Today I left my car on idle for 20 sec while I checked something in the flat, and when I returned I found the engine was off and there was also a smell of oil or petrol i am not so sure because I hurried to work with my other car...I remember I then tried switching the engine on in two short bursts (the instrument indicators lit up and went off as always and as they should...not an indication of any error...). The car was cranking but no joy I pushed the car back to parking lot and found a smallish wet circle on the asphalt under where the engine was...Again not sure if it looked more lika a petrol or an oil blot...Maybe more like oil. It also seemed to me that the area around the injectors was a bit wet...But again not sure....Any info is welcome. Will try to provide more clues tomorrow since it is quite dark now....and I am still at the airport where I work...totally pissed...........What could it be
