FYI There is a company that sells software that allows interfacing with the VW/Audi diagnostic system, it apparently emulates the VAG1551or 1552 scan tool. The system is not cheap but should cost less than the VAG 1551/1552 hardware. I have no actual experience using this product. Your mileage may vary..... Check out their web site http://www.carcomp.com Cheers Scott M.
