How did my snipping a part of your post alter the sense of what you said
and how I responded? You're saying that a pressure sensor will likely
fail before an oil pump will. And I'm saying that an oil pump may fail
and the pressure sensor is just letting you know that. Here. Two
different ideas. I don't have to agree with yours, and you don't have
to agree with mine.
Cheers,

Re: '98 A4 2.8 - Oil light
First off-- Thanks to Tony, Ronny, Pete, Mike & Daytripper for your
thoughts and comments.
My mechanic has had a bad couple weeks-- and I made the mistake of
saying-- "We're in no rush." Well, I wasn't-- but I forgot this my
son's toy & I was just dropping it off while he was working to pay for
it.<g>
Changed oil, filter & sensor. It delayed the light for a bit the
first day, but then it responded just as before. [light on when engine
reaches temp-- then on and off randomly, no change regardless of
rpms.]
So last night he put his digital oil pressure guage on it [in the same
hole where the sensor was] and told us to take it for a ride.
While sitting at the garage, cold idle was 30+ psi, pressure at
2000rpm was about 40.
Once warm, the pressure at idle drops to 6psi, sitting at 2000rpm it
hovers in the low 20s.
Out on the highway, holding steady at 2000rpm the pressure went from
20-27 for the first 5-6 miles, then evened off a bit to 22-25. It
stayed there for 20 minutes or so-- and went back to 6psi at idle on
the offramp.
My mechanic [not an Audi man, but a guy I've trusted for 20 years with
my cars] can't find anything but the 29psi at 2000rpm for oil
pressure specs. I've ordered the Bently manual but if someone has
some more datapoints, I'd appreciate it. [What pressure should trigger
the light? How bad does the oil pressure sound?]
Mechanic is leary of this and thinks it sounds more like a "tired
motor" than an oil pump/clogged screen problem. Any thoughts?

Thanks for that link-- lots of good reading. [But I didn't see
anything on 'what your oil pressure *should* be'. If you think it's
there I'll go back and try a little harder.]

We got the Audi filter-- but I talked to the other mechanic- who
actually changed the oil, and he used 10w-30 -- he's replacing that
with 10w-40 today.

I think I'll run the 10w-40 [Pennzoil?]- for a week or so, let it pick
up whatever gunk it can- then replace it with the Mobil One.
Thanks again to all--

Both the Bentley manual and Haynes give only the 29 psi (or 2 bar) at 2000
RPM minimum spec for oil pressure when oil is at 80C on the 30V 2.8.
