Wath do that mean when your car over heat an smoke comes in the car when it do over heat

What color smoke white means coolant. Blue means oil. You could have loss of compression causing the drag the noise could be a air or coolant leak

White smoke usually means coolant getting into engine and burning. The smoke will find the easiest place to come out. The reason it happens after heat is turned on is the coolant is active more

Is it coming from your exhaust. Does it smell like antifreeze? antifreeze has a sweet smell. That could mean a bad head gasket. Since it goes away after 15km, I'm assuming the heat expansion on the engine does away with the leak. It could also mean a lot of other things. Has your engine overheated recently?

White smoke means water is getting into the engine from teh coolant system. Likely that your engine cylinder head has a crack, or head gasket is bad

You mean from the aircon vent.Your cooling unit need a good chemical wash.Ice is forming in the cooling unit, the air outside is hot thus is the cold air forming smoke from contacting the hot air.

More details needed - from wath pipe?

Have it checked at your local garage. White smoke from the exhaust system.....normally means a cracked cylinder head gasket. I would check the oil dipstick to ensure that there is no coolant in the oil pan. Coolant in the oil pan could mean a cracked cylinder head......a more costly repair.

blue smoke = burning oil

however, your symptoms sound more like black smoke which means you are running rich.... this could be caused by leaking injectors

personally it sounds like you have multiple unrelated concerns... which do you want to address first

white smoke means water or antifreeze. blue smoke means oil. black smoke means rich fuel mixture. So if it is white you are burning antifreeze which usually means you have a bad head gasket or intake manifold gasket. is your car over heating? that is the main symptom of a bad head gasket. how much white smoke are you getting if it is not much it could be just condensation and nothing to worry about.

It means that the pre heat is in operation.It is a system that burns diesel to create heat to warm up engine quicker so that warm air comes into car sooner.The smoke is the exhaust gasses from the system and normally the whistleing and smoke stops when engine reaches running temperature or on short journeys approx 1 minute after engine is turned off
During summer when no heat is required and air con is on cooling it should not light even when starting from cold

hope this helps
