Went to drive home from work yesterday and the "EPC" light came on, followed by the engine sign, thought great, just what I need. Took it to Kwikfit to have the code read only to be told they couldn't get a proper reading from it and couldn't clear the fault code. Then took it to my friends garage who has a very nice £9k snap on VAGCOM system, he managed to clear the fault, but as I turned the car back on again it came up again, but just the EPC light not the engine light.
The error code is 01537, which after googling appears to be a battery issue! Hmm
