied even at low speeds.
Both rear sensors have been replaced and the rings on the rear hubs checked by a local garage.
Some suggestions were that it was a sticking valve in the hydraulic part of the ABS controller or that it needed bleeding (the disks, pads, and cylinders have been replaced on both rear sides)
I bought VAG COM and have tried to perform the output tests and to follow the ABS bleeding procedure but cant seem to get them to work (see first post)
I'm at the limit of my knowledge so would appreciate any help
Thanks in anticipation.
