Old Mosher Posted July 16, 2017 Posted July 16, 2017 Hi.C5 2.0 Hdi 07. Overheating when standing in traffic. No cooling fan running! Had a quick prod around with a meter. All the fan power conecters are ok. Have power to the main conecters and across the relay switched terminals and an energising voltage across the relay coil. So I bridged the terminals to represent a closed relay, fan still didn't run. Have I missed a secondary contact somewhere or should the fan have run? Quote
Old Mosher Posted July 16, 2017 Author Posted July 16, 2017 P0495 fault ecu integral cooling function - coherence between fan speed and reference value. looking at it my fan has the integral motor controller, so I'm guessing it's duff. Ebay offer replacements for my C5 and pug 407 ranging from £60 used to £220 new. So is there anything going to be a problem fitting a used fan. like chassis no coded in etc and can anyone think of anything I should test first? Quote
