Hello I’m desperate about my good old 850s and thought, maybe someone can give me a tip here. I don’t know myself well (maybe it only drives because I love it so much) and unfortunately I haven’t found a decent workshop yet or someone who could advise me. My dear car got a new TÜV in August and drove until yesterday totally smooth. Unfortunately, the cooler is now worn off. The somewhat unromantic type from the workshop to which the ADAC has dragged me meant only: “Cylind head seal, the old box can be on the garbage. ????. So as I said, I’m very attached to the car. I only plugged in in in August 2000 Euro and not a good workshop. What do you think it’s worth taking money again? Maybe someone can help me further and has a recommendation for screwdrivers in the Munich area. Many thanks!!!
