Already replaced the osf abs sensor and checked continuity from the abs module to the sensor all the wiring seems ok but the weird thing is I get the same code when the sensor is unplugged or connected...(Short circulit to postive & Data bus missing message from engine control module) Its driving me Nuts

By the way Its an Audi A4 Quattro 2000 model B5

ABS ECU needs to be reworked. The fine wires break up causing all sorts of issues. The first of which is sporadic failure and eventual non communication.

BBA reman do them IIRC
