Hi all,
I retrofitted one of the later square BMW volumetric alarm sensor units (the one that is located near the center of the headlining) but I can't get it to actually work. I followed this guide here and is definitely wired up correctly:

When I lock the car I can hear the alarm sensor making clicking sounds similar to rear parking sensors, but no matter how long I wait after locking the car (should start working after 20 seconds) the sensor isn't setting off the alarm when I'm moving about inside the car.
I have 2 sensor units and have tried both in case one was faulty. I have the exact same problem when I tested one on my typhoon years ago.
Does the volumetric alarm need activating on a t4? I can't see any option to activate it on toaf.
Cheers
Rick
