Anyone having issues with the alarm on their 992?
Ours will have no issues at all, but occasionally you lock the car and approx 30 seconds later it goes off.
Had no issues with it for the last 10 days, yet it has gone off twice today.
Any suggestions or is it a return to the dealership?
 
Dealer had the car in and could find nothing wrong, no error codes etc. But the car will behave itself for periods of time but then go into a period of alarm activations.
The monitoring company must be getting fed up with this.

mine is doing the same. Been a few weeks ok but started again today.


Thought it may be a GPS / tracker lost issue but VF say it is an intrusion event.


need to get it sorted though as it is a real pain.
 
I've been out in my 992 for a couple of hours today, stopping three times for 10 mins or so.

When I got home I realised that I'd forgotten to take the security fob with me. I've just phoned Vodafone Automotive and they can't see any evidence of it going anywhere. Looks like it's back to Porsche Leicester, again :-/
 
Ok, car went back in for a few minor things to be sorted and we raised the issue of the sporadic alarm activation again.
It was the young lady on reception who came up with the reason why it keeps going off. She asked what kind of areas is it parked in when it goes off? She puts it down to poor mobile phone coverage. The car loses its link to Vodafone and therefore activates the alarm. Makes sense when you consider we have poor coverage where we live and some of the other areas where it has been parked.
 
My 992 S Cabrio is constantly having problems with the SOS error message. On two occasions I have driven to North Wales and both times when going over the Snowdonia mountains the SOS warning light inactive message has come on. On the first occasion it was continually on for approx three days, then cleared when I was driving back into England. However, on January 5th it came on, again in the Welsh mountains, but has not cleared, even after almost seven weeks driving back at home and pops up everytime I start up. Its now getting quite annoying. I assume its something to do with connectivity or a poor signal.

Its booked into my OPC on 3rd March so hopefully they will be able to cure the error.
 
I've also had issues with the alarm going off sporadically - always just a minute or two after locking it. The poor phone signal is a real possibility - it's often when I park it in an underground garage. I've asked the dealer to see if they can confirm that makes sense.
Just another issue to mention - the My Porsche app on my iPhone hasn't worked since I returned home after delivery (but it had worked at the dealership whilst picking it up). The other online interfaces did work fine through web browsers. I had some chat with the Porsche Connect Support team a month or two ago, but then they went quiet. Yesterday they updated the app and it started working!
The car continues to be fantastic...

I have a 992 Carrera S - been having issues with the alarm going off here at home about a minute after I lock it. It’s been to the dealership twice now - no issues found with the car which otherwise is fantastic - they do believe me as it went off the first time they bought it back! We have very poor mobile service where we live. I don’t remember it going off anywhere else.
So this lack of signal theory makes a lot of sense.
Or the car has an aversion to the gravel type we have here on our drive!

So what can we do ???
 
Well, I'll keep on at the dealer for a response - surely someone, presumably in Stuttgart, can figure out if there's a link. The dealers must want to know because it's a hassle for them if they get cars back to fix, and they can't. If it is this, it's presumably when the alarm triggers on after lock (I could believe there's a slight delay for various reasons - the car does spend some time shutting down it's systems). It's either that or some voltage dip for the same reasons. To prove it's signal related, presumably you could go through a trouble shooting exercise of removing/disabling the in-car SIM etc. I'm not sure I have the time to do that at the moment. Interestingly, I don't think I've seen anyone mention it on the Rennlist forums - maybe it's UK only? And, it's not actually triggered for a week now!
 
Mystery solved. Apparently the default setting by Vodafone is that if the car loses connection with Vodafone then the alarm is activated. Vodafone are contacting us next week to change the setting so if it loses signal rather than activate the alarm they will send an alert to the mobile phone instead.
 
Oh please please please(!) share how you got to this very positive sounding conclusion?
My 992 Cab just spent over two weeks in my OPC; with no fault found. Alarm indications were "Intrusion alert” (Vodafone) and "Interior sensor” (Porsche).
But ... I park in an underground car park and Vodafone signal is weak in the area too. They did say the car was in contact, but it may still glitch if signal strength is low or interference occurs (ie aircon pumps right behind my parking spot!)
Do I need to contact Vodafone or OPC to get this setting changed?
abz2 ... you could soon be hero status!
 
Car went into Solihull to have a couple of niggles sorted and a software upgrade. We mentioned the alarm issue again and it was the young lady on reception who mentioned about loss of signal so the dealership contacted Vodafone tracking. I will give you an update once Vodafone have contacted us the beginning of next week.
Hero status ?? It was annoying us as much as anyone, particularly when you can’t lock your car in your own garage.
keep you posted.
 
Well I never heard back on the Vodafone connectivity issue - but here is where I am at...
Gave the car to my OPC to investigate, but no fault found.
To do *something* the OPC swapped the interior sensors, as all my alarm events were "Interior alarm".
I also park underground, and in 99% of my false alarm cases, it is when parked underground.
My arrival process also includes 3 speed bumps, a barrier, a few stops and turns - and the engine stop/start would kick in maybe 8 times before I left the car.
I now use Sport mode to disable start/stop before I park (still underground).
I also wait until my keyfob gets a signal back from the car and flashes red a few times (a few seconds after pressing Lock) before walking away.
And ... touch wood ... for the last 10 days my alarm hasn't gone off that I know about (and Vodafone haven't called me).
I hope this helps you out, even though I don't yet know which changes in my car / routine is involved!
 
I'm having all sorts of issues with my alarm on my 992 Targa 4S ever since I purchased it in January 2021. It seems to go off every now and then approximately 2 minutes after locking the car. I always receive a message to say it's the interior protection alarm that has been triggered. The car has been back to the dealer numerous times to have this issue looked at and they have found no issues with the alarm each time and are baffled. This is now ruining my experience of owning the car. The issue has now been escalated to Porsche in Germany. The only workaround that I have found is to deactivate the interior protection when activating the alarm. This is done by pressing the lock key on the remote twice when locking the vehicle.

I also am having alarm problems with my 992 Turbo S. The symptoms are identical to yours and are also affecting my ownership of the car and drawing unwanted embarrassment too. Again my OPC are baffled by the problem, particularly as the problem is intermittent. One thing I have noticed is that it only happens after a drive when the engine is still warm, never when cold. I can unlock and lock many times when cold with never a problem.
Further more I have unticked the internal sensor and tilt sensor and it still does it.
I also have a Macan Turbo parked next to it which has never had a problem.
Hoping for a resolution SOON!!!!!
