Cabrio Top Help

[sethmark]

Hello folks,

I am working on my 1999 C4 Cabrio and am at an impasse. The bracket that held the the main bow of the top broke. I replaced it with a simple bracket to get the top functioning again. It went up and down flawlessly, then I put the car away for a week. The battery was weak and when I went to restart the car and drop the top it failed to drop.

The clam shell opens, the latch unlocks.. then nothing.

I had the top in a middle position for an extended period when I was trying to fix it. Did I create a problem?

Is there a way to manually lower the top? What might this be?

Thanks.

Seth

You might have to calibrate the top mechanism but will need the Porsche scan tool or contact Durametric and ask if their software can do it.

Sounds like one of the micro switches missed execution. Most likely the one related to the "bow" you created. Can you shoot pics? Correct replacement and then calibration execution on PIWIS or durametric should resolve.

There's no way to close the loop? There's not a dealership anywhere around these parts and the car isn't quite driveable yet.

You can manually open and close it if you follow the emergency procedure in manual. Still will need PT2, durametric and PIWIS to execute calibration. After fixing problem of course. (otherwise waste of time)

Thanks for the counsel, guys! Turned out the reservoir was basically dry. Fluid saved the day. On to the rest of the resto.
