Anyone know anything about this?

We had a sensor failure (or blockage?) back in May or something at which
point the sensor was replaced, and it looks like it's happened again. Got
the critical warning about oil pressure, but oil pressure IS good (or else
the engine would have died a thousand deaths by now...) Only happened after
driving 20 miles or so at 80mph.

It's a cheap part to replace, but is this a known issue or have I been
singled out by some sort of evil conspiracy, or perhaps even ALIENS?!?!?!

experience. Might want to have the pan dropped and check pump inlet screen
and pickup tube for clogging.

IMHO, if nothing else, sometimes things happen. I've replaced five
thermostats on my H1 Hummer, but no one says its a known issue! <bg>
However, once you get to five, then you can say (as I do) "It's a know
issue!" <rbg>

of crap for such an important function I can't imagine. One good thing
about them is what you mentioned: they're cheap. Two other good things
about them are:

1) You can buy 'em almost anywhere - I get mine at AutoZone.
2) They're really easy to replace on the BMW M30 3.5 head ...

That's cheered me up quite a bit - thanks!

Thanks, I've heard of that, but, as I said, the engine is fine despite
running it afterwards (after having the AA guy checking that oil is still
moving around) so I really don't think this is the issue - it had a complete
oil change just a few months back anyway, with the correct fancy silicon or
whatever oil.

Tin??? You mean this baking-paper-bonnet I'm wearing is insufficient
protection? Where can I get this "tin-foil" as you call it?

Hehehe, well, it's becoming an issue known to me, that much is true. Maybe
I'll just buy a six-pack of sensors and change them whenever I'm bored.

;o)

Oops, terminology mismatch! Yes, the baking-paper-bonnet is fine,
sufficient.


I'm not sure I'd recommend that, but if you can get them from a couple
of different makers you may find one make is better than another...

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.
