Oil Pressure Problems .. please help
Out of no where, the oil pressure has decided to spike. The gauge is pegged at 80psi , and the reading on the DIC shows the pressure to be at 130psi.
But there are no "check gauges" light, nor is there any kind of warning on the DIC. Is it just the sending unit that has gone out, or might it be something else?
Also, where is the sending unit located, and how easy is it to get to, if that's the problem ?
This is happening on a 2002 A4 w/ 95k miles if that makes much difference. Thank you in advance guys.

Very common C5 problem.
your oil pressure sensor has failed...
It is a DIY fix. If you are patient and have fundamental tools.
here is a link to the fix

The key is not to over torque 15 ft-lbs
and to ensure the connector is free from all residual oil...

I cant believe gm made this engine making it this hard for a damn oil pressure sensor. The old gms it was in the engine block near the spark plugs and would take 3 mins and 1 wrench to remove. Now u have to take the damn engine apart just to replace a sensor? I am very close to selling my car for a porsche after reading this. It is almost like there is nothing to look forward to after your car goes over 50k except to drain your bank account! I bet you if you went to a dealer to do this your bill would be over $1000 for a stupid sensor

I guess you have to weigh the choices to decide what option is most appealing to you. I hope you stick with the vette!

Get familiar with the "Search" part of the forum. It'll save you a lot of time with things like the headlight problems you were having and the oil pressure problem probably has a hundred threads. Use it like an encyclopedia, it's faster than question and answer.

I don't think you'll find a Porsche any easier to work on. I don't know about their reliability either, but even more $$ to repair/replace parts too. From what I've read BMW's and other pricer cars all have their issues. Maybe less issues w/ a porsche but overall you'll pay more for the car and up keep anyway. I enjoy driving an american sports car and the LS1 platform is known for it's reliability. I do admit these issues you mentioned are annoying and the outsourcing of parts that become unreliable are a pain. For the major parts I enjoy upgrading to high performance ones and build my machine gradually. It's nice to have a great forum for advice and fixes/repair to help save some $$.

I also drove for almost 2 years with the bad sensor. Nothing bad happens but eventually the sensor will leak oil, which is what prompted me to finally get off my duff and fix it.

It's not that bad. My dealer quoted around $400 for the fix but I did it myself on a liesurely Saturday afternoon for the cost of the sensor - about $30. You just have to pull the intake manifold which seems daunting at first but once you've done it once it's easy.

......"nothing bad happens but eventually the sensor will leak oil". Wow, you mean you don't care to take an accurate oil pressure reading only once every two years?? Indeed, nothing bad MAY happen, unless your pump takes a..... but hey, you won't need a sensor by then to take an accurate oil pressure reading....just listen to the rockin'&knockin'....while it lasts, which may be long enough to get home!!! I would NEVER recommend to anyone that they ignore their oil pressure readings for two years, be they low or high. I will say, however, that it does make one wonder just how accurate a brand new sensor is, seeing as how so many members have had a failure (or two!), me included. It is a very sad statement on the current ways of the world when a major auto company puts out one of their top of the line cars, say a $50,000.00 car, and put such a cheap (Ten cent!?) sensor in charge of such an absolutely CRITICAL engine function. VERY SAD, indeed. :o

Replaced mine today. I did the cutout method and it wasn't to bad. The darn hoses are in the way. You just need to work around them. I used a rotozip to cutout the fiberglass and when done I put the cutout back with some aluminum tape on the back and black silicone caulking on top. Looks almost factory. I went to Autozone and picked up the sensor. It's made by Duralast and its American Made. Looks like the the GM aluminum replacment part. We'll see how long it lasts.

Once again, this forum has saved me from having a heart attack!
When I saw the oil pressure on the DIC, HUD and guage all pegged @ the max I was afraid to drive home - figured that there must be a plugged oil cooling line or something. What a relief it is to hear that this is just another one of those "quirks" like the crappy headlights and feeble trunk release, etc.

Mine too
My oil pressure pegged just the other day 130 PSI, I did the cut out method and it worked great you just have to be careful of the hoses back there and have a long handle priors and long screw driver to un-do the clip make sure you clean everything before you stick the new one in and tork it no more than 15 LBS and check for leaks before you put everything back took me 25 min.
I also had to use a dermal tool and I had to take the guard off so I could cut out the lower part and I could control the cut allot better than using a disk cutter.
