Hi all I have this fault with my car that when I have the car running on data on my snap on solus ultra the car air temp and engine temp both reach 100 degrees the engine goes into anti pollution drops cylinder 3 and code p1339 Comes up , the fan brings temp down and if I switch off engine leave for 30 seconds switch on its OK again. I have recently changed plugs ,coil packs, thermostat housing, thermostat sensor, oil pump solenoid valve as these were other fault codes I had on the reader these are now all gone except p1339 which comes back once temp is reached, could anyone advise my next step as I think I need to get peugeot to set temp settings down to cut fan in earlier or something any help would be appreciated..
