W202 False alarm...Help

[Single650]

On two consecutive nights the alarm has gone off spuriously...Just once.
To help me and my neighbours can anyone help with advice.

A. How can I turn off the alarm whilst leaving the car locked
B. What is likely to cause, a clue might be that I caught next door cat using the tyres as a scratching post this morning. Is the alarm that sensitive?
C. How can I change the sensitivity of the alarm sensors

Thanks

Nigel

A. You cannot turn the alarm off just the interior motion sensors via the button on the upper control panel.

B. Remove all cobwebs from inside the car. A star diag test will highlight what sensor triggered the alarm activation. The siren is common to fault and fill up with water.

C. You cant change them on your car.
