The car shown in the instruction video is either not an EX30 or a very early model, as my boot light is smaller, fitted higher in the side wall....
and impossible to remove. One reviewer said it could be pushed out from the rear by reaching under the plastic shroud...well you can feel the back but
it feels as if the rear dimensions of the fitting are bigger than the hole and so there is no chance of being pushed out. The video makes it look like a 5-minute job
but unless I can gather more courage to risk breaking either the shroud, fitting or wiring, it's going in the bin....drat I hate PCP deals for this very reason.
I don't suppose anyone braver than me has actually managed to remove their boot light fitting, and if so, how...please

For interest, here is the instruction video.
