My start stop setup has not been working since November.Was at the dealer who said, in the cold it can be that the system does not always work and the battery is too weak.Now I had the battery charged 12 hours, but still can not work, because it is not really cold yet.My car is just 1.5 years old.Had there ever been such a problem, I would be grateful about every answer.
