had the same problem with a 91 and an 84 jetta.  on the 84 jetta
replacing both oil pressure senders corrected the problem.  on the 91
it was a section of the computer system that was bad.  i wired to
individual oil pressure lights to the dash.  a green one for the lower
pump and a red one for the upper head located sender.  a lot cheaper
than trying to replaced the big chip behind the dash.
