[Vwdiesel] Oil Pressure idiot light & buzzer

[LBaird119 at aol.com]

  Degraded performance from low oil pressure is only during that 
few minutes, when the pistons or bearings are expanding from 
heat, and right before they gall and seize!  :-o
  Yes, you need to put a gauge on the engine, check your pressure 
cold.  Warm it up and check it hot.  Check idle and at ~2000rpm.
Your pressure could be low, a sender could be bad, or the warning 
unit in the speedo could be bad however it seems like most of those 
"failures" from the past COULD be misdiagnosis.
  Low oil pressure is most likely from failing intermediate shaft 
bearings.  Engine has to come out to replace.  A worn or spun 
rod or main bearing could do it if it's been neglected along the 
line.
  Sending or control units would have to be replaced.  Since the 
buzzer does sound, the W terminal wire seems to be working (for 
rpm signal.)
