Hey all!
This is my first post. I need some help with my car, it’s a w205 2020 C43 AMG. The problem’s this: intermittently when I throw the car into reverse ALL of my sensors light up red (usually happens on hot days). Ofc it happens right after my warranty expired. So far I know “parking sensor 3 has a malfunction” but idk why it would trip all my sensors especially since when I park my car that sensor just doesn’t detect anything in front of me. Here are my thoughts.
-Try replacing sensor 3 (but do I have to recalibrate the sensor)
-Check the wiring harness for corrosion or irregularities (don’t know the location)
-Worst case could it be the module that controls the sensors? How do I go about that?

Any help is appreciated


Here I am in drive.
