Rough idle and stalling

[rfalusi]

Hi guys I have a 2013 e92 m3.
I have rough idle only when the car is warmed up, but not every time sometimes it’s good.
I already changed the fuel breather and the map sensor but nothing changed, checked for vacuum leaks but found nothing.
I don’t have any codes related to this only an alternator fault code. Do you guys think it can be the icv or something else? Before I’m going to buy a new icv I want to make sure that’s the problem.

Thank you if you guys read it!

I had similar symptoms when it was very hot out and I had been running the car hard. Changing the idle control valve solved it.

Considering you are in Dubai, I would suspect the car sees alot of heat.
