hi again, so i decided to do a little job on the jag today. ever since buying the car its had an annoying msg on the display while driving informing me that the boot is open when it obviously isnt.

i decided that it must be the switch on the boot lid at fault so i removed the little plastic fir tree clips, and removed the 10mm bolt securing the panel and removed the panal.

on inspection there didnt look like there was anything wrong with the switch apart from it being a tiny bit loose in its metal bracket. but i decided to change it anyway since i had all ready bought a new one. i also discoverd that there was no bulb in the boot lamp so i put one in to see if it would light up and IT DIDNT.? 

anyway i dissmised this and moved onto the switch.

i fitted the new switch and thought i had better test it to make sure it cancels the warning msg on the dash.

and low and be hold the fault is still there. iam now wondering whether or not the bulb fault is related..

has anybody else had the problem. many thanks

 

Hi Simon,

 

You have tried everything, so I would guess that the message centre is thinking that because there is no reaction from the bulb in the boot when the boot is closed then the boot must still be open.

 

I know that sounds peculiar,  but sensors are not human!

 

Peter.

peter, i thought the same. i wonder if theres a dedicated fuse for the boot lamp. will have a look tomorrow. all the best bud

UPDATE: 

so, i decided to check the owners manual to see if there is a fuse for the boot lamp, found said fuse which is also for the interior courtesy/map lamps. these are still working so i would assume that the problem is located elsewhere. time to get my trusty power probe out i think.
