I have a simple question to all MB engine gurus here:
I was recently at the dealer and they forgot to install 2 screws that hold the black piece of plastic on top of the E420 engine. When I came back the service manager just said they were not important and besides they can't find them anymore. How important are they, I noticed that the air filter box outlet goes into that cover. So with the back of my cover not being tightened down, will dirty air get into the engine?
Also, where one can buy the screws that hold that cover down?
Thank you in advance. Alex
