hi, iv been bugged by an alarm fault with it intermittently going off, also chirping when locking as if something like a door
glovebox/trunk/boot was open
after me replacing the rear boot catch and swapping the alarm over with a 981 boxster I still had the fault
so its been in to porsche and they said I had a rear windows breakage sensor fault
and the sensor was in the glass, so I had national windscreens come out and they said there's no sensor in the old or new and to not bother and get it back into porsche, so off it went back to porsche and they again confirmed it would need a new rear glass as the sensor is in the
heated element and are telling the control unit there's a break in the glass hence the alarm going off.
so last week nation windscreen came out and replace the glass I no longer have the chirp and the alarm has not gone off since.
I wrote this up in case it helps anyone, I found nothing on the forums about porsche window breakage sensor apart from a cayenne which had
an actual sensor on the glass.
cheers Paul
