2000 A4 Avant 1.8 T Sport Oil Pressure Sensor Failure
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?!?!?! |

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> |

Known for decades and not just in A4s, not just in 1.8s, not just in Audis. Why the Bavarians insist on specifying and using these pieces 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 a 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 ... -- C.R.

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? > IMHO, if nothing else, sometimes things happen.

Maybe I'll just buy a six-pack of sensors and change them whenever I'm bored. ;o) |

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. |
