I have a 2010 Citroen C3 Picasso 1.4 petrol. A few months ago my car fan became very noisy after a long journey. Since then the car control panel is telling me the engine is overheating even if I have only just started it and the fan is going mad.
I took it to my mechanic who couldn't do anything because the message wouldn't show when I was at the garage. They sent me to an electrical mechanic who looked over the car and said the temperature sensor was showing at 240 degrees. I booked it in with my garage to replace. Unfortunately when I took it to the garage the message had disappeared and they said to leave it until it appears again.
My view is it is an electrical fault. What are your thoughts? Also every other day it struggles to start. It will start after a few pumps of the accelerator. On a long trip over the weekend I did a little test. If I am driving along at a steady pace and then (for example accelerate to over take) the warning light will appear telling me the engine is overheating. I had a look under the bonnet at our rest stop and the engine was as it should be, nothing to suggest overheating.
