Hi all, been a mechanic few a long time now but mostly worked on old agricultural stuff, so I'm fairly new to the ECU stuff but I'm learning quick, I don't have any issues with my MK5 FSI at the moment and I do have access to a Ross Tech scan tool. What I have fixed so far is the front door wiring on both sides - doors intermittently would not lock. Will be putting on a towbar this weekend. For those that don't know the electronics that come with the towbar is just a 5 circuit relay, the box takes power from the fuse box and sends power from there to the trailer instead of using the cars light circuits. Will be good to get out in the garage again.
