I couldn't neglect squeaking noises and my car did loads, especially on paved or uneven roads. I thought it came from the dash and found myself pushing the dash to see if the noise went away. Then I thought I heard it come from the windshield and they told me it was glued, then from the struts.
How many P-guys changed their wheel bearings only to find it was the tires generating the noise?
To my biggest surprise, all these squeaking unbearable noises vanished when I changed my windshield, but ONLY for a month or so.
Then I discovered the source. It is the rubber joint around the windshield that squeaks against the body. You can lift it easily from the outide, as in the picture, and I found calc deposite all around on the body paint where the windshield rubber joint touches the frame. After polishing that of with a fine carpolish, and waxed the surface. The noises came back a month later.
The latest remedy I found that lasts for about three months is to go to your nearest tyre repair shop. They have tyre soap that they use to mount the tyres on wheels. It is usually in a bucket with a brush and looks like white margarine. Just smear the brush in the soap, lift the windshield rubber seal as in the picture, and plug the brush inside. Now slide the brush always underneath the joint, and contour the windshield. Apply more soap for every quarter of the lenght, so four times.
Now take a clean cloth and remove the excess soap all around.
I must admit I need to do it less regularily now that I have installed a strut bar.
If it works for you, please tell me about it on this thread, I need to know how many suffered like me.

Pedro's Ice Wax, available at most bike shops (at least here in the U.S.) also works well. Most report it's effective up to 6 months or so.

its sadly a never ending battle... I just ignore it for the most part... and has anyone else ever noticed that once your doing 80mph, it gets quiet again.. lol

I have heard that Pedro's works great. The new windshield went in last week and it is time to get some Pedro's before it starts to creak.

One advantage of owning a Cab. The whole frame flexes and moves with the window so there is no windows creaks.

I tried Pedro's (and it was a pain to find the stuff - I called or visited a dozen bike shops and no one had it; I finally ordered it online), and it made little or no immediate difference. After a week or so, the creaking diminished slightly, but it's still there. I guess the stuff worked its way into the seam. I'm still looking for a better solution.

I do not know about pedro's, but after I polished the surface which was PITA (lifting the seal with one finger and polishing with the other hand) I put some carnauba wax and it worked for a short time. I must admit that if you wax the surface, the calc comes back. Under the seal, there is a deep water groove. So mixing water and wax (and air while driving) hardens the wax.
But the tyre soap is greasy. the more you expose it to water, the more it softens. And after a while, there is no deposit between the seal and the seam. Its really neat, try it. Advantage also is that it washes away with water and not messy.
The area that need most is the seal part next to the wipers axles.
But do not put normal hand or dish washing soap. it will squeak more.
Its a two minute stop at a tyre shop. just guide the brush with a finger under the seal and do the contour.

If the windshield is installed properly that gap should be filled with an insulating caulk separate from the normal adhesive that you use to bond the windshield.

You can pull off the black seal, no PITA. It is sticked into a gap in the black plastic frame surrounding the glass:



I have never tried out tyre soap, but this sounds like a great idea.

Other option is silicone spray.

I believe these illustrations are taken from the Porsche repair manual. Strangely these fillings are not applied on my car, even though the windscreen was replaced last year at Porsche Stuttgart.

There is a rubber foam cord available from Porsche, which is actually designated for the 996, 996 541 903 00. Nevertheless it fits into the gap between body and glass and can be soaked in silicone spray, for instance:



Best regards,

My windshield was replaced at Porsche Dusseldorf and the fillings are NOT applied on my windshield either.

Danke felix for the idea and part number, I will try it...

Edward

The fix that worked for me:
- Pedro's Ice Wax about every 6 months

The following maintenance keeps the squeaks away:
- Keeping the windows down and the RPMs up
- Turning up the radio

Supercups. I can't hear a thing.

Dealers/OPC in the USA don't follow the directions from Porsche either. I spent over a week fighting a dealer and my insurance company to have my windshield installed properly. The dealer has been around for I don't know how many years and had never bothered to read the instructions from Porsche, not even once. They finally agreed that if the factory went to the trouble of adding the pages to the workshop manuals for the front and rear windows and sold the supplies then there was probably a good reason for it.

Feehliks

Thanks for the comment. I have made further inquiries and might actually apply the filling by myself. I will tell you about my experiences.

My rear screen was replaced more times than I care to remember and the front has just been done, I had to ask for the front to be done by the manual and they still did not get it right, although they tried.

I am going to add the extra filler myself to the front and rear.

BTW - Silicone fixes the squeeks but can make a mess.
