My V12V engine cover sensor is playing up.

If I close the engine cover normally then the dashboard shows the alarm saying that the engine cover is open.
To stop the alarm I need to slam it with quite some force so that the rubber seals go above the lead, and I presume pressure it against some type of sensor or electrical contact.

Does anyone know how to solve this or disable the sensor ? For example is there a fuse i can pull out ?

Thanks !

I have a '13 V8V and have had the engine cover open message and auditory alarm for about 2 months now. I have found no fuse that works and I even took off the grille and unplugged the sensor and it still did not terminate it. I assume it is a bad sensor and am 4.5 hours from dealer so plan to get up there this month to have them repair/replace it. If you find anything that stops it please let me know! The auditory bong is maddening!

Well at least I can get it to shut up by slamming the bonnet closed !
Do you know where the sensor is located under the bonnet ?

It is underneath the mechanism the hood latches into and you can see it with a flashlight through the grill but have to remove the grill (which is quite easy to do) to get to it. I unplugged the electrical connector and it made no difference...

Try shorting the unplugged wire as the sensor probably creates the circuit rather than breaks it

How would one short it out? What damage could that cause?

just connect a wire between the 2 terminals, it shouldn't damage it as that is probably what the sensor does, it will just be a switch that creates a circuit when the engine cover is closed.
