[Vwdiesel] Oil Pressure idiot light & buzzer

[William Longyard]

My buzzer and idiot light come on at about 25psi, which is way too high. 
I'm hoping the sender is bad, but I haven't had time to swap it out.  It is 
VERY annoying.  A Volvo engineer friend told me that you only need 10psi per 
1,000 revs (at the most).  So if you're idling at 800 rpm you only needs 
8lbs of oil pressure.  My 25 lbs is plenty.
