please advise
Also, I believe the W221 engages in self-leveling while stationary. It may be that the location in which you are parking has an increase in elevation at the front right side of the vehicle, so the car slightly lowers itself at that corner to keep itself uniformly level. However, you may disregard this notion if you have noticed this issue while parking in different locations with varying elevations and slopes.
changing sensors requires calibration
just measure your car on a flat floor and you might see difference
you should now do a full calibration on a flat floor
let me know if you don't understand the angle
its a kinda lottery, some work some don't as the sensors have their own calibration
Official WIS MB requires it
