The alarm on my Fabia went off twice last night, seems to be a false alarm and it's never happened before.

Thing is, the last couple of days when I got into the car there was a spiders web between the door and the steering wheel.

Is a spider marching across the sensor enough to trigger the alarm, or is that just silly?

 

this happened to us a few weeks ago sometimes it can be change in weather pressure especially if you leave vents open, none the less the wife had me do a full bug sweep on the car... not happened since
