Thanks, deckman!

Hopefully that's it and not the gauge, requiring a new instrument cluster like EB847 wrote about ...

remove and clean the electrical connections to the sending unit and see if that solves your problem. That worked for me. Put some dielectric grease on the connectors to keep them clean and prevent future corrosion from developing. I'd bet that a lot of failed sending units were just bad electrical connections.

I tried that first and would also recommend it. It didn't work for me but will for some others.

will this work on a 996 turbo? I have a 2001 that is getting the electronic failure. Dealer wants 600 to replace. I usually don't work on the Porsche myself. I have built many other motors but for some reason I have not messed with the 996. So if its this simple I may just do it but want to make sure that its the same on the turbo. Thanks.

For the last 2 days my oil pressure gauge has been intermittent... It's gone from a normal reading to pegging at the top of the gauge (above 5 bar), then dropping back down to normal at idle.

I'll call my buddies at Suncoast tomorrow!

If anyone can let me know if its the same process on the Turbo that would be great. I plan on doing this soon as I find the service manual on line for the porsche. My issue is when I do the electronic check it says failure so can't read the oil level. NO issue with the oil pressure so its an electronic issue. any help would be really appreciated..

Van

Andru, there is a different sensor for oil level... that might be what's bad on your car.

Ah, where was this thread when I had mine towed for the same issue while it was CPO. The stealership nimrods couldn't figure it out any better than they did anything else on the car. Mine still acts up every once in awhile. Bookmarked for my next maintenance week vacation!

I finally got around to changing that sending unit. It was a piece of cake!! It took more time to drive the car on and off the lift than it took to change it.

Step 1: reach hand in and unplug wires
Step 2: raise car
Step 3: with a 19mm crows foot wrench and a wobble extension, loosen sender
Step 4: lower car
Step 5: reach in and unscrew/remove sender
Step 6: drink beer and congratulate yourself for being half done
Step 7: reach in with new sender in your hand and screw it in
Step 8: raise car
Step 9: tighten new sender with 19mm crows foot wrench on a wobble extension
Step 10: lower car
Step 11: connect wires (luckily they are different size plugs!)
Step 12: drink more beer and congratulate yourself on a job well done!

Only a 2 beer job...nice.

I am doing thsi job in the next week as the failure signals are getting too frequent and I am getting bored of them. For the record can guys confirm that there is no danger to anything if the unit fails altogether except an inability to monitor pressure remotely?

Van

100% correct.

I have the same symptom happen on my Targa, the oil pressure stays in maximum level and all the sudden it will drop to 0 with failure indicator code show on dash display. I just ordered the oil pressure sender today and expecting to be arrive before end of this week.

I wonder how do you know which wire goes to which plug?

The 2 plugs are different size in my 996TT.

Bozbomber

Really? I pulled mine few weeks ago to clean it hoping to make the issue go away and remember it both plugs are the same size...
