Thanks for the advice on the fuses, it just so happens that I bought five boxes of Euro fuses for the Porsche at a Trakk Auto that was going out of business. I am glad that the MB uses the same as there were no spares left in the fuse box. I try to do all the work on my cars and generally enjoy being in the garage. Since I have only owned the car for about 3000 miles, I have not needed any major service on the MB and have so far done all the scheduled service work. Give me a Porsche and I can rebuild an engine, give me a Mercedes and I assumed that I had fried the wiper motor or gears when it was only a fuse.
There is a MB shop in the northern suburbs (Winnetka) called Europa that has a really good reputation.
