BMW X3 boot won't open

I own a 2011 BMW X3. The car has developed a fault, which means I can't always open the boot. It can take several presses of the key fob to get it to release. What is the cause and is it a known problem?

The cause is moisture getting into the rear lock servo and the reason is the vast amount of water and much that gets flung against the back of a hatchbacked car as it drives along. Try removing the trim panel and squirting the lock servo with WD40 ('Water Dispersant 40').
