The car has done over 4,000 miles (it's now at just over 50k miles) since
the first oil-pressure warning incident (when the sensor was replaced) - are
you saying the engine could have survived that long whilst oil-starved?
Also, with the new sensor, there was no warning, so do I assume that the
first sensor was NOT faulty and that the new one IS? ;o)
It's been serviced by Audi whenever required by them, but if you look at my
subject line, you'll see it's out of warrantee now anyway...
And are you seriously saying it needs a complete oil-change every 5,000
miles???

When these engines "sludge", they do not lose all oil flow-- it is reduced
to some marginal level for some period of time, which causes insufficient
lubrication and increased wear. The engine runs, but the bearings
experience increased wear (VW checks the cam bearings for wear for this
problem, and replaces the entire engine if wear is out of spec). Given the
known problems with this engine, it is unwise to keep driving them for any
length of time when you get a low pressure warning without pulling the pan
and checking for "turbo turds" (hard coked bits of oil) in the oil screen
and pickup tube. Given your mileage (and possibly your service history)
your motor is a prime candidate for this problem.

If you get an oil-starvation failure you may need a new engine. Because of
this problem, VW/Audi extended the drivetrain warranty against sluding,
provided the owner has proof of proper oil changes. Even today, some
VW/Audi dealers continue to use the wrong filter and oil in these engines.

Yes, that is what is required, along with a larger filter (increasing oil
capacity by about 0.5 quarts) and the use of synthetic oil meeting VW/Audi
502 specs. This was outlined in TSB in 2004--check with your dealer's
service department about this. I know the relevant VW TSBs are 17-04-01 and
17-04-02. (engine oil warning) and engine oil and filter specs.

Yes.
It's not out of warranty for the Sludge issue. (Warranty was extended for
this)
See my story at
http://members.***.net/ambox/audi_sludge/
Of special note is that the Audi dealer claimed a faulty sensor for mine
(they screwed around with me replacing the LEVEL sensor even though it was
the pressure warning that lit).
The pressure warning will light when the pressure gets bellow 20psi at
speed. That's enough pressure for the car to run for a long time. Changing
the oil may restore some oil pressure by removing some large particles that
are temporarily blocking the oil pump suction screen, giving you some
reprieve.
GET THE PRESSURE CHECKED
First, you yourself can simply look in your oil filler cap and see how
things look.
Hope it's not sludge

Yes.
It's not out of warranty for the Sludge issue. (Warranty was extended for
this)
See my story at
http://members.***.net/ambox/audi_sludge/
Of special note is that the Audi dealer claimed a faulty sensor for mine
(they screwed around with me replacing the LEVEL sensor even though it was
the pressure warning that lit).
The pressure warning will light when the pressure gets bellow 20psi at
speed. That's enough pressure for the car to run for a long time. Changing
the oil may restore some oil pressure by removing some large particles that
are temporarily blocking the oil pump suction screen, giving you some
reprieve.
GET THE PRESSURE CHECKED
First, you yourself can simply look in your oil filler cap and see how
things look.
Hope it's not sludge
