Hello dear community, I bought a Mercedes E350BT convertible with 252 hp in my dream equipment a few months ago. When buying a car, I always pay careful attention to the history and documentation – also in this case. According to Mercedes-Scheckheft (digital), the vehicle was maintained every year, from 2014 to 2021. The last service was carried out at almost 100,000 kilometers. In addition, I had a Mercedes employee print a damage report, the plausible The most recently reported mileage in 2022 was almost 120,000 kilometres. In addition, a sales advertisement from 2017 was in the documents, which comes from a Mercedes dealer and indicates a mileage of almost 40,000 kilometres. I thought everything was fine because the vehicle looked good and the equipment and the price were very good. That’s why I bought the vehicle privately. After a few months and 12.00 The engine indicator light (MKL) lit up 0 kilometres driven, although the vehicle was still running normally and had no problems. I directly connected a diagnostic device and read out the fault memory. In the error memory there is “U0100 – communication error with the motor control unit”… The main kilometer level at the first occurrence of the error is 442.352 kilometers. In addition, the battery voltage indicates 25,47 V. But should the charging current not be a maximum of 14,4 V? I h abe attached a photo. Can this be only a display error at the main kilometer level? Should I be seriously worried? The vehicle has now according to display 142tKm down.
