Hi there.

I have an '01TT that I'm slowly but surely reviving. A current malady is the sunroof. This may be somewhat induced by owner error... The sunroof had always works reliably, yet, strikingly slowly. I figured perhaps I could spray some silicon in the tracks and smooth things out and it would work better. Well, it sort of did. It slid back much faster, but now when it goes forward, it will get to about 1" away from closing and then re-open to about half way. I can coerce it closed by holding the button and then releasing it as the sunroof gets close to fully closed and then pressing it again to get it to close. Also, it notably slows down in closing at about the midway point of closing, but it doesn't stop. I tried running warm water to flush out and gunk in the rails and that didn't help. I also tried white lithium grease and that didn't really help either. It closes evenly, so I'm not of the mind that the track is damaged. What do you think?

 

Sorry, it seem no one here has worked much on sunroofs. It sounds like some electrical contacts are dirty. The sunroof is surprisingly easy to remove. You just need a tech manual to lay the proper procedure. If you do a Google search there are some available online.

 

Electrical contacts in the switch? I don't think that'd be the case. So, forgive me for not catching on faster but what electrical contacts?

 

I am no expert but there might be electrical micro switches in the tracks that tell the motor what position the roof panel is in. Like the micro switches that govern the rear wing position. But as I wrote I am no expert. I do know though the panel is easily removed. I have done it on several other P-car just not a 996. You just need a tech manual to describe the proper procedure.

So if you remove the panel you can clearly see if it is an electrical issue or a gunk in the track issue or both. You also might have gunky drive cable or a frayed cable causing the binding which you can access only by taking the panel out. Good luck.

 

If you need any of the sunroof parts or the whole mechanism, let me know. I removed the complete sunroof from my car and it was in perfect working condition. I only had it open a couple of times during my ownership.
