Hi, Can anyone help. I have a red light coming on ,, on the speedometer and a Message "Bonnet Open" I checked the bonnet and its fine. Does anyone know where I can find the bonnet switch / sensor so I can check it out.

 

The switch is part of the latch and is separately replaceable. Part C2D27159. Common failure item actually. I got mine from the dealer.

 

A paper clip in the connector of both of mine solved the issue for me.
The location is on the drivers side hood latch, an easy replacement, or bypass.

 

Thanks very much for the help. Cheers

 

Ah ha ! Beware ... Driver's side in the US (LHD) ... Passenger side in the UK !

 

 

In your case it'll be the switch as others have suggested. I kept getting the 'bonnet open' red light warning when driving along. When I inspected the bonnet it was actually open, only a little, but it was open. I released the bonnet and found that it would not shut without really slamming it down. When it eventually engaged it would ping slightly open again once I was driving. I greased up the latches and that solved the problem. The latches seem to seize up and will eventually start to release the bonnet when driving or going over bumps.

I hope you get it sorted.

Thanks,

Chris

 

The problem is supposed to be caused by oil from the lock mechanism working its way down into the innards of the switch and getting on the contacts. Jag's solution is, allegedly, 'don't oil the lock mechanism'

I shorted mine out with a bit of aluminium foil from a Kit-Kat bar.

 

Patrick the Cat,

Thank yes its on the Passenger side. Cheers

 

XJ350,

Thanks for the info, will make sure I grease it up when I change the switch / sensor.

Thanks

 

Spraying the contact points, with a contact type cleaner, might solve the issue.
Worth a try if you have a can setting around.
Many of us do for some reason.

 

Wingrider,

I removed and sprayed the contact points 2 days ago. And no more "Bonnet Open" warning Lights. Thanks for your help (All of you)

 

Glad you got it sorted Bruce
