So, after I have denied my performance, I think about installing a Rosstech adapter with VAG-Com or VCDS. Official suppliers are: Auto-Intern GmbH – Deutsch! Herner Str. 299 Building B29 44809 Bochum +49 (0) 234-58 66 422http://www.auto-intern.de/module-pagesetter-viewpub-tid-27-pid-0.html#bestrosshexusbcan MFT – Milewski Fahrzeugtechnik – Deutsch! Wilhelmstr.26-30 13593 Berlin +49 (0) 30 3628 7924http://www.diagnosistool.de/preis.html Kaufmann Automotive GmbH – Deutsch!

Full) version for the “Randmodelle” Are there any differences in the software (the adapter would have to be the same with all suppliers (?) ) The software would have to run for example PCI on Auto-Intern (is now simply indiscriminately written, is only about the principle) or? Are there other Pro & Contras???
