Question Does the factory alarm have ..

Hi all

On a 2003 156 does the factory alarm have a shock sensor , there is not one in the alarm unit so wondered if there is one fitted else where on the car.

Thx

Mine goes off if you tilt it but bumps don't seem to do anything. Think it's in the middle interior light cluster but couldn't be sure as it hasn't broken yet. Not helpful sorry but gives you a bump.

Alfa 156

You are correct about the 156 having a tilt sensor, but it doesn't have "shock" sensors, it uses Volumetric Sensors in behind the centre pillar trim.

Basically the sensor measures the change of the volume of air (pressure) within the cabin. When that changes, such as the breaking of the window or a door forced open, it triggers the alarm.

This is done so that if the car is bumped, leant on, the bloody cat jumps on it, it doesn't go off every 5 seconds waking the whole neighbourhood up at 2.00am, but will go off if someone actually is trying to force their way into the car.
