I say sort of issue, because it has only happened twice in the 4 months I've owned the car...
The first time it happened it was -5 so I purely put it down to the temperature, the engine is turning over and it sounds like it's almost catching and it took about 3-4 seconds for the engine to start, usually it's pretty much straight away. This was probably back in December, then tonight leaving work it did it again, only this time it was +5 degrees... I know not exactly roasty toasty, but didn't think it was cold enough to affect anything.
Anything I could check relatively easily? Baring in mind by under-the-bonnet mechanic knowledge is pretty limited.
No doubt it will be fine tomorrow morning when I leave for work :D
