I have imported a 1999 C2 Cab. (WP0CA2995XS650805) from to Norway from USA. My local Porsche dealer has changed speed display and AC to metric units (KM and Celcius), but they told me they where not able to change the outside temp display from Farenheit to Celcius.

The car doesn't have an On-board computer lever.

Can anybody here confirm that it's not possible to this change on my Porsche, or - if it is possible - tell me how I can do this change (so I can forward it to my local P-dealer)?

Thanks for all help

I don't think you can change the OBC display from F to C - there isn't an option to do that on the PST2. The OBC units are specific to the cluster for the country. You can change the digital speedometer and odometer from miles to kms yourself - it is explained in the manual. On early aircon panels you can also change from F to C yourself.
