Thank you Snowdriter for your response. The electronics of these cars today is mind boggling  and the interconnected dependence is tough to figure out. I have been focusing on the passenger latch but it makes more sense that the drivers door which under goes probably 95% more opening than the passenger door is the place to start. Thanks again 

I have a 2008 Porsche Cayenne S with door alarm issues. The door(s) do not recognize whether they are open or closed. This image on the instrument panel shows a passenger front door ajar icon and the beeping alarm is enough to made a sane man or woman drive off a bridge. On the driver side over the past year I have noticed the door open or key in ignition alarm come on or not, the red door lamp not light, and the interior lights not come on when opening the door. On the passenger side i have experienced the alarm icon and alarm on continuously while driving, the interior lamps staying on after the doors are closed, the signal not sounding when locking the vehicle with the remote, or the security alarm suddenly going off a short time after locking, and probably a few other annoying items. I have applied the quick fix canned air and WD-40 to the passenger door a few times and it got me through the winter, but not any longer.

So I was about to tear the passenger door apart and try and repair the latch when I started thinking it might be the driver door, which obviously has experienced a zillion more opening and closing than the passenger door. My question is, is there a separate door ajar alarm icon showing on the dash for each door, or only one showing the passenger door ajar for all door open errors? I l have only seen the Passenger door icon warning.

When I leave the key in and open the drier door there is no longer an alarm, and the red door safety light in not lit. When I manually move the door catch one notch up, the alarm sounds and the light comes on. When I move it up another notch to full lock the alarm quits and the light goes out.

I apologize in advance the length of this post but it seems to be a common issue.

I have a 2005 cayenne s. The PCM had been working fine up until the last few months. Nearly everytime you get into the car now and start it up the PCM comes on however the SAT NAV, AMPLIFIER and PHONE will not work.

A message stating

SYSTEM ERROR

PHONE, NAVAGATION & AMPLIFIER NOT AVAILABLE.

I spoke to the specialist at my local Porsche dealership about this and he said he would need to get the car onto the diagnostics to identify the fault.

I arranged to bring the car down to him when the fault appeared again.

As i stated this problem occurs nearly everytime you get into the car, however there are times when you get in turn the ignition on and the system works ok.

On three separate occasions i brought the car down to my local porsche dealership when the fault occured, but on each occassion ie ( after i got out of the car, locked it and went into find the service manager and came back out to the car) it had reset and was working. Making me to look like an absolute twat.!!!

Last week i was able to get the car onto the diagnostics when the fault occured. To my surprise and the service managers surprise no faults were being registered, even though the system error message was clearly visible on the head unit.

Stephen the service manager spoke with the head service specialist at the dealership and he said that in his opinion he thinks the problem lies with the BOSE AMPLIFIER in the boot.

Of course an AMPLIFIER isint cheap £800 fitted i believe, and this mighnt even been the cause of the fault.

Stephen therefore said he would speak directly with Porsche in Germany and the UK to see if they had come across problems like this before and whether they would be prepared to provide an Amplifier on SALE OF RETURN. IE if it isint the cause of the fault they would let him send it back.

To say neither Porsche UK or Germany were helpful is an understatement. Both said they had never came across this problem nor would they be prepared to provide an AMP on sale of return.

The fact i paid £58,000 for the car and have had it serviced and maintained (at great expense) through Porsche doesnt seem to matter.

I now have the choice of putting up with it or paying £800 for an amp with the real possibility the one i have is not causing the fault.

I am therefore looking to see if anyone has had problems like mine with their PCM, what caused the fault and how the fault was diagnosed.

Or even any ideas as to what the fault might be with mine from what i have said.

Good day. I came across this little piece of heaven yesterday after experiencing the very same problem described above. I own a 2008 Cayenne S. It had occurred maybe four times over the past two years but only for the duration of the trip. When I next restarted the car everything worked. This time not. For two days I heard nothing but the wind whistling over my ski rack (that's another story) and was not happy. I live 2000 km from the nearest dealer and when I called and described the problem, they "suggested" I call the audio specialist down the street. I googled the error and found this site. I ended up pulling the #9, #10, #11, and #12 fuses from the passenger side panel, cycled the locks, and waited 10 minutes. When I installed the fuses and turned the key everything was back. So far so good. I believe the issue is software related and the system gets hung up like a program or mouse on a computer. The system needs to be rebooted and involves more than recylcling the ignition. The latent power in the system needs to be removed just like a computer. Thanks again for putting the smile back on my face. I am your newest member.
