Indeed it is in the locking mechanism. There's mention of it in the Bentley manual. Anyhow the reason I ask is because with the boot light connected, I get a flat battery in a couple of days. I'm 100% sure that the light is going off with the boot closed (back seats down and check) but I was wondering whether a dodgy switch could cause a current leak.
A friend has the same problem - has anyone had similar?
