Hi guys,
I have a vw sharan tdi if I drive it locale its fine but if I take a motorway for about 40min to 1hour drive the temperature goes over 90d and refill coolant sign comes on. Every time I stop to check and always the coolant fluid is emptied from the tank. I don’t really know what cause this, I took the car to deferent mechanic but no one seems to know the exact problem. They changed all this parts, water pump, thermostat, rad sencer, tank and cup, radiator. There is no sign of blow head gasket as they said no babbles no creamy oil and no leak. Could anyone please help?
Many thanks
