I ran a bottle of chevron techron concentrate through it a few weeks ago but zero change in issues.

Yes, especially once warmed up. If I gently creep in drive, letting the brakes drag a bit it can be felt. Slight hesitation *sometimes* at partial throttle.
Oil filter cap is pretty recent. Replaced because the center part would no longer snap in place.
On the note of VANOS- I’ve read other N5X threads where members replaced the little VANOS non-return valves which have a micro screen on the end. I have not checked to see if mine are dirty and I’m not totally convinced it would do much in terms of the idle.
