Code 420641 car wont leave park gear

I have 2017 bmw 440xi
Car wont leave parking gear
It would switch to D N or R for a second and go back to park
I tried clearing code but it’s permanent I think
I also tried reflashing the car to stock XPH map still no difference

Did you ever fix it? I have same problem, as it becomes cooler at night, it happens more often on first start up. Once it comes out of park, does not seem to happen when car is warm.

Hey, anyone else had same issue, its getting colder out and its happening again. Code is 420641 Parking lock: incorrectly applied. Replaced green parking solenoid in valve body but did not help.
