I recently bought brand new A150.When I drive over 120 km/hI hear wind noise from the driver's side door.It sounds like driving with open window but everything is well closed prior driving.Anyone with the same problem?

-Sorry, this is a baby merc, it IS a bit noisy! But if it's too bad, check for twist on the doors/ or bad door hinge(The noise can be from the back door as well). Check the door gasket also. To do this, use an ordinary A4/letter paper to put between the door and car frame - close the door and see if you can pull the paper out without braking it. If it break, the gasket are ok, if it can be pulled out easily, there is a problem with the gasket. Do this trough the hole door frame.
