AFAIK, the only pressure regulating device in the cooling system is the
expansion tank cap.  Could it be holding too much pressure?  When my old
pickup (1953 Chevy) has similar problems, I just loosen the cap and run with
no pressure until it gets fixed.  This may not be a great idea in the
Wasserboxer, but it works great in old iron!  Check the cap.
