Hello, my husband’s Phaeton (Benziner, V8, Allrad, Automatik, EZ 12/2015) can always be started perfectly with the start/stop button at the cold start. However, the following problem has occurred over and over again recently: If the engine is warm and the engine is switched off, e.g. in traffic jam or during a long red phase at the traffic light, then the car can no longer start immediately with the start/stop button. Most of the time, it only works on the third attempt. In the second start attempt, it was currently noticeable that the various symbols you see in the dashboard did not light up. The battery in the key is fine. Can someone tell me the cause and the solution for this problem?
