Today I wanted to replace my AGM battery. The preparation worked excellent thanks to the instructions of “Hoellenqualen” from 2013. The way was clear, all cables sufficiently laid aside. However, I got the battery only about 5cm raised, afterwards something stuck somewhere towards the rear light. I could not locate what and where it was. After 1h shake, dodge and always lift and lower again I gave up. I built everything together again to see which error messages would come and d a small round to turn. Result: outside of the clock nothing came. Windows, steering learned and clock set. Even the day kilometer counter was still up to date. As I said, I only look for someone who has made the exchange schionmal and with advice how I turn the battery and have to turn to the side of the site. Electrical / cable works everything, I have now already 1x built out and again.
