    Default DS wind noise

    Hello,1974 DSuper5, has anyone solved the problem of very loud wind noise? It is fine up to about 60mph, then it starts to chime in. Conversation is difficult at 75-80mph (I know I should feel lucky)
    Is it because the windscreen glass is recessed? Or the wing mirrors aren't moulded to the body? My door glass fits tightly to the rubber. My panel fits are 'all right'.
    Not sure where to start

    The manual advises panels to sit slightly proud of the panel behind to reduce wind noise. See the body manual. If you have it perfectly flush down the side, it's not per the book and may contribute.

    I'd actually be winding the windows down mate!
    Baked beans could be a possible cause and its difficult to part cheeks and control a vehicle at speed.

    He said 80mph ..... You are certainly going to have lots of wind noise (and engine noise) at any DS at 80mph!

    Is England big enough to wind up a DS to 80mph?

    Maybe his has the SM motor in it ... So they can get to 80mph quickly enough .... allowing them time to jump on the anchors and avoid running into the ocean at the other end of the island ?

    Hello,
    I found two sources of wind noise

    One
    The side mirrors (brand new). The cause was that there was a very small gap between the metal body and the plastic bevel which holds the actual mirror in the metal body. A small bead of clear silicon filled the gap (put on with my finger and then cleaned up with same) and eliminated the noise

    Two
    The seal between the window and the rubber door seal ( the seal is mounted on the body around the door opening).
    There is an adjustment on the doors (detailed in the workshop manual 814) to make the window bear with more force on the rubber seal. But on my car I had run out of adjustment (thus the window was only lightly bearing on the rubber). I could have replaced the rubber (which in all other respects seemed in great condition) but that was expensive and, I anticipate, a tricky installation.
    So instead I poked a piece of approx half a meter of 5mm diameter solid rubber foam tube (Clarke Rubber) inside the rubber seal on front windows only. It reduced noise by at least 50%.

    Perhaps one of these solutions will help

    Actually, 80 mph is a puny 130 kph.
    Which is the speed my 21 takes on its own if I get minimally distracted - the speedo is just over 140.
    Between 130-140 "true" seems to be what it naturally settles and is comfortable at.

    I do get a little noise at speed sometimes. Just from the passenger window. But there is a point - not quite all the way up, just a fraction less, that I can easily find by turning the handle - where the noise pretty much disappears.

    Hello, I removed the shims under the door hinges and now the front wings are flush with the doors, before the doors were 2-3mm proud. I adjusted the door glass in both front doors, and took blueduck's advice and bought some foam tube, still to be fitted. I also taped around the edges of the sunroof.
    A quick blast on the motorway at 80-85mph and although there is some wind noise, it is much better. I'll be able to hear the wife now! Damn
