Manual or PDK?

uto Start/Stop Function
When the vehicle stops, e.g. at a traffic light or in a traffic jam, the engine automatically stops, provided all the requirements for the auto stop function are met. In addition, the engine can also stop automatically when the vehicle stops while moving at walking speed. In this way, the automatic Start/Stop function helps to save fuel. The ignition remains on, even when the engine is stopped automatically. All safety functions continue to operate.

It's the dealer's obligation to service the warranty--even if they don't have a clue at present. It sounds to me like it's time for escalation, by the dealer or you if they are not being prompt in getting it fixed.

I had this same situation come up the day I had my car delivered. It has something to do with the order in which the auto start stop function is activated with relation to putting the car in sport mode. I can’t remember the exact sequence that causes that to happen but I had to call my sales rep who talked to someone in service to get me the answer.
Exceptional conditions for the Auto Start Stop function
The Auto Start Stop function is not available in the following cases, for example:
When SPORT/SPORT PLUS mode is activated.
