Is this a ROW car? If so do you have the key FOB that opens the top? Perhaps you have a short or are pressing it without knowing....

I think the only thing I can think of that could be causing this (aside from sitting on the remote as already mentioned) would be a bad top controller unit. I had one go haywire on me, and it was rolling all of my windows down sporadically. The unit is a brown rectangular box mounted to the back side of the rear seat assembly. You can access it by putting the top in service position, then removing the liner carpet. You'll have to test it with a Durametric or PST-2 to see if it's working correctly, but in the short term you can just unplug it to stop the top from randomly going down.

Note, when you unplug it with the top in the service position, you'll have to manually close the top and recalibrate it with a Durametric or PST-2 when you plug it back in.

You might be able to unhook that carpet liner with the top in the service position, then close the top, then reach through and unplug it, but I've never attempted this.

Thanks for that, think i will leave it into the porsche shop and let them sort it out.

Hi Graham,

It is still likely to be the door microswitch that is faulty as stated on the PST2 readout. The microswitch is stuck in the closed position hence operating the roof as you can do when you hold the keyfob button down when you open the car or by using the door key and holding it in the door unlock position.
