I don't have vag com but have elm scan, an OBD II plug in fault code reader and reseter, not sure if it works on my wifes golf but will give it a go over the weekend, i know it works on many other cars with OBD II so can't see why it won't work, i use it on my scooby. i am in Tidworth in Hampshire/Wiltshire.
Tried at the weekend and it didn't work, may work on a newer mk4, but am looking to get a vagcom soon.
