I have found the source of and have a fix for the annoying whistling wind noise associated with the driver's side mirror in my '98 A4 2.8. On my car this was at its worst at 65 MPH and above.<p>I kept trying to locate the source of the noise by placing electrical tape over various gaps until I finally found it today. There's a black fairing that covers the mount between the hinge point of the mirror and the lower front corner of the driver's side window. Where the fairing meets the glass it is triangular in shape, with the "rear" portion vertical. On my car, there was about a 1/8 inch gap between the back vertical edge of the fairing and the window glass. Taping that gap stopped the noise dead.<p>I came up with a simple permanent fix, and I put together a jpeg of it to go along with this description. You can access that graphic here at http://131.107.68.28/a4org/NoiseFix.jpg <p>Go to a hardware store and buy a 4 1/2 inch long piece of 1/4 inch diameter plastic tubing. The stuff I got was clear and had pretty thick walls, which is good. Black would be fine, too, but thin-walled tubing like drip irrigation line might not work as well. It is such a small piece they'll probably just give it to you for free.<p>Take an Exacto blade or razor blade and slit the tubing lengthwise along one edge. Roll down your window and slide the slitted tubing over the back edge of the fairing. Close the window and work the tubing over so it seals the gap between the fairing and the window.<p>That's it. I took my A4 out today and just drove up and down the freeway for a half hour with the radio off and a big grin on my face. The car is like a tomb, it is so quiet. The window still functions perfectly. Yipee!<p>This may not work for everyone, as I think there are a variety of other causes, but it sure turned the trick for me and I hope it will for you, too. Good luck!<p>Gordon

Try to find this kind of stuff on bimmer.org. Good luck!

Since when do you purchase a car based on if there is<br>a website for it?????!!!!!<p><p><p>

Thank you for posting your solution. This noise has been a big irritation for me. I'll try it....

We A4 owners really love our cars, and we are very informed. Most BMW owners (notice I said most, not all) I know or can characterize, care more about what their neighbors think of them now that they have a BMW sitting in the driveway.

To tell you the truth, A4.org was a big part of my decision to leave the Bimmers alone. There is so much I've gotten off visiting this website that I would have never seen on Bimmer.org. Audi owners have pride in making a decision based on value and performance rather than status.

...is that like when grandpa used to visit your room late at night?
