Audi A3 Alarm Siren Mod
I have been looking for one of these sirens since reading about some members on tdiclub.com who put them in their cars. I combed ebay.de for a few weeks since a new one from the dealer goes for $270Cdn, plus the casing, and the plug which drive this to over $300 for an alarm siren.
I finally found a seller on ebay.de who was willing to ship to Canada, and who also accepted paypal which made for a quick transaction. In order to keep the cost down, I bought 10 sirens with wiring plugs. Unfortunately the breaker cut the harnesses very close to the plug on most of the harnesses, so it looks like repair wires will be needed to splice the signal, power and ground to the siren.
These are Bosch sirens, 9 have part # 1K0 951 605A and one has part # 1K0 951 605C. These have built in NiMh battery backup, hopefully there is some juice left in these batteries as they come from used cars in Germany.
The metal casing is also an OEM piece and the part # is 1K0 951 227. It's a heavy duty bracket and appears to be made of stainless steel.
The wiring harness connector has part # 1J0 973 703 and the 90 degree cap on the harness has part # 030 971 921.
So the sirens I got were for the MK5 cars, I got the proper MK4 sirens - part # 1J0 951 605A Works like a charm and sounds great compared to the old duck honk alarm horn.
