first of all I would like to say hello. I have read many articles, find the forum really great and have registered now. So far I had all inspections, repairs also made TÜV / ASU with my FOH. After the last workshop visit with annual inspection, TÜV and ASU cost 1491 Euro, I was very angry. Because due to faulty work of my FOH ́s a TÜV inspection had to take place. That is why I now do a lot of work myself. Thanks to the competence, the know-how and the instructions of this forum I have already done some repairs successfully: – read out engine code, – renew camshaft sensor, (didn’t know before that there was such a thing) – change lighting of the climate automatic, etc. Maybe I can also contribute a contribution. Anyway a friendly GLÜCK and so on, the generality needs you!
