Hello dear R-community, I did a R 320 long last week and I’m excited about this car. My last one was a ML 270CDI, with which I was very happy to go under. But the R-class is something special……. I’m living in Norway and I’m looking forward to my first tour to Germany. Now to my problem… Yes, unfortunately it’s the case that I had the car for 2 days and the first problem appeared. 🙁 When I bought the car, the seller gave me such a kl a battery pressed into my hand and told me that it was defective and that he bought this new one, which I now have to install myself. He told me that this battery is going to go where the big main battery is. Unfortunately, I didn’t find this little one at the main battery,but I probably saw more that my poles are totally oksed. Now I’ve disconnected the battery, cleaned the poles and from now on my stationary heating and my compass is gone. where is this little battery and why is Webasto and compass no longer going? Would you be very grateful.
