Does anyone know how to change the Cabin air filter on a 2001 Audi S4?

If I remember correctly you unlatch the cover at the top it swings down and there is a little tab at the bottom of the cover that catches at the bottom of the opening. You should be able to just lift up on the cover a little after you swing it down. There may be some wires hanging down that you have to push up out of the way to get the cover to swing down enough.

I found a very helpful pdf file when installing my filter, hope you find this helpful too!

I drive an Audi A6 Quattro and recently had to purchase a replacement filter. It cost me just over $20.

I also drive an Audi and recently needed to change the air filter in my car. I found this site to be very helpful - http://www.familycar.com/autoparts/audi/a6_quattro/cabin_air_filter.html.

TheCabin air filter protects against all sorts of harmful elements, such as dirt,pollution, airborne pollen and condensation.

there is a large round flexiable hose that goes to the engine, at the other end of that hose is the rectangular shaped air filter box, it will be made out of plastic, under the top cover of this box is the air filter element.
