On the plus side the latest systems are worlds better. I drove 2020 m340 and x5 and it was much smoother. Add fast forward to this year and the 48v mild hybrid in the 2021 B58s and I couldn't tell other than the engine sound it was there.

However on my f30 6mt I did find I would just hold the touch down at stop lights more often just to leave the engine running if I forgot to disable
Sounds like my next car will be the first I’ll have to get coded...
