Bumper off - Do I need to recalibrate sensors on STAR

[Slartibartfast]

My bumper is coming off for some paint work. The car is a 2015 SL400 with standard cruise control and parking sensors. Do the sensors need to be recalibrated on STAR after the bumpers have been reattached? I think Distronic+ needs this but unsure about just the sensors. TIA

No. I had the bumper off my SL to change the grille, just check that all electrical connectors are separated. Good luck.
Ps. Watch the clip that's just below the back of the headlight
