How do you remove the sun shade on the sunroof of a 1996 Audi A4?

You must remove the entire headliner and unbolt the sunroof, it a pretty big job. If you can find a shop that will do a new headliner and sunroof cloth for $200 it's worth it. If you don't shim the sunroof when rebolting it you'll get air leaks on one side or the other.

Try sunroof switch. Common problem. They are also color coded.

The cables are worn and the motor is slipping...it will need to be removed and adjusted.

Check for any obstruction in the rail.

Also, can check this procedure to test your components...

Hope helps (remember rated this help).

roof has manual crank.open small cover on roof linning just in front of centre of sun roof and crank closed with 3 allen key usually kept inside fuse box cover.

there is a part of the shade jammed in the track if you remove the piece is jammed it will work properly

i had an audi and it cost me like 150.00

make it go back to the open position,look down the side of the tracks in the roof that the sun shade slides in and you will probable find the guides for the sunshade are jamming up the tracks. only way to replace them<4 one in each corner> is to remove the glass section and then close sunshade that will give access to the 4 guides which are available from dealer as a kit

Somewhere on the roof of the car, in front of the sunroof, you may have a small plastic square (my 99 A4 has this). Open that up and there's a screw-drive setup inside that you can turn to close it manually. If your car doesn't have that, it may be up underneath the map/dome lights on the headliner.

I'd need as much information about anything related to your driving observations to being to try and diagnose the driveability problems, but the sunroof is an easy fix, as this is a known issue on the A4. Here's a step-by-step procedure with pictures that will show you how to fix it easily:

Let me know if that doesn't work (I bet it will though).
