Next morning the car engine does not start. The battery is fine, but it seems that it does not get any fuel. Must be the cold, at night it was -20 C. Since I do not need the car, I just leave it parked.
A few days later I tell my hosts in the Albergo, they call the car repair shop, and the Fiat Doblo is being picked up and taken into the garage down in the valley.
Next day it is ready. This is the very first time that I go down a slope by skis to pick up a car from a garage...
There had been ice and dirt in the fuel filter, which then prevented the fuel to come to the engine. Is now fixed.
