Cayenne S. Alarm keeps going off
It shows the back glass open and The ights come on when driving too.
We have closed it and sometimes several trips are ok.
Then its back on. Alarm can go off 3am or 7pm.

I think its to do with a faulty switch
Any help would be appreciated
Porsche have had it and found nothing wrong but i dont think they made much effort. Meanwhile itsa real pain in the ar--
