"I replaced my radio and now Ihave the problem with the alarm beeping when I lock the car.
Leading evidence: 'Replace radio and now ihave the problem' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'sourcing' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace radio and now ihave the problem' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Perhaps the alarm portion changed when theywent to the MOST bus system?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

There was a guy at this Car Toys years ago that has worked on all my Porsches in the past...
My alarm has been routinely falsing after about a hour after shutting off the car and at crazy hours doing the night (multiple times). Has any had this problem and got a fix?
I believe there is a wire that often needs better insulation, for the life of me I can't remember which one, I think it thinks the stereo has been removed/missing.
OK, It's Brown with a Blue Strip and called the Alarm Wire or so I'm told you can also put some real sturdy tape on the left side of the new radio in the same spot as the plastic pad on your Becker unit was.
I tried posting a link to another thread on another forum but it has to go through a mod first. Hope it helps.
There is a good thread on this on
www.renntech.com
In summary there is a metal tab on the left of the radio housing which is connected to the alarm. This in turn is connected to the alarm module.
You need to remove the radio (in my case I had to remove the metal radio cage to access this tab. Insulate the tab as mentioned above and you should be good to go.
I've had out of the blue alarms a couple times when rain starts then once I left the windows down a little and had just started walking away when the alarm went off. I think the IR sensor on the dash can pick up little things like heat waves of wind or sunshades moving a little. I don't think I'll ever try having things hanging from the mirror.
Still on alarming of the car theme. When I am locking the car via the push button on the key, I double click it and then get a short beep from the horn. I take it then that the alarm is set up. Correct? Or is the horn telling me that something is not working correctly and that the alarm is NOT set up? Thoughts on this please.
If you get a beep when pressing the fob button once, then yes you have an alarm fault. Could be: door open, trunk open, frunk open, glove box open, center console open, radio fault, or some problem with the alarm module.
One push on the fob locks the car w/alarm. Double click will lock car w/ alarm....but....turn off the inside movement sensor. I have to do this when I have my dog with me.
I think my problem maybe the stereo wire issue. It will false even if I do the double click on my remote to disable the internal motion sensor. I still get alarm falses. I will be taking it back to the Car Toys this weekend to get that wire taken care of (insulated better).
On a related subject...I understand that the double beep is a fault. what can cause it? Every time I get out of the car and lock it I get the double beep.
Yea, I took it back today and they said the brown wire with the blue stripe is an audio input wire and is not certain which wire is the proper wire to isolate. So I am back to square one on the falsing issue
!
Anybody on which wire?
Any pictures of this wire? So I take it to these clowns and have them properly fix my falsing problem?
TIA.
If you press the arming button twice (rapidly), that arms the alarm but turns OFF the interior motion sensor. The car will immediately give you a quick chirp to alert you that the interior motion sensor has been disarmed but the car is alarm is armed. However, if you press the arming button once and then shortly after you get a chirp the alarm is telling you that it is armed but something is open or not properly closed. Usually it's the center armrest console microswitch, indicating it is not completely closed or the microswitch is bent.
Ah that solves it for me thanks to C four S and Function 12'' Thanks so much guys.. Mine only sounds on a double click so it is working as it should be... Thanks I am relieved about that. I will only click one time from now on.

From a Rennlist.org thread:
"I replaced my radio and now Ihave the problem with the alarm beeping when I lock the car. The car is a 2003 996 originally with the base sound system. I have looked at other posts on this problem which describe locating
brown with green stripe (or blue stripe) wire on the left side of the radio compartment
. I tried to locate this wire, but Icannot find it. I could not see any wires on theleft side except those that run to the PSM button and the wiper rheostat. Perhaps the alarm portion changed when theywent to the MOST bus system? "
"2003 and newer no brown/green wire. Radio is part of the MOST system."
"The durametric should be able to pinpoint the fault codes where the problem is sourcing from which could be ... (in no particular order, and not complete list)
alarm unit itself
fuel door flap
passenger comp. monitor
microswitches for doors
front hood latch
rear engine bay latch
radio ground
oddments tray switch
"other"
It's an exercise in futility and expensive if you try to "fix" all of the above possibilities without first knowing where the faults are coming from. "
Thanks. I'll have to investigate that center console switch.
Could it be related to a passenger window that is not dropping for door opening correctly?
Sorry for the hijack, I'll quit now
Not a problem... glad I could help. Just wish I can get a solution for mine now so I can get a complete nights sleep.
As for the the window not dropping causing the problem... not likely related- but hey with that said I have seen stranger things occur in these cars in my 10 years in them, so I would not be surprised if a case appeared here someday turning what I said on its side.
Looks like the key is having a Durametric, which the idiots at CarToys will not have. I hope you find the source, eidolon. Might have to bite the bullet and take it to a place that can properly diagnose it. Let us know how it turns out. I have been holding off on stereo on my 04 with NAV and got a quote from my local CarToys...
Will target suspension next instead.
Yeap, I agree I think having access to a Durametric is key... makes me wish I bought the one that was on sale here on the list a few weeks back. There was a guy at this Car Toys years ago that has worked on all my Porsches in the past... but he moved on and now I only have access to the generic everyday audio hacks and **** jockeys (I'm gonna wear that term out).
