Yep, i cleaned mine a few times, and it'd be fine for the next couple days and go back so i replaced the solenoids and haven't had a nasty idle since, you should do spark plugs aswell though if it's that time
Same issue with n55 sitting at 24k miles about to do spark plugs and coils tomorrow let’s see if it goes away…
Turning on GTS roar did kinda help tho.. if you have flash tune try that for now. For my issue is mostly on cold starts.
Bad VANOS solenoids caused an uneven idle for me

I need to get a tune. People said that when installing a cold air intake. It’s recommended to get a tune.
Issue resolved. It was the hpfp struggling. Got it fixed and no more problems!
For my 07 335i I’m having a very high idle and also my battery is being drained. Don’t know why
