cockBought my 300tdi in 2007, the boot never opened unless you opened it from the inside using the handle and pulling up the lock thing, key didn't work so I assumed the lock was ronnied.
Anyway, I was moving house and went through all my keys and found the spare set the guy had given me, one had 'D' marked on it.
D is for door, and I can now open my boot from the outside... after 4 years of looking like a complete **** climbing through the back to open the door in shop car parks.
