996 targa roof - help needed

[vtb]

Hello everyone.

I've got 2002 Targa. Today i've opened the roof (as usial) while driving to the work.
When i tried to close it i heard some "squize-squiiiiiiize-squiiiiiiiizzzee" sound from the left part of the roof (near drivers head) - it seems that roof guide don't have enough lube between it and car's body (i mean between moving roof and non-moving roof-frame fixed in the car's body)
After that the roof stucked halfway to close.

After 2-3 attempts to move it forward-backward i managed to close it.

so now i've got 2 questions

1. How's bad is it? i mean is it looks like i'll need new sunroof assembly from the dealer ($8K) in the neares future or it's just because nobody (i've bought this car recently) lubed it properly?
2. Is there some kind of manual on targa roof? for 996 or 997 as well - to understand it's construction and what can cause this issues and how it can be fixed.
I've looked thru manuals on Manuals - but there is no targa related articles (body manuals for 996 describes only coupe and convertible)

Thank you in advance.

My manual has some hand cranking info if the Targa motors fail. Not sure about 996, but assume it is the same.

Don't know about lube, but I spray all the moving bits and tracks with silicone spray from time to time, and it has stopped squeaks and creaks. Do the motors still work? You can spray silicone on most of the Targa tracks even with the roof closed, as it drops into the channel first.

Wish I could offer more useful info. May have to talk to a dealer.....
