Hello, I think I'm going crazy. Our 2016/2017er Plus 4 has now also caught it. It no longer starts. The immobilizer does not open. The lamp blinks. In the past it never started under 12.5 volts. Then the tension became he always needs higher 12.6 Volt - 13.0 Volt. The lamp always flashes. You can hear the starter for 1 second. What have I done? New battery Coil for the immobilizer as close as possible to the key. Tried another key: Wire from battery negative to bulkhead negative. The plug under the dash port have every time 0,2 volts lesser than the battery. The instrument from the car shows the worth of the battery. Is this a problem?
