I have recently had the problem that sometimes I don’t have a gear indicator in the display and then the engine can’t be started. Where else the “N” stands for Neutral is only a horizontal line. At the same time the error message “Bremse trailer” appears. Additional error message “ECAS 03061-04”. Workshop could not help by phone and gave me the tip with I say emergency start. Will not go into it here. When I stood once in the evening and the display failed again played I was at the windscreen wiper and the display was there again!!! I have to say that the wiper has been causing problems for a long time. Switching on and off the engine runs up to 10 times. At that time a new engine was attached in the workshop, same problem. So steering pole switch according to the workshop, but was not there. Self-ordered and installed, of course only changed cables, engine ran only once. All clear, error found and switch replaced. After 3 days of rain, the same Mi The display “Bremse trailer” also shows up once in a while after a normal start, engine off and restart again, display extinguishes!! Could the error also cause the fridge to not run at night? That’s the next crap, in the morning everything warm. Oh yes, and with almost every trailer I pull (about 10 pieces to replace) the ABS lamp burns, although some are only 1 month old. Hard to mention that even the heater is not very good at all. At that time it was also dismantled in the workshop, glow candle and flame monitor was renewed, everything was built in and the same error as before, runs briefly and goes out again. Workshop now taps on control unit, costs only 800,- Euronen!!! Almost a new one for!!! Meanwhile the font in the display of the heater dissolves, can read almost nothing and the flame symbol is also gone. Vehicle is year 06 and has run 400tsd, so just entered. I was curious what comes to mind.
