Alarm keeps going off when I unlock and open driver door!!!

[sprocket]

Ok, I have a head scratcher for you all.  My 2011 Cayenne S alarm is doing something weird and I think i accidently activated some setting without knowing it.    So here is what's going on:

 

When I used to lock my CS the lights would flash and it would chirp twice.  Today when I lock it, no lights flashing and no chirping!  then when I unlock it, the lights flash once, I open the door and the alarm goes off!!!  WTH!!!  Is it possible that I activated some feature?  I remember pressing the lock button multiple times on the fob in quick succession this morning when it looked like it wasn't locking (no flashing lights and no chirping).  Could that have done something?  Really annoying getting into a prestige vehicle and alarm is always sounding off.?

 

Thanks in advance.

Two-alarm chirps mean there is an alarm fault. Normally Porsche's just flash the lights on lock and unlock.

You need to check the alarm system with a Porsche specific tester for faults.

Will a durametric work for that?

Interesting turn of events.  I read another thread where the same problem happened.  He unlocked and locked the door a couple of times with the emergency key in the door handle.  I tried the same and problem solved!  It locks fine now,  chirps twice and lights flash twice.  

 

The only thing that confuses me now is that Loren says the double chirp means a fault!  The I'll get the durametric on it and see what's up.

Ok....so it happened again.  It stopped chirping.  Then I figured I would try all the doors when it's locked with no chirp.  Turns out that all the doors are locked except the rear passenger door on the drivers side.  When I pull on the handle and the door opens, the alarm sounds.  So I figure that something in the locking mechanism of that door is sticking or something.  I open and close that door a few times,  jiggle the handle, lock and unlock the child safety switch in the door...and voilà!  When I arm it then it chirps twice and all the doors are locked.  So it looks like I have it isolated.  Any ideas what could be faulty here?  Locking mechanism?  Sensor of some sort?

 

Thanks.

I had an actuator that failed on the right rear door. At first it was intermittent and the door would sometime lock and others not. It would always lock with the door not physically closed but with the latch in the closed position. I finally gave up on it and bought a used replacement actuator as the iCarScan also said it was a bad actuator. Problem solved.

 

It's a DIY to do the replacement but I really relied on ALLDATAdiy to get it done as there's lot's of steps to replace the actuator and some are not obvious.

What is this "alldatadiy".  Is it just a step by step manual?  Was there any programming necessary?  Thanks.

Sorry. ALLDATAdiy.com. It's a subscription online manual and runs about $20 per year once you locate a discount code.

 

No programming needed in my case as I made sure I purchased the same physical part number. The used one I bought was actually off a Panamera but the actuator itself was the same mfg number. I did need to swap the cables as the Panamera uses different lengths. They may now have knock offs available on eBay, though when I bought mine all they had were replacements for the previous generation.

All great information!  Thanks so much.
