My oil temp and coolant temp gauges started shutting off and throwing codes. P3081, P0195 and a Check Engine. Sometimes, one or both of the gauges will come back "online" and all or some of the codes go away. When I plug in my Durametric (Enthusiast Version) and run the values scan with the engine running and up to temp, both oil and coolant temps show they are normal and reading fine. This leads me to believe that it is not a sensor issue but a connectivity issue between the OBC and the gauges or an issue with the gauges/cluster itself.

** If I clear the faults and restart, one or both of the gauges will come online for a while, then randomly shut down and throw a code, never at the same time though.

**. Oil and Engine Sensors show 2.8v 2.9v respectively with engine off and 1.11v and 1.074v while running.

I would really like this not to be a Cluster replacement fix! $6200 from Porsche just to get a new cluster from the Motherland!!!

That being said I would greatly appreciate any helpful/constructive advice on how best to proceed in troubleshooting / Diagnosing / and Resolving this issue


P.S. This is my first venture into a Forum for help, I apologize upfront for the lack of any and all Forum / Help skills on my part. Also, if anyone knows how to convert Iphone pics to the correct format to upload, I have several pics I could share if it would be of any assistance.

Cheers

 

Anyone know where I can have my instrument cluster rebuild/reprogrammed?

 

Second Update

I disconnected the battery terminal for 10 min, ran car for 10-15min and 2-3 miles. No codes and both oil and engine temp gauges worked just fine. Several hours later drove again but this time oil temp sensor fault code appeared almost immediately, which seems odd as the engine temp was not to even up to temp. The Oil temp gauge never moved over the course of my 10mile trip. Two hours later when I started the car I once again got the oil sensor fault on the dash and then a few moments later the Engine temp fault appeared and engine temp needle stayed at zero. Several minutes into my drive home, the engine temp needle popped up to 175 and the corresponding falult cleared. Oil temp never moved of of zero.
