I recently purchased a used PCM 3.1 and it’s matching MFD / Cluster from a 2014 981 Cayman S… which is exactly the same model I own. And, referencing this awesome thread I was able to install everything successfully and get it fully functional, including the MAP and NAV functions in the MFD / Cluster.
I purchased a full set of codes for $150- from a well known business on Facebook, and had no problems activating everything using my PIWIS II Tester.
But now for the issues I need help with!!
1. I installed the PCM first, updated VIN and confirmed everything worked after applying the codes. I then installed the new MFD / Cluster and it immediately came up with the NAV and MAP menus and graphics… so I decided I should update its VIN too. However as soon as I updated the VIN the NAV and MAP functions / menus disappeared, and I cannot find any way to get them back. Does anyone know how to do this?
Someone suggested in an earlier thread that a code is needed… but for what, and where does it go? I cannot find any related ‘Function Enable’ line in PIWIS.
2. The PCM originally showed Cayman S in its start-up splash screen, but now defaults to ‘GT3’. This despite the PCM coding in PIWIS clearly showing Cayman S. Anyone have suggestions on how to fix this?
3. The new MFD / Cluster obviously shows a different mileage from mine, so I need to correct it. PIWIS does not offer this capability in either ‘After Sales’ or ‘Engineering’ mode, other than for a brand new unit with less than 100km on the clock… so I need to find some way to change it. Has anyone done this before, and can recommend a tool?
Would very much appreciate your suggestions.
