How do you install BELT FOR WIND DEFLECTOR - 2001 Audi TT

If you are talking about a plastic wind deflector that has discolored due to oxidation I'd recommend a polish like the kind used to treat motorcycle helmets and plastic vehicle headlights. You'll need a buffer or rotary tool - and don't forget to wear protective eye-wear.

I'M SURE THAT YOU CAN POSSIBLY HAVE A WINDOW DEFLECTOR ON A AUDI TT IS THEY DO NOT HAVE DOOR POST ON THE WINDOWS, IT IS ALL GLASS, REFRAME QUESTION.!!

air deflectors on the front doors?

no links, to actual parts.
i guess you dont know, they make many and aftermarket part and OEM parts, and all work different and all if unique issues.
after all its a MODIFICATION.
wind noise more.
why do you want them , is key?
in Alaska, or key west and no A/C?
why?
deflectors....
state a goal and ask what works best.
why not do that?

I would suggest a good wind deflector like the Zefferus windscreen or something to get rid of the bogeys of wind noise and buffeting.

Try, to find the type of wiper arms that have the wind deflector
built on it. The theory is the deflector is set at an angle that
the wind puts pressure on the wiper to push the blade to the
windshield??

OR the wiper arm hold down spring is just worn out

If you are having trouble fitting the wind deflector, try adjusting any of the four spring loaded pins. Each pin is actually a screw that can be turned to lengthen or shorten for a proper fit. Once pins are the correct length, facing the rear, insert the two pins on the left / passenger side first. Then use the springs to insert the rear / driver side pins. Last pin inserted should be the one closest to the driver seat. The large clip should extend just over the outer, right edge of the deflector.

To fold, you first need to release the pin from the upper / folding part of the deflector. This pin is on the driver side of the deflector, but on the left part of the clip. When removing / folding the deflector, grab the clip closest to the driver seat, and pull out and back (towards the driver seat). Then slide as far left (towards passenger side) as it will go. This should release the pin from the upper/folding part of the deflector and allow for easy folding.

Hi, it is the drive band for the deflector. There is a single motor behind the driver, this drive the two screws via a band. It i shard to see but when the roof is in the down position remove the trim and you can see both screws which raise the glass. The glass is seated within single metal bracket, if you feel follow the top of the screws you will find the band.

I had the same problem the glass would only raise on the drivers side then stop with acracking sound, which was the trim luckily, on inspection I found the drive band had worn away, so the motor ws only driving one side.

I hope this helps
