'06 C70 frequent false alarm

The alarm can be triggered by vibration from outside: passing (loudish) motorbike or lorry, etc.

Sometimes it just goes off for no apparent reason: I understand from other posts that this can be due to a duff siren battery et., however, I want to concentrate on its being over-sensitive for now...

No dangling wires etc. in the passenger compartment.

If I could find the ultrasonic (I assume) transmitter or receiver, I'd try covering either with some light material to try and mute the sensitivity.

Any bright ideas?
