Road Noise
Finally got my c300 Sport last week and it drives great. i will post pics of it soon. Took it on the highway the other day and noticed it sounds like a window is cracked open when driving. Definitely more noise than my other vehicles. All windows were up, doors were closed, sunroof was closed. Im going for a couple hundred mile drive tomorrow and will try to pinpoint it but most likely Im gonna have the dealer look at it. Any ideas? Is this normal? Just seemed like too much road noise to me especially since I don't remember the test drive being like this. It sounded like a window was not all the way up. Everything else is great. I love taking turns at 40 mph :)

The big mirrors are most likely your problem, they tend to make a lot of noise if its windy outside. Other than that you might have a bad seal on one of the windows or doors, but I'd go with the mirrors first.

It's a known issue with the W204. I brought it up with my service advisor on our A-Service and he said MB knows about it but there isn't a TSB out for it yet. Our car has done the same since day one, happens at about 68-70 mph.

What the he77... I thought I was the only one. :X I kept thinkin to myself how this is one of the loudest cars (at highway speeds) I've ever ridden in, but people kept saying this is their quietest car ever... I thought it was just me.
Now I kno I'm not :crazy: |
They should have mounted the mirrors lower, on the door.

When I first picked it up I heard a wind whistle from the drivers rear door area. Wife and daughter couldn't hear it. When I brought the car in for the 1000 mile check up I told the SA about it when I picked up the car he told me they had to do a minor adjustment to the drivers side rear door no whistle now.

any complaints about the mirrors - blame the euro-safety-crats for mandating them, along with the foolish upright grills designed to "save" pedestrians from impacting the hood.
