996 Turbo.....Alarm Problem!
Discussion
Hi guys,
If somebody could give me any pointers on this, it would be very much appreciated!
I left the car for 5 days over last weekend, in the long stay car park at Heathrow. On returning, went to first use the bonnet release on the key fob, which worked, but I noticed 2 blips of the car horn / alarm.
Subsequently, when trying to open the drivers door, it wouldn't respond to the key fob, so I had to unlock it manually. Again, heard 2 blips of the horn. Putting the key in the ignition barrel, it started 1st time without a problem.
However, on approaching the ticket barrier, I noticed that the windows wouldn't respond, so had to open the door to exit the car park. I subsequently found the sunroof, the central locking button on the dash or the passenger door - from the inside wouldn't also
On the drive home on the M25, a couple of times the alarm went off while I was driving, only for a couple of seconds...but a bit disconcerting, to say the least...and looking like a bit of a prat too!
I popped over the Porsche Centre Hatfield, for one of their engineers to take a look (they supplied a new key fob about 2 months ago - but say it wasn't that, that was faulty). He did ask if I ever had water leaks internally, to which the answer was no. It's booked in with them for an hours diagnotics on Tuesday.
The car continues to blip twice on unlocking & locking and have read in the owners manual that this signifies a fault...no $hit Sherlock!
Any pointers or info would be appreciated.
Cheers,
Scott.

Put your hand under the passenger seat to see if you can feel any damp. I had electrical problems with my old 996 Carrera and that's the first thing I was told to check. If the drainage holes are blocked water can build up under the seat and get into the DME.
Cheers Bill, appreciate that. I'll check.LeighB said:
May not help but, try reclossing the storage bin lid behind the handbrake. Sometimes if it's not shut properly this can cause the double horn blips when locking the car.
I thought about that too and you're right that it would cause the double blip of the horn (I think this happens if any of the internal compartments aren't closed). But it wouldn't explain all the other symptoms: windows, central locking, etc. not working.BillTheButcher said:

Agreed Bill, but may cure one of the problems

Yes. I've just re-read my reply and it comes across as a bit arsey. Sorry, it wasn't meant to.

Thanks guys.
Hadn't heard the one about the storage bin situation. Will check both later today.
Could it be as simple as a fuse?
Unlikely. These kinds of symptoms seem to be quite common on the 996 and from what I was told they're usually down to water in the DME or a faulty microswitch in one of the door handles.Hadn't heard the one about the storage bin situation. Will check both later today.

Hi,
Have you tried using the key to lock the car, then unlocking using the key ? After doing this, try using the remote to lock/ unlock. This worked on mine one time when the remote wouldn't respond initially after the car had been sitting for a week, and I also set the alarm off inadvertently, with the two blips sounding first

The car will stop responding to the key fob after five days of not being used IIRC. You have to unlock the car manually using the key and then put the key in the ignition within something like fifteen seconds to stop the alarm going off.
It's easier than that - once you've unlocked the car with the metal key the remote will then work - if you don't use it you may set the alarm off when you open the door.angrybob said:
had the same - blown fuse for doors/windows.
20p fix...
Update...and thanks to all the guys above who chipped in with advice!20p fix...
Car was in at Porsche Centre Hatfield yesterday (after the PCGB R21 meet there the previous night!) and as angrybob suggested above, it all came down to a blown fuse, which they did FOC (thanks Chris). Now all working as it should.
Getting a re-gas on the aircon in prep for Goodwood FoS, Silverstone Classic and the Nurburgring / Belgian GP in August!
Happy motoring!
