I have never seen a VW diesel with a tachometer.  The "W" connector is
(was) used to run the Dynamic Oil Pressure System on my '89 Jetta diesel.

Subject:    Re: Alternator with "W" connector

This "w" terminal is used in diesel models, as a signal for the tachometer.
With out this signal you need to provide a signal from a distributor
to run the tach., whitch diesels obviously don't have.
