Hello dear Commnunity, my car has only 1700 kilometers. BJ 24. A Mokka Edct- so a mild hybrid. Today when boarding, the engine started and it appeared “engine error”, and the gearbox (automatic), you could not change from “P”. I could not completely switch off the car to close the doors by radio key. My question: The battery that is charged by “brake” is the same as that needed for starting the car? Because it is very rarely fully charged. he uses the car for the start the normal “conventional” battery ? Maybe problem with the key ? After about 10 minutes the car went still, and after reopening also the engine started again, however this battery was almost empty according to the digital display. Next possible workshop appointment in 3 months . Maybe someone has a guess Anyway thank you for any answer. Best regards
