Can anybody help with the squeaking window? I tried wd 40 and silicone spray and nothing helps.
It is front passenger window. It started doing this after 180 km/hr run through sahara like country mountain back road.
The Audi was making 20 meters high ploom of dust so when we reached the mountain after 20 minutes and stood on top we could still see the cloud.

 

Would need a better description such as what window, when is it squeaking, when did it start, what has changed etc?

 

without knowing more, sounds like dust/sand in sliders. If that's it. need to take apart inside of door and clean sliders. Hope its not motor.
