 I'm trying to find out which switch I should have in my engine.
 You seemed to be pretty confidant in your reply to Anthont Kimmons, that it
 should be the 0.9 bar switch. I have the 1.8 bar switch, and my local
 VW-mech says that is the one. But my german repair manual says 0.9, and so
 do some people on the list.
 I have the 2.1 l 112hp DJ engine. It's european only, I think.

 What do you say? >>
Hi Johan, you have the .9 oil psi switch by the crank pulley. If you use the
1.8 psi switch, you might have an intermittant oil light coming on while
driving, at 2000 RPM or higher. Since the oil psi on these motors at 2000 RPM
is around 1.8 bar, this may cause the oil light and buzzer to come on. The 1.8
switch is used on the Golfs and Jettas.   Remember, the control unit in the
instrument cluster does not ever want to see the .9 switch OPEN at 2000 RPM or
higher, ( the .9 bar switch closes from oil pressure between .8 to 1.0 bar ),
do you see now how the 1.8 bar switch can screw thing up.  Good luck, Michael
