Command System SL500 R230 – CAN BUS

Hello everyone! I have had considerable problems with the CAN BUS & Command system since about 2 months (1 month after delivery. e.g. Compass entry no longer works e.g.; back mirror automatic right when inserting the return journey – no function e.g.; RESET of the command system at almost every second start. FEHLER REPORT at MB is “SEE SIDES” long. Visits at MB Fachzerkstatt every week – SEEHR, better every time my French; coffee & cake – a glass of Bordeaux or Champag ne – but in the long run my liver & my nerves do not grow out; Does someone have similar experiences and how was the problem solved with you? Thank you for your feedback dear greetings from the rainy France Walter
