Alan, based in Lancaster, UK. The information here is really useful, thank you to all those who have put it here.
I have a Hymer B544 motorhome based on a Fiat Ducato chassis, 2016. We've done around 50k miles and am having a problem because the external temperature display has been crazy, reading up to 86°C but seems to have failed completely now, showing ----°C. I can't find the sensor, found some really helpful stuff here and working on the problem.
In the past I have sorted out problems with the Truma heater and 12v not powering the fridge and added fans to boost fridge performance, if any of that's of interest to anyone I can post details although this might not be the most appropriate place as they are not really Fiat things.
