Hello, I have two problems with our Smart 451 Bj. 2014 with approx. 56 tkm. First, when pressing the key to open it flashes about 6 times very fast. With the Ersartz key normally 3 times. Second, when the engine starts again after a stop at the traffic light, the radio goes off every time, but also goes on again. These are only small problems, but disturb me nevertheless. Maybe someone knows about it here and can help.
