Just wanted to highlight something that had me flummoxed for nearly three weeks. Basically, I couldn't open the boot from the driver door button or the button under the boot lid. The only way to open was via the key fob. So after checking the fuses (which were all ok), I discovered an "On/Off" switch located in the glove box on the right. It was in the "Off" position. I flicked in on, and presto, the boot opens from the lid and the driver door button. I guess somewhere along the line I have inadvertently tripped the switch (which I didnt even know was there till today) - so if anyone else has this issue, its likely to be that switch and NOT a fault - therefore its always worth checking that before anything else.
