while i was in the process of removing my mk3 gauge cluster, i figured i'd make a simple walkthru with pics in case someone didn't know how to.
you'll need a flat-head and phillips-head screwdriver.
gauge cluster before removal
pop off outer plastic cover next to headlight switch
stick your finger in here and press retractable button to remove headlight switch
where the button is located on switch
remove screw hidden behind headlight switch
pop off plastic cover (if you have heated seats, remove outer cover first to remove switch)
remove screw hidden behind cover (or switch)
the plastic bezel is held in by the 2 screws you just removed and clips up top
once bezel is out, remove one screw on each side of gauge cluster
cluster sits on 2 rubber grommets at the bottom. wiggle it to an angle to get it out. unplug the 2 connectors at the back of the cluster (3 if you have ABS)
wiggle some more and you're free!
hope this helps someone!
