Hi, I have a 2009 A4 sline saloon B8 and can not remove the break warning light from the dash. I have tried to bridge the wires from the sensor on the hub but believe i have a break further up the loom. Does anybody have a wiring diagram or info on where i can trace the pad sensor wire into the vehicle and add an earth strap to ground it and knock the light out. I have seen this done on the older B7 models but my loom is different and without wiring diagrams i can not trace the correct wire. Thanks.
