Hey everyone,
So I’ve been reading up on the wiper noise on these vehicles. It sounds like most of these have been like that since day one. My situation is that this just started about a month and a half ago. Like most everyone here I’ve cleaned the windshield, replaced wiper blades, talked to Mercedes about it ( which they were more than happy to sell me some sort of windshield cleaning service for $250 &#128545
I’ve heard that some folks have had luck with replacing the entire windshield (maybe someone would like to chime in on that). Has anyone attempted to replace the wiper arms or adjust them in any way?

thanks
