Wind noise
Is this the general perception? Has it something to do with the roof rails or runner boards perhaps? The noise seems to emanate from the upper side of the drivers door
My dealer is looking into getting the acoustic glass pack fitted under warranty but I have had no confirmation that MB will allow this as it is not supposed to be available on UK spec cars.
MB they claim that they have had no other reports of this issue from any other GLC owners and I am afraid that they are going to deny the problem exists as they did with the C Class.
I will keep you posted with the outcome.
