Since we bought our ducato (used) the outside temp has remained at 0" A quick look up told me the sensor is in the o/s mirror, on checking it was not ,must have had a mirror change. Being to tight to buy a new mirror I bought a thermistor off ebay £2.80 wired it into the mirror arm, drilled a little hole in the plastic and it all works.
Ps checked the n/s mirror found that had also been changed and new one had no radio aerial so that is the next job.
