Are there any codes to read from the computer?? I guess it could be spark-knocking but it's hard to tell on VW's until you just take it to the dealer. We just traded our 99 Passat because one thing after the next was going wrong. It started to make a knock after we just serviced it so we just freakin traded it. It was quite a headache owning that car, especially since our local dealer couldn't get the car in for service for at least 2 weeks every time we had a problem.
