White or light grey smoke is unburnt diesel when the engien is cold. As the engine warms up the smoke will turn dark grey to black.

Another explanation for white smoke is antifreeze.

Does it smell like diesel or antifreeze?

Watch your antifreeze level. Take a quick look at the inside of the engine oil fill cap also. Should be just oil looking and not milky white.

I think it smells like antifreeze. When the engine is warm,still have white smoke. When front window is little open its smells too inside the car. When is closed not smells. Maybe after 60-70 km on motorway think the smoke is little bit, but in city drive is see at back.

Have you checked the coolant level?
Also look at the oil level fill cap.. underneath if you have a blown head gasket you will see white milky instead of just oil.

Everithing is normal with engine oil. Clean BLACK. Fill with little antifreez and will check daily.

There are only three places in the engine where it can burn coolant: headgasket, turbo and headgasket. Do a chemical test for combustion gases in your coolant reservoir.
