Hello, all together, can someone tell me if the start-stop function (SSF) is like weather or temperature dependent? Yesterday I drove about 25 to 30 km and about an hour later the same track again and the SSF jumped briefly to green, but almost immediately back to orange again. We had it yesterday -6 degrees. Today morning -10 and my 28 km at work the SSF remained on orange. However, now it is noon 0 to -3 degrees and suddenly it jumped and stayed on green. I had already at 1 degrees the problem that it was bad and sometimes only on the 2nd attempt. Search for the cause. Battery has been changed due to this problem in Dec – but did not bring any improvement. Yesterday it looked at a body builder. He said that everything fits: alternator, engine, cable, battery….. looks all top…. The engine was also exchanged last year… Thanks for your answers!
