<< Hello Michael

 I DO have the 1.8 switch, and I do have the intermittent buzzing and
 flashing, and the VW people I've talked to do say it shold be the 1.8
 switch.
 I do understand how the system works, but I want to be pretty sure that I
 don't do something stupid if I replace the 1.8 with a 0.9.

 Thank you for replying.

Hi again Johan,  the .9 switch belongs there, period!   Let's just say that
I'm wrong, even though that I'm not, if you put the .9 bar switch in place the
1.8 switch, you just fixed your intermittant problem, that is if you are low
on oil psi, wich you are not because obviosly you have somewhere around 1.8 to
2.0 bar of oil psi to keep the 1.8 bar switch CLOSED.  Let me know what
happens.  Tell your VW engineers to look a little harder in the factory repair
manual.   Michael Modl, 87 syncro.
