Moin together, Our “little one” (see signature) stayed for the first time yesterday. There was a dense snowfall with minus 6 degrees outdoor temperature. He spent the night in the open sky, which meant that I felt I had to shovel down a cubic metre of snow from him before it started. Everything ran wonderfully until after half an hour (at the supermarket) the engine malfunction lamp lit up. In addition: No radio, no driving assistance systems, no blinker, warning blinker r, nothing. Engine was running, but my wife did not dare to drive to the workshop in dense snowfall. The ACDC then picked him up and brought him to MB. After two hours we were able to pick him up again, with the information that the engine control unit communication was disturbed. He then got an update and now everything seems to be fine again. That had nothing to do with humidity and happened purely by chance. However, my fear is the following: The snow masses have defrosted After a few hours in the workshop it is dried up again so that the error does not occur at the moment. However, according to the friendly, this possibility was expressly excluded. I do not believe in such coincidences. Has any of you ever had problems with water intake / humidity near the controllecronik? Many greetings Ingo
