Did not work
Double checked for fitment and it says it’s the correct part for my Mercedes w212 e350 Bluetec but installed it and does not work. It looks like a nice part but does me no good of it doesn’t work. FYI - I double checked connection was good and even replaced and tested my original part which is still working. Had to return this one. Maybe I just got a bad part but not willing to give them a second chance.

Shedding light on the problem
The switch fits and works just like it should. Not sure if mine was a bit faulty but the backlight always seems to be on unlike the Mercedes genuine part it replaced but for $34 who cares?
