It does it with the a/c switched off. The engine light has not been on, I am not getting any fault codes. I have checked the fan control unit is ok, the ECU is commanding the fan to run [disconnecting the purple wire stops it] The a/c has been re-gassed to correct quantity and I have replaced the ECT sensor - neither had any effect. On live data the ECT, IAT,MAP and MAF all seem ok, the car runs fine and mpg is fine. I don't know what is causing it to want the fan to run. I appreciate any help or advise with this.
