Hi all. I have an old 2001 S6 and recently replaced the voltage regulator on. Ran fine for a while and the regulator is performing correctly so don't think that the issue is related but you never know. Any way out of the blue the battery ran dean whilst parked up so got it running again only to find the 5amp fuse for the dash is fused and fuses immediately after replacing it. I was wondering if anybody knows of any common issues that might be quick and easy to look for? I read that it could possibly be the wiring loom that runs to the tailgate but not sure if that was relevant to this car and have not checked it yet.
