I'm getting warning lights for ESP, brakes and air suspension along with the single long beep. Adamss24 scanned my fault codes and recorded the ABS controller fault. Does anyone know where the ABS controller is and which type it is on an Audi allroad C5 2.5tdi 2002? CHEAP ABS Module Repair for Audi have posted some notes about the different types. Would i be correct in saying allroads have the Bosch 5.0 / 5.2? Taken from their website "...If your Audi has ESP and does not have a 5.7 module, it cannot be repaired. We currently only repair integrated units (where the control module and pump are located together)..." I had stupidly tried to use my rear wash during the snow storms and must have popped a connection. I don't know if it's in the hatch or under the carpet. Question. Has the leaking screenwash soaked the ABS controller and have the contacts corroded inside? If it's a Bosch 5.3 there's a video on YouTube of a guy soldering some wire to a couple of the contacts. Anyone attempted this on their own unit? How hard can it be? Some of the recon firms can turn it around in a couple of days. Thanks in-advance.
