Aircon fan on full time usually means an overheating issue. Mine was a faulty sensor.
You say no fault codes, did you get the engine temp from the ECU? What was that reading? It wasn't me! |

I had similar - the AC fan cuts in when the engine overheats/coolant low. I had similar symptoms on a V8 - the coolant level had dropped a bit low. JB

Even when turning the engine on from a cold start, the fan comes on. It's daintily not an overheating issue.

Does the ECU know its not overheating? Mine had no faults stored, ran constantly from cold and ran normally after the sensor swap. It wasn't me!

It is my understanding that the A/C fan on the Td5cuts in at 28 degrees ambient temperature I think it gets its reading from the sensor in the air filter box, could this be faulty ? Could be worth unplugging it and seeing what happens. 2005 Td5 90 XS

I had exactly the same problem. Had the air con re-gassed (even though it was running very cold) and that fixed it.
