I’ll have to assume you have an f15, for me these things helped:
1. Change transfer case fluid, and reset the transfer case.
2. I eventually had a coil go bad, and so I replaced all the coils and spark plugs. This made a difference as I suspect that I had a coil that was not firing properly. A code is only reported when ignition fails for greater than 200 cycles (according to my reading of doco in ISTA)
3. Transmission has “Neutral Idle Control” that is active in Comfort mode. This does delay slightly the engagement of the gear on take off from a stop. This can be disabled using after market flash or BMW.
I didn’t ever smoke test it, as I got it to a point that the drive was acceptable. I think the transfer case fluid change and reset had the most effect.
Good luck with it all.
