Radar Sensors Dirty Message
Recently bought a CPO 2020 GLC43 (early June 2023). Mostly love the car, but I keep getting this annoying pop-up message that my “Radar Sensors Dirty” (forget exact wording).
I’ve looked it up in the manual and it says to take a damp cloth with mild soap and “clean the sensors”. I’ve done this several times and yet I still get this damned message.
one note: while cleaning the radar sensors I’ve always been gentle, but firm. The first time I cleaned them I noticed one of them easily gets “pushed in”. I’m thinking maybe that one isn’t properly connected anymore?
I work from home so I don’t drive often which is why I haven’t been quicker to get this resolved.
any help/thoughts would be welcome but I’m thinking it’s time to go to the dealer… just hope this is something that may be covered under CPO.

ugh, just don’t want to be without my car for any amount of time, let alone a full week, but hopefully if I mention this it’ll quicken them just updating the software.
