VW needed a convenient way to make the OXS (or EGR for the early folks)
light come on as a bulb check and then go off when the engine is started
and remain off until the service mileage interval had passed.  I guess
they figured they could wire it in with the alternator light so that
when the alternator light turned off when the engine was started, the
OXS light would too.

The downside is that if there is a charging system problem, both lights
will illuminate.

Of course if the mileage counter triggers the OXS light, only the OXS
light will illuminate.
