Hello, I tried to close my Audi TT 2008 soft top

SOURCE: 1998 Audi A6 sunroof is will close only half way.

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

Had a similar problem audi come into my shop.  No headlights, blower motor would not work, wipers would not work.  After dinking around found ignition switch wires had burn't up.  Remove top steering column by taking out two very small philips screws from under column.  Look at top LH side of column w/ top cover removed.  Probably will find wires burnt up.

This is a common problem with the C5 A6 models. Before you replace the fuse for the windows (I think it's number 14, but i don't have a manual in front of me - Anyway, it's the 10A fuse that's blown!) Look under the back of both front seats and you'll see a light that illuminates the floor for the back seats. Rem ove the light from each seat by prying it out with a flat screwdriver and disconnect both leads. Replace the fuse, and your windows (moon roof and interior lights as well) should now work. The lumbar support causes something to short out the lights. I've tried insulating the lights on mine, but the problem always comes back so I just disconnected them altogether.

I have had this problem with my 2005 S4 Cab - sometimes the top will not latch. I have found that this was because the fabric near the rear passenger window was not folding into place over the steel structure. I just back up the top and made sure the fabric unfolded and all was well.
