So I assume you've had the oil pressure verified with a mechanical gauge
when cold and hot? You may not want to rely upon the fact that the engine
has not yet experienced an oil-starvation failure just yet, if your oil
pickup is clogged it will still run with low pressure for some period of
time, with accelerated wear due to low pressure. These engines have such a
small sump due to their marginal design that they now require a strict oil
change interval of 5000 miles with a larger filter (to get the oil capacity
up to more than 4 quarts) and a VW/Audi-approved synthetic oil (in the US
the most common of these oils are Mobil1 0w40 and Castrol Syntec and
Valvoline Synpower 5w40).
Unless you say for certain that your motor has adhered to these requirements
since new you have a possibility of having an oil starvation problem due to
oil coking. And unless you can prove to Audi you've adhered to their
oil/filter/change schedule, you'll be SOL on any warranty coverage.

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???

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???
