Sunroof Question?

Why is it when I click the sunroof switch one time to open it the sunroof opens all the way- BUT when i click it again to close it, it closes almost all the way but stops and then goes back and stops in the middle? ( sunroof is half open) I have to hold the switch to close it, anyone ever experience this? thanks

Needs to be resynched. Just open it while holding the switch to open even after the roof stops for a few seconds, then do the same thing with close.

Also need to do what sosh said if you disconnect the battery. Same goes for the windows.

That's right, Barry. Lubing the sliders, etc are part of normal service (items 10 & 11, depending on roof type).

where do you put the lube and what kind do you use, I tried the technique that SOSH recommended but it didnt work so I think I might have to lube the rails,

First clean the rails of all crumbs/debris. You can use white lithium grease. Use as little as possible to do the job. Put it on with your fingertip. Grease attracts dirt, you know. Open the roof 1/2 way & look how the window slides in its tracks. If you're not sure let the dealer do it.

RESETTING SUNROOF:

The sunroof must be reset if the battery has been disconnected or has become discharged, it was closed manually (emergency operation), it does not open smoothly, or there has been a malfunction. More than likely your sunroof is not opening smoothly. Same held true for Barry, this is why they cleaned, lubricated, and then reset. If your car is still under warranty I would suggest bringing it back to the dealer. If not, you can see by simply fully opening (not tilting) what you can clean and lubricate to the best of your ability.

- Remove the fuse for the sliding/tilting sunroof in the main fuse box (interior driver side), reinsert the fuse
- Make sure that the key is in position 2 in the ignition
- Press and hold the switch until the sliding/tilting sunroof is fully raised at the rear
- Keep the switch pressed for a second or two
- Check that the sunroof can be opened or closed fully
- If this is not the case, it will be necessary to reset it once more

RESETTING SIDE WINDOWS:

- Make sure that the key is in position 2 in the ignition
- Press and hold the switch up until the window is closed
- Keep the switch up for a second or two

My SA at Phoenix Motors told me that it wasn't necessary to remove the fuse to re-sync the sun roof.

I had the seal replaced on the sun roof and I believe they used some kind of spray to lube the rails. I don't know what you are supposed to use on a W211 but on my 300E, there is a special (and expensive) lubricant called Gleitpaste (p/n A 001 989 14 51) that is supposed to be used. When I talked to the service department about it in Minnesota, they told me they didn't use it but used some kind of spray-on lubricant that had an Audi part number.

Anyway, I bought 500g. of Gleitpaste and have been using it for years on my cars and also on anything that slides. It's amazing stuff.

Either way, the important thing to remember is ignition - position 2.
