Re: Audi A3 - Battery Drain

Yes it logged a fault code. Although there where loads of fault codes logged. As I remember both front doors logged can faults along with lots of other modules so it wasn't immediately apparent what was going on. All the functions worked on the drivers door, window switches and central locking operation worked as you would expect for the other doors from the drivers operation. Which is why it had me going for a bit. It was when I scoped the CAN wires at the module I found the fault. With the module disconnected I only had signal on one cable. I was a little annoyed that I hadn't found the issue quicker but that's diagnostics for you sometimes.
