Hello, I once wrote in another thread that something does not work with my SH. In the error memory it says that the control unit is defective (014 errors). Now the car is friendly and he meant that my empty Batterioen m,it the defective SH have to do, ok so far so good. In the used car warranty the heater is not included, the friendly meant the control unit alone is not available and so the kmpl. SH or heater should be changed (SH I did not because recoded). Is that true or do you also get to exchange a control unit without the kmpl SH? Greeting
