The engine is not overheating no leak of coolant however the fan is consatntly running fast when engine is on. Computer is showing 1 fault possibly with the air con.
I have had the coputer hooked up to a bosch diagnostic machine can find no fault anywhere else except one that says "warning coolant low visit workshop"
I think its an issue with the airconditioning but need help before I have to shell out a fortune.
