I have an intermittent problem with my seat leon 2.0 tsfi 190 the temperature on the dash takes a long time to get up to the right level but then goes 1 light beyond normal it never goes higher than that but when i turn the car off the radiator fan is running full speed for a minute but then slows to normal for a bit before stopping, i never get steam or coolant loss but it does trigger the the engine check light when i looked this up before I found a thread that recommended checking and cleaning the electrical connectors to the cooling system but this has not cured it any ideas please
