I just brought mine in for some idling issues and they attributed it to the JB4 piggyback tune I have...plus my Intake, IC, oil catch can ,etc. They ran some tests w/o JB4 unplugged and it appeared to run smoother. No leaks on my intake either so... You do have a brand new car so might want to rethink this whole aftermarket stuff unless it's BMW approved or the Dinan route. My 2 cents...

Just confirming, Dinan is covered by BMW warranty?
Thanks,
