| The oil pressure switches on US VW GTIs (Mk I) had a habit of going bad. I had
mine replaced when the car was about 3 months old.
An easy solution is to replace the eletrical oil pressure guage with a
mechanical one and disconnect the warning light. Of course, depending on
the age of the vehicle, you may not to do this. An it helps to have a full
time co-driver to keep an eye on the pressure guage - but since this is
my rally car, I have that one covered.
Another thing to look at is the locations of the sensors. They usually
pick them up on the side of the head or down by the oil filter. Can you
swap locations of the sensors? Maybe there is plenty of pressure down
low, but not enough up at the head.

| Don't suppose it could be a wiring fault ... the clutch pedal chaffing on
the wire from the sensor (you mention that depressing the clutch makes
it go away) ???

| 1644.3 | Mmmmmmmmmmmm - could be ! | NEWOA::CROME_A | | Tue Jan 07 1992 12:43 | 11 |
| I reckon .2 is on the right track, maybe a wire is earthing out behind
the dashboard somewhere. Try following the throttle cable route and
inspect the wiring loom at any points where the two might meet, also as
the wiring goes through the bulkhead. The rubber seal may have worn on
one edge allowing the loom to occasionally short out.
If your car does have two sensors and one of them is on the head, I
would keep a close eye on the camshaft, any oil starvation will need to
be spotted early to prevent serious damage.

| 1644.4 | VW oil pressure problem? | HEWIE::CHRIS | My plant, Eric, OD'd on Grendel and Baby Bio | Thu Jan 09 1992 14:09 | 15 |

I've just got a similar problem on my VW Santana, the head gasket went
just before Christmas and all the problems that brings. The things
been re-bored and all that, new oil pump fitted, and various other new
things, and has been getting run-in for the past few days. It's done
about fifty miles so far and apparently no problems apart from the oil
light coming on "when cornering & slowing down?". I don't actually
know what's happening, 'cos I haven't had access to the car, but that
was the quote from someone who's been checking the car out for me...
Any ideas please?!
Chris.

| Chris,
That's usually a symptom of low oil level. The oil "washes" around in
the sump, and the pickup can be left dry for a moment. Watch this,
it'll kill your engine. If it didn't happen before, it shouldn't happen
again.
Racing and high-perfomance cars usually have baffles fitted to the sump
to stop this, and oil surge.
If this isn't the problem, then it's time to worry. It could be a
blocked oilway or something.

I think the oil level is OK...one thing that comes to mind is that when
I fetched the oil pump it wasn't exactly the same one as the one that
came off. There was a small bracket that wasn't on the other one,
maybe that's getting in the way of a feed to/from the sump? After
driving about for a bit wouldn't the engine have seized up by now if
that was the case?! 'Scuse me if I'm asking daft questions, but cars
aren't exactly at the top of my knowledge list!

| No, it takes a long time for an engine to seize like that. It's not
being starved of oil after all. The reason you should look into it, is
that if there are new parts in there, they'll be tight, and will need
lubrication more than later. Somewhere, the pressure is dropping. It
could be the pump, but I still favour loss of pick-up.

Yeah, I think a restricted pick-up is the problem.
Ta for the help.

I borrowed a new Audi 100 VR6, and it did this to. Seeing it belonged
to Audi, I just kept driving it, and it eventually went out. No probs
with the oil, it was just screwed electronics. Me Audi Coupe S2 had
the same problem with the water light. Turns out it was a bad
"capacitor" in the electronics. The sensor was ok

| That's why I like mechanical guages. Even if the light messes up, you can
double check the real situation with a quick glance at the guage.

The Santana is kicking oil out like hell now, so the next stop for it
is the motor auctions after I've traded it in for something else.

| In case any of you are still reading this note (highly unlikely), I've
found out the cure of the dodgy lights on the dash board. Get the whole
dam thing rewired for 100 quid and you won't have any more probs. My
audi coupe gt5s has been Peeing me off with flashing brake lights, oil
lights, indicators not working fog lamps fusing. But not any more. This
dam car is playing a game with me but it's not going to win. Wot with,
Sub-frames snapping, head gaskets blowing, piston rings flying around,
exhaust systems being left on the M4.
Good Luck
