Wear on the starter is the main concern here - according BMW TIS bulletin on the Automatic Start-Stop system, the starters are rated for 8 times more starting cycles than on non-ASS cars. As far as the engine wear is concerned - the very first start after extended shutdown will generate the most wear, as the oil has run down into the sump.
SS is much more annoying with an auto, because in a manual, when you come across a situation where you will only be stopped for a brief time, you can keep the clutch down and SS won't kick in, but you can't do that with an auto, you would need to reach over and turn it off. gallaghb.

The Automatic Start/Stop (MSA) system is a further BMW Efficient Dynamics measure aimed at meeting BMW's commitment to reducing CO2 emissions and enhancing fuel economy.

The other scenario, the more expensive result would be engine need replacing. If the engine timing of the cam is off, your car will either be running rough or not at all.
The Auto Start/Stop function is default set to "ON" after each engine start using the Start/Stop button. There is no way to set this feature to default to "OFF" at start up. I regret any disappointment this may cause. Driving in Sport Mode, however, will deactivate the Auto Start/Stop function."
