It does nothing under normal operation.  It's supposed to be
connected to a 3 (?) pin plug mounted to the alternator, so that some
esoteric piece of VW gear can be plugged in and detect TDC with
it.  It's a coil with an iron core, generates a little pulse when a
magnet goes whizzing past it.  Presumably there's a little magnet
buried in the flywheel at the appropriate place.  In regular
operation it's as useful as the proverbial appendages on a boar hog,
or those tiny ice cube trays in the Westy fridge, i.e. not.
