hello
I left the house to go to work in the morning and went to my car, I started the car because all the windows were frozen, I ran the front and rear window solvers and got out of the car for about 5 minutes. I looked at the exhaust, the black smoke threw disaster and it was dark, and what happened to the asphalt was as if the institution threw it was black on the asphalt, why would it happen? What should I do? 4 lira worth 4 different flights, 2 from the best side, 2 side oil office
vehicle 2003 307 1.4 hdi

black smoke means my rich wife. If it is cold, I would like to have the turbo checked, or the strongest result should be connected to the machine for the service.

Could it be about the injector?

It may emit black smoke at first start-up in winter and even at idle in cold. The vehicle makes a rich mixture. Check after warming up. Also, do not put gas on your car idle, never do it when it's cold.

Since the engine is cold, the electronic control unit makes the air fuel mixture using more fuel so that the engine idle speed does not drop. this is a rich blend. the poor mixture means more air and less fuel.

If you have maintained the vehicle's winter filter and oil very recently, if the oil rate is above max, the engine and gaskets etc. are intact, it burns excess oil, it is discharged from the exhaust as black smoke. br>
