Another one of those common failures, motor turn but hatch remains closed,
there is some adjustment in the system but even at the max settings the hatch
remained firmly shut.
Motor adjusts by releasing and moving the two 10mm bolts.
Lock adjust by loosening and moving the 6mm Allen bolts
Here you can see the pivot that releases the hatch
Evidently you can get fatigue failure here if you release
mechanism is too tight. I had no such problems.
Picture shows what the motor does to the latch mechanism.
This is the latch after a thorough cleaning, full of gunk
To make up for the lack of adjustment make a small shim for
a suitable material, motor oil containers as suggested by someone else
work remarkably well.
Place shim at rear of lock, adjust motor to its least
aggressive setting and move until hatch releases, I still needed the motor
at virtually it's maximum setting so my system must be pretty worn.
While you are playing with the hatch it is useful to have a
helper to actuate the release button :-)
