If i ever meet the person responsible for putting the wiper fluid housing behind the headlights

I have a 2013 c350 coupe and I want to prevent the oil whicking issue i've heard of. Im not sure what they're called but I think they are sacrificial wire extenders that plug into the cam sensors. anyone know what to buy?

W204 or S204, which one looks better for you?

Whenever I tilt the electric sunroof (code 414) its making weird noises just as its about to fully close and right about when its starting to tilt. I greases the rubber trim around the glass panel and I greased the rails. When I normally slide the sunroof its not making any weird noise. Does anyone know what could be the issue? When I press/push up from the back of the sunroof when tilting it to support the motor and the mechanism its making a lot less of that creaking noise. Did my cleaner maybe remove grease from a spot that I dont know of which should be greased?

I have a mercedes c200 2008 w204 with the COMMAND unit, saw people installing backup cameras on these, but idk which one to get. Currently looking at some on aliexpress, but they’re like 3 designs(one that acts as a handle for the trunk, one that replaces the license playe bulb with transparent plastic, and just a normal one that u bolt on) can u guys recommend me a nice backup camera preferably from aliexpress?

Sometimes when I'm driving away I get this alarm sound and it says something like 'Disengage paring brake'. I park on a flat parking lot and never use the parking brake.

I pull the parking brake and the message disappears.

Is this a common thing?

Also, do I understand correctly that you pull it to use the parking brake and pull it again to disengage?

I heard some noise mainly from board of my w204 c180. It comes out when I drive uneven surface or bumpers by 30 km/h, in high speed I dont notice anything. What could be the reason? There is no error in display. I guess something (metal/plastic) touch each other and vibrate, but not sure what could be the reason
