On my Multivan when I got it, when I locked with the central locking the boot is unlocked and when I unlock it the boot locks.
Got it now so that when its unlocked the boot is unlocked but when the van is locked the boot can still be opened partially, although not fully open.
Tried reading the handboot but cant understand German!

The boot lock works off the key alone, and one key fits all locks.
Any help apprieciated.
Ta, Chris.
