Not familiar with that area / module but what I would do:
1. disconnect battery / fuse?
2. since you have the unit out, may be try to "clean" the "zebra" connector between the main board and the display? I would imagine the connection method is the same as CDR24

1. If the unit is out - nothing will be gained disconnecting the battery/fuse.. there is no power to the unit
2. Worth trying, but the coincidence of the display not being distorted or showing missing pixels - but showing what it is - which is the wrong items displayed after a diagnostics read was run on the car makes me think the display memory has somehow been corrupted. Luckily - if another "auto" unit from the same era can be sourced it probably can be swapped right over.

I would be interested in seeing what another diagnostics tool might make of the 5 errors being reported - something like a Foxwell.. or Durametric.

BTW - OP - Welcome to Planet-9, the Friendly Forum for Confused Porsche Owners!

It's sort of traditional here to introduce yourself over in the new member area, and post a few pics of your car. Good place to do a bit of reading on how to make technical request posts (your's is excellent BTW..) and some other forum specific stuff. You can find all that at: https://www.planet-9.com/forums/new_members/

Welcome once again!

BTW - I may decide to move this thread over to the Diagnostics forum we have - but that can wait until we see if any useful input arrives in the thread here..

 

I did the same thing and am having the same issue now. Anyone figure out a solution?

 

I went back and forth on this issue with both iCarsoft support and my local Porsche dealership. Neither were able to fix the existing unit. Porsche wanted >$1600 to replace the unit. I ended up buying a used one on ebay for a couple hundred. Swapping the unit out was the easiest repair I've done on this car. Took less than 20mins.
