ABS Module Replacement
ABS Module fault recorded in VCDS, and associated modules noting that the ABS Module could not be communicated with. Cross referenced the wiring diagrams for the footwell splices and checked continuity + CAN signal. Ended up tracing CAN Signal and ground all the way to the ABS Module, discovered module faulty. Brake fluid was also present in the connector. Removal and replacement involves pulling the wiper cowl, removing one ECU (the master), and the cabin air intake, in addition to a full brake bleed. Make sure you follow the VCDS output tests to properly bleed the front brakes, and re-code your new ABS module accordingly for proper communication.
