BMW E46 3 Series DIY

After speaking with a tech at the dealership. They confirm that this will only work with vehicles ARE programed to flash. It usually cost about $60 to have them do it.

My vehicle is already programmed to flash the lights and the clown nose. If yours isn’t programmed it can be done at the dealer.

List:

T-30 torx
Electronic buzzer- Radio Shack 90dB Piezo Pulse Model: 273-060

Time: 45 minutes easy DIY

Step one:

Remove the twist clips holding down the cover to the cabin air filter. Remove cover and filter.

Step two:
Remove (4) T-30 torx screws holding the filter tray and carefully separate the wire harness from the loom.

Step three:
Remove (2) torx screws holding the protective cover for the blend air box. There is one to the left side by the A/c charging port and the other by the DME.

Step four:
Locate pre-wired alarm siren plug. Usually taped to the left side.

Step five
Locate Black wire w/ Blue stripe far left, bottom hole.
Then locate Brown wire w/ Black stripe left upper hole.

Step six:
Pin the ground wire into the lower left hole.
Pin the positive wire into the upper left hole.


~~~ Test your key.
CAR SHOULD BEEP TWICE TO UNLOCK.
(NOTE) YOU MUST HOLD DOWN THE HOOD TRIGGER TO HEAR IT BEEP ONCE AND LOCK!

Step seven:
After deciding where you want to mount your buzzer mount it down with double-sided tape this is where I mounted mine.
** Switch for a bigger buzzer so that the sound is louder***

Step eight:
Put everything back together and enjoy.
if you got any questions please feel free to ask.
Thanks
