Hoping someone could suggest where to go next with my A4 ABS problem.
A few weeks ago 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.
I'm a bit stuck where to go from here and would appreciate any help
Thanks a lot
