Let me help you with the translation for "Crack the Code": "All of our mechanics are dependent on computer diagnosis. Nobody here actually knows how cars work. We are parts replacers, not mechanics." Finding good mechanics can be very difficult. That is a good reason for getting to know people at various VW clubs. They may be people who work on Beetles or at least may
know people who work on VW's. One of the standards over here in Ontario is to try to hook up with the retired VW mechanics especially the ones who came over from Germany in the 1950' s and 1960's. Failing that, go to a good general auto repair place and talk with their oldest mechanic. A lot of them love to get their hands on the old stuff and may even do it after hours. Best yet, get a few of the better books and buy a few tools and get into it yourself. These are simple cars which use basic technology. You really can do it yourself.
