the EPC light comes on
I am going to guess that an EPC light is the same thing as a MIL or CEL and is an indication of a problem. Assuming that is true then you need to have someone check what code has been stored and what that code means
Note: Codes do not say replace this or that part, they do say that the computer is getting an unexpected signal from a sensor monitoring that part. The difference is significant.
Note2: In North America VW’s use an expanded error code system and not all of the possible codes are readable by the standard reader, so a special (VAGCOM) reader is required for some errors.
It might also be a service engine soon light, meaning maintenance is due, or ???
I believe EPC relates to with your brake pedal switch or automatic transmission sensor. Usually you are required to press the brake pedal in order to shift the automatic in a gear.
Are you actually having a problem?
