What is often called "Vanagon Syndrome" (AFM wiper surface wear) applies
to 1.9 and 2.1 engines.  VW initially identified the problem as
affecting 2.1 engines and came out with a "Harness fix".  They later
revised that to include the 1.9s as well.  BTW that harness fix works on
both engine sizes also.

One fix is to remove the Phillips head screws (a bear) and to move the
board a tiny bit (may have to elongate the holes the screws pass
through).  that way the wiper has a fresh surface to ride on.

FWIW, both my AFMs are performing well and don't have the harness or
capacitor fixes ... though I do have a suitable capacitor at the ready
... and a Phillips screwdriver.  ;)
