What are these modules behind the front bumper?

Parking sensors?

old world w220 and some early Japanese spec 221s had radar cruise control using one central radar, gives up in traffic = 219 ADAPTIVE CRUISE CONTROL (DISTRONIC)
later high end w221's with start stop to 120 mph radar cruise = 233 AUTONOMOUS INT. CRUISE CONT. PLUS (DISTRONIC PLUS)

And nothing on the Distronic diagram shows those bumper sensors,

the big central one is the DTR
that's not the full modules - looks like N62/1 (number 31) is in the right rear wing of the boot - even my drawing is missing the SGR's in both bumpers
