I have a US spec 1999 C2 cabriolet. A few weeks back when trying to close the top the clamshell would not open. It was stuck on the left hand side. After several failed attempts I sought the help of this forum. The clamshell is held firmly in place by three latches. A clip holding the latch on the left side had fallen off and hence the latch was stuck. I was able to loosen the latch and open the clamshell using the emergency crank behind the rear seats. Miraculously I found the little clip and got the latch fastened as well. So far, so good, but the clamshell is not closing or opening. I have taken out the drive motor and it is turning fine. Oddly the shaft off the motor is totally smooth and it fits into what appears to be a gear with teeth that drives the clamshell opening mechanism. I cannot understand how the motor can get any grip. Is there a clutch mechanism of some sort?

Does anyone have any experience with this problem??

On page 143 and page 149 of the MY03 Carrera Owner's Manual re. Convertable Top Emergency Operation, there is a statement that says not to operate the top normally until the car has been taken to a dealer for service. I think that the MY99 Carrera Owner's Manual has the same information.

I think the top system has to be re-synchronized following being opened or closed using the emergency procedure. It takes a PIWIS or PST2 (or perhaps a Durametric) to re-synchronize the top system.

Thank you Bill for pointing this out. Having now re-read my owners manual (which I of course should have done before embarking on this) the same statement can be found. I did try to calibrate the top with my Durametric but since the clamshell is not functioning (synchronized) it would not initiate calibration. I guess everything has to be lined up in the proper sequence. Re-synchronizing the top system does not seem to be supported by Durametric.

Does anyone have any experience in changing the clamshell drive motor or mechanism and then having to have the sytem re-synchronized using PIWIS or PST2??
