porsche cayenne 957 alarm keeps going off after locking

Recommended Posts

Hello, I'm wondering if anyone could help me. I have an 09 cayenne s with the same problem, alarm goes off everytime I press the lock button. I tried pressing the interior alarm button and also the button by the driver seat but no luck. I saw a video about fuse #34 on the driver side dash but that was all good. I've read other treads and some people mention it could be a battery issue? 2009 cayenne S with 131000 miles. Please help

Mine did it once (2005 Turbo) but only after I was in bed several hours.  Narrowed it down to the rear glass was popped for some reason.  Once I closed it up and made sure it was secure, I haven't had an issue since.   Just something to check

I had the same problem on my 09 Cayenne S when the vehicle was still under warranty.  It would randomly activate the alarm when I would lock the doors.  According to the dealer they replace the alarm control module.  It took two visits to the dealer for them to figure it out but once they changed the control module the problem went away.
