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.

I've got a Peugeot 407 HDi 2005 now with a power loss, particularly obvious in low rev range, blowing black smoke - looking like excessive fuel input. Also, it is using a huge amount of fuel.


Is it a diesel. If so it could be the particulate filter blocked, or it could be a failed fuel pump or something internal of the pump, or if a petrol it could be a failed catalytic converter, undo the exhaust and see if that changes, if so then look closely at your exhaust.

Twin turbo 80 horse power deutz Diesel engine blows black smoke under load


Diesel engines smoke when under a heavy load. Unlike a gas engines, a diesel engine uses fuel that is more like an oil.Smoking is a good indication the fuel is not completly burning because of loaded engine spee. White smoke indicates the fuel is not ignitingefficiently. Truck, boats, tanks abd anything else using diesel fuel will smoke when it gets more fuel than it can use.. Easing up on the throttle will lessen the smoke but not eliminate.. Of coarse if the demand is lessened by applying less loadyhe fuel consumption drops.Not to worry as long as the smoke doesn't attract the EPA.

Why want 6.0 blow black smoke with banks 6 gun iq


Black smoke from a diesel is caused by overfueling, even with a banks the engine obviously is burning the fuel efficiently. Black smoke will not make your truck produce more power, i am not sure why you would want this to happen anyway.

Peugeot 407 2.0 hdi lots of black smoke when you put your foot down past 2000 rpm


The reason for the black smoke is that it is not getting enough air to burn the fuel completely.It could be a blocked air filter,obstruction in the air intake system,blown turbo,hole in tube between intake manifold and turbo,or a fault with the fuel system and injectors.

Welcome to the world of diesels....

Black smoke is produced when too much fuel is injected into the cyl. There could be several issues here, but I would start with running a diagnostic on your O2 sensors and MAS/MAP sensors.

I hope this helps
