Chasing this issue for 2 years now with my 190e. When the car is in closed loop and the ambient temp is low-70s and below the car will randomly stall when braking. Honestly it does not happen mid-70s and above which is super weird to me and makes it really hard to track down, can only test in the fall and winter. I can't really reproduce it either, just completely random.

Anyone have any ideas, IACV has been replaced?
