Black exhaust = Rich mixture.
Check air intake for dirty filter or restrictions
Black Diesel fuel= Waste oil added to fuel
Find a different fuel source, or check for oil being drawn into the fuel system
Hey you bought tata 407 turbo and they smokes black and performance is poor i think you need some service for your turbo 407.

Best I can tell this is a diesel truck? I know diesel, but
depending on age could be injectors, possibly Diesel injection pump hopefully not. The fuel is black? Someone is putting old engine lubricating oil in the fuel tank. It will increase the problem of black smoke. It may also have a bad smell because of the engine oil. If the turbo is not spinning properly (high pitched whine) the bearings may be bad and it's not getting enough air into the engine. This would also explain the smoke problem. Take it to a Diesel specialist!

hi did you check the turbo,s housing where the turbine is for oil or signs of sooty deposits and when you had the hose off did you check the turbo,s intake pipes for blockages and check the air cleaner as well does the turbo make any wirring noises and is it petrol or diesel paul

Blace smoke is fuel to much of it are you talking about the vaccume line thea goes from the turbo to a tee then the wast gate and a sensor under the air box thenthen up to the bottom of the air box?

Remove and clean the EGR valve.If that doent work replace the airflow meter.

Hi, I have a 2.0HDI Expert which was doing the exact same thing as yours, blowing thick black smoke, sluggish and loss of power on gradients, a hissing sound and surging. I replaced the air flow meter but that didn't help. I was told to replace the turbo but a turbo expoert told me not to as it would blow white smoke if it was faulty. I was then told to replace the injectors but a diagnostic test showed them to be functioning fine. I was then told to look at the intercooler which had thick sludge at the lower left pipe. I replaced it today - Sunday 12th July and it is now driving like a new van. It now pulls me up gradients with ease in 4th and 5th instead of having to drop gear to get to the top. I got a replacement from Euro Car Parts for £147 inc VAT. To tell if this is your problem, look through the gaps in the lower section of the bumper at what looks like the radiator and look for sludge over the inside of the bumper and all over the pipe where it joins the back of the radiator (intercooler). Also open the bonnet and look down behind the grille for the same sludge. Hope this sorts it for you. Barry, Newtownards, Northern Ireland.

Black smoke = excess fuel. Could be o2 sensor, blocked fuel pressure regulator etc... should have vehicle scaned they may be able to extract a code, if not a fuel pressure test would be good to
