<< I've been driving my '85 Golf for years with the same whacky oil
 light/buzzer problem. Usually occurs when I just start out the driveway. A
 good rap on top of the dash shuts it up for a while, sometimes weeks.
 Whatever it is, it isn't the oil!

Frank,

        I had the same problem with my 85 Jetta.....only happened at 2250 rpm.  I had
a VW tech tell me there was a problem with the instrument cluster for that
year...some sort of bad component....he recommeded retrofit with a later
module cluster.  Time to hunt those junk yards, eh?  Also, don't be using
those FRAM filters, dude...
