Thanks. Actually I drove to Sweden (Arvidsjaur) for a meeting late last week, and thats when my problems began. I went from +5 here on the coast of Norway to -10 on the Swedish taiga and back without any problems. Next morning the car started to play games, starting with DSC alarms before it now presents the complete range of warnings and takes the mentioned precautions.
I really hope you are right about reading the computer log, but I'm worrying that all this crap also are being registred as realities by the computer.
In case I hope a reset will do the trick. Anyway I'll report the result when its ready.
