EPB Faults - final shot in the dark!

[Duffy]

Hello

I've had regular fault codes coming up for my S8, namely

02596 - Rear Brake Pads Worn
008 - Implausible Signal

and

02438 - Right Parking Brake Motor Hall Sensor
008 - Implausible Signal - MIL ON

which I can't clear.

I've just done discs and pads, done the full VCDS adaptation process for the pads and the function test several times, all of which has made no difference, the brake works perfectly, voltages across both calipers are good.

I've checked both connectors, both were immaculate inside, I've continuity checked between the control unit and the caliper, again all good.

Any suggestions/thoughts before I invest in a new caliper? It's only done 49K and looks nearly new........

Sir Wil, can I have my D2 back?????????
