Default Car Alarm, anti-theft.

Since I would like to remove this car alarm just because it annoyes me seeing every day!
I'm advised that the wires from the sensors inside the car will be wired up with the ignition key's wires.

Yesterday we couldn't see what car alarm I've got fitted. Well me personally I wouldn't have the faintest clue anyways.

It was suggested to me it can be Scorpio or Gemini.

Who knows?




And BTW now that you're reading this thread: the cable to the inside door handle on driving side snapped when I tried to get out of my car at work today! Is it dead easy to fix? What do I need to buy?

Door handle - u should buy + screwdriver to remove that door handle, and, in worst case trim panel as well After that u will see what had happened with that cable and do u need new one. That was one of first my A80 problems, which I fixed - actually I regretted after that that I bought new cable - price was ~12 pounds in local parts store. Because in junkyard that would be much cheaper.
Alarm - go ahead. Stock alarms are useless anyway. Does engine with disconnected control unit works?
B3, from which I got almost all wiring harness for my A80, was equipped with alarm, but without it, there was no problem at all. As far as I know, B3/C3/D11 stock alarms was for sound only, no "immobilisation". Dunno about newer audis.

I think it's disconnected now and was when I bought the car, so yes, the engine works.
The only problem should be IF the old wires are connected to the ignition key or not? For THAT reason it is worth it finding out what brand the alarm is, I am told!

Great! Sounds easy! And good advice to see what's broken or missing before I rush to Halfrauds.

Unfortunately alarm installers compete on time-to-fit and thus take the same shortcuts every time.

If you remove the plastic covers surrounding the top of the steering column so you can see the wiring behind the ignition switch, you will usually find a wire cut and spliced within an inch or two of the switch - typically on Audis it's a yellow wire that powers the X circuit.

On most immobilisers two such wires will be cut and connected to the immobiliser unit - unimaginatively the other one will usually be the starter motor solenoid circuit.

Such systems are only rarely removed - usually there's a key on the unit that disables it. Most people lose this key.

I've taken more alarms out than I care to remember - including my own, under a huge light in Heathrow Airport Long Term car park with no one so much as asking me the time of day.

That's a very useful explanation, thanks! Will print it and take it with me tomorrow. So I take it I can just go ahead then?

Oh dear! So either you look like a thug and they were too freightened to approach you OR you look like the AA-man and they thought you knew what you were doing?

Not sure of the procedure for removing the alarm. The door lock cable procedure is outlined at Section 11 of Haynes Manual 1491. I have had this same problem and found that the loosening of the allen screws inside the drivers door arm rest was a real pita and you will need to be carefull when removing the door panel so as not to break the plastic clips on the back. I have some photos that might help, will post them later.
