I don't recall "details" about the rear hatch of an avant, but isn't 
there a key-activated lock mechanism, like the sedan trunk lid, (in 
which case it should be openable with a full twist of the key)?

As to repair: Again, assuming that the central-locking pneumatic 
mechanism is similar to the sedan's, the failure you encountered is 
usually caused by a jamming of the small ball-bearing (in the 
assembly containing the lock cylinder). This tiny steel ball can be 
removed by prying or popping it free (see Chris Miller's website), 
and this will will restore operation of the central locking. Of 
course it's also possible that the pressure tubing has simply become 
disconnected from the rear mechanism.


P.S. Of course I have no direct experience with an avant, so for all 
I know the central locking depends on the labors of a small colony of 
gerbils who live inside the doors. Notice any unpleasant odors coming 
from the doors lately? :-)
