  I agree with David.  I bet you have low oil pressure.  Marginal.   So when
it is fresh and cool, the oil light and buzzer *just* stay off...just
barely.  When it warms up, the oil pressure declines, causing the 'dummy
lights' and warnings to 'go off'....

   If that were my van, I'd be looking for another $300 inline VW motor
(just to have, in case)  ...Since it's a WBX motor...and you seem to be
unconvinced that maybe you have a problem...get thee an oil pressure gauge
and see what you actually got going inside.....Or maybe do The Ostrich and
wish the buzzer and the oil warning don't ever go off again...I hope it is
all good for you....
