I'm having rough idle issues with my 2011 318d N47.
Starts and drives fine. Once the car has warmed up after 10 mins the car starts idling rough where the revs are bouncing and hunting. As soon as I give it power or let out the clutch a little the revs rise and the engine runs smooth again. The rough idle will go away after a further 10 mins, like it was never there.

I've checked for codes on ista, I don't seem to have any, all green.
Not sure what it could be, been bugging me a long time now.

Thanks.
