Just been out in the 11 reg FL2. I had driven for a few miles so the car was hot. Stopped for about 30 mins and when I started it the whole car seemed to vibrate as the engine was misfiring badly with a very lumpy tickover. Stopped engine, took key fob out and restarted. Everything OK. Have tried starting a few times since and all seems normal. Has anyone got any ideas/suggestions?

Yes, it's a characteristic of MY2010+ engines with EDC17 ECU. The firmware, to be exact.
Many cases when this was reported.
Don't know if they bother to fix it as it is hard to guess when it will do it again and you can't prove it really happens... Also no error stored...
