Re: Oil Warning light(HELP US BOTH)

[Greg Faust <FAUSTGE@BUFFALOSTATE.EDU>]

If you're having problems like these with your oil pressure warning light,
follow the very simple and very easy test procedure in the Bentley.  Or if
youre lazy, just replace the pressure switches.  They about $10 each from the
dealer.  Yes, from the dealer.  Thats probably the least expensive part they
carry.  The PL (16v) engine has two switches on the filter mount, one normally
open, one normally closed. (the temp sender is on the head).  It takes about 30
seconds to change and is by no means worth a trip to the shop.  I had to
replace one on my s2 because it leaked and buzzed as you describe and I just
changed both on my 84 GTi( one was leaking, and the other switched on at any
rpm over 2k)

good luck and happy motoring
