To get over the interior light not coming on, you need to hold the button in for about 5 seconds until the light flashes a few times. Release the button and then all should be well when opening the doors.The interior lights do not swich on if i open the doors. Even the one in the boot does not switch on. I found no way to switch it on, so i think it is a failure
[Credit to R1 on that one I believe]
I also had the problem of the boot light not coming on, that was a fault but got sorted whilst I waited at the dealership.
