Dollars to donuts you have the incorrect oil pressure sender for the >2000
RPM range.  It's the one by the water pump and belts, and should be grey
(.75-1.05 bar).  You probably have the blue one, which is roughly twice the
pressure rating.  You can probably see it with a mirror, but if not, may
have to remove it.  I will have an article on the Volks Cafe site later this
week which includes, among other things, instructions for getting to this
switch without too much headache.
