Error and no heating
EQB 350 4MATIC -24, 20000 km
The car all of a sudden gave an error during driving, ”drive to closest workshop without changing mode”, and the heating inside the car stopped working. I was almost home so I just went home, put it in park and turned it off. It then said it must be towed.
I let it be for the night, when I tried the next morning everything worked. After a couple of days the same cycle started again but now the error message disappears before I can turn off the car, and I can just start it again without problem and drive. But there’s no heating inside the car anymore. Sometimes the fan is blowing even though I turn the car off so something’s strange.
There’s an inactive code via OBD, P1547(00) [0x154700] Boost Pressure Contr. Valve Short to Ground.
The workshop doesn’t have time until 5 weeks… anyone had this issue, what was the problem?
