I recently noticed that power delivery isn't as smooth as it should be. So a friendly garage let me plug the car into their VAG-COM which gave me the following DTCs:
01602-034 Electric Drive Motor
12599-033 CAN Bus
No idea if they're related to the issue I'm having, but I've searched high and low and I simply cannot find any detailed descriptions of what these codes might mean. So, before I fork out the cash and call into my Audi dealership, can anybody out there shed any light on what they mean?
