I installed the VW relay in the UBERWGN (1995.5 S6 Avant) and it works
as described.  I don't like it, because you can't change the variation
very easily. You have to turn it off and leave it off for a "long time"
maybe a minute" before it will reset so you can set a new interval.
Maybe I'll try the APS/Autotech unit next, if I can find out how to
order it...
