They aren't related electrically, but the ABS sensor cable assembly provides the wiring between the caliper and the car.



Most often its corrosion on the connectors of the pad wear connector. Cleaning them up with a tiny round file and tweaking them with a tiny screwdriver often helps. Ditto the body harness connector. A squirt of WD40 stops them corroding again.

I thought the D2 was a very simple circuit back to the instruments.
Could be a fault there ..

wow ! I had no idea ! so in effect there is a there is a sub harness with the ABS and pad wear wires running through ; in case I can't cure the problem by cleaning up the pad wear connector where do I find the body harness connector to clean it up ?

if that doesn't work presumably our sponsors could find me a replacement sub harness !

The body harness connector is behind the front portion of the wheel arch liner.

A8parts may have some sensors in stock but it can be a pretty unpleasant job to change them. Either they just come straight out, or they are seized in place and the bolt snaps in the hub. Tbh if it came to it, I'd hard-wire out the pad sensor before I changed an ABS sensor to cure a pad sensor issue.
