in the past there was a compain from the dealer about bad head gasket they had to replace both head gaskets with updated gaskets does the engine run rough for a few sometime smooth out? if so the gaskets are blown you need updated gaskets.is there alot of steam coming from the exhaust? another sign of blown head gaskets. how many times do you need to fill the radiator? you can also pull spark plugs from each cylinder and find the cleanist plug in that cylinder thats also a sign of blown head gasket in the area of the cylinder head all fluid goes out the tail pipe thats why you have to fill the radiator
ask a question. White, blue, black? its most likely steam on this new of a car. nothing to worry about. if blue, its burning oil, blue on start up is leaky valve seals, black on startup is leaky injectors, real white smoke (tons will come out) not steam, is blown head gasket or cracked head/block
Is this the diesel model ? or petrol power? Never lug your diesel engine it will overheat even a new engine. Check your coolant level when engine is cooled down it may need burped. Why the head gasket change? did the head get checked for cracks and surface flatness, could be still leaking combustion pressure gases into the coolant have a test for this
