I've just bought a 2nd hand B-Max (2015). The alarm keeps going off and the 'Bonnet open' alert appears on the display window. The bonnet isn't open but the car's obviously confused. I took it to a couple of garages and looks like I need to buy a new bonnet lock/latch for at least £200
I just wondered if anyone else had had a similar experience and could shed light on any options I might have? I've never had a car with an alarm before and would be happy not to have it, but apparently it's not possible to disable the alarm. The car is now parked on the street outside my house and the alarm keeps going off intermittently at seemingly random moments, it's driving me insane.
Thanks in advance for any advice
it is possible to put the alarm into a lower 'detection' state, so it doesn't detect animals / abandoned children in the car...
but given you get bonnet open messages, I would suspect the bonnet switch. I think its a seperate switch from the catch assembly, but can't check at the moment.
I would expect it to be the switch on the latch. They do unhook from the latch. There is a plunger that detects the claw status. You can use a dummy striker to view if the plunger is being operated correctly.
ok I checked, and there is a microswitch mounted on the lower latch assembly. then there is a connector.
I think if you unplug this connection, you should be able to test it.
or botch it with a paperclip to connect the 2 wires. - but this must then be insulated and secured somewhere.
