Thread: Alarm going off- bonnet switch?

So my question is where is the bonnet switch located and how can you deactivate the alarm side of it ?

I’m trying to help him sort it from a distance as the car is along way from me.

Thanks in advance

Bonnet switch is on passenger side along side of the airbox. I doubt it is the issue but you can unplug it. It is more likely that the volumetric sensor in the cabin is being triggered by a moth or wind. When you park and lock the car make sure the windows are up. The volumetric sensor can be disabled if you have access to a Hawkeye or a Nanocom diagnostic tool.

Make suse all the doors are fully shut, particularly the tailgate. My tailgate can appear closed while not allowing various electrical functions to operate. A good slam fixes all issues.
