Turbo is bad, when you start seeing black exhaust turbo has gone out completely. Depending on how old the turbo is and how hard it is driven, how many miles and so forth.

Misfiring cylinder 3 & 4


Sounds like a bad turbo to me. When you "kick it in", the engine falters and you get black smoke for a while. What is probably happening is that the turbo is leaking oil into the intake air stream, putting it into the cylinders with the fuel/air mix and causing one of two issues. Either the oil is inhibiting the combustion process, causing the falter and the resulting poor ignition, plus the oil, is giving black smoke, OR, the oil in the cylinders is fouling the plug momentarily, resulting in the fuel/oil being passed into the exhaust stream, burned in the catalytic converter and exits as black smoke. If it runs OK except when under turbo load, have that thing checked out ASAP. And, as far as the light staying on, most faults will set permanently after they occur three or more times within a certain period of time. This is ti ensure that intermittent faults won't cause false setting of the light.

Exhaust smoke definitely not steam. Someone opined that it may be related to the turbo/exhaust system. What do you think?


A worn turbo or broken would create smoke. Blue or Gray smoke is either worn rings or a clogged PCV. White smoke is from foreign fluid entering the engine. Typically indicative of a head gasket leak. Black smoke is Leaking injectors or an ignition problem or an issue with the turbo.
If you are experiencing a loss in power then you most likely have a worn turbo bearing.

Black smoke in the exhaust and in high rpm white on passat 1.9tdi


this case , you have to check turbo charger , when high RPM white smoke means lubricate oil goes to engine so give white smoke . on low rpm trubo close coming black smoke means no enough air gose to engine so this need to replace turbo . some type of turbo can be clean the wase gate ( which open with diafam beside turbo) make sure it's moving when accilerate. check vacum is ok . then clean wase gate > only some type have wings inside )if no replace turbo

Power loss, black smoke


Hi, the problem you are having is going to be with the turbo you will probably find one of the hoses going to the turbo has either come off or has a split in it.
It can be hard to find the split but this is the most likely cause of the problem.
As the car is losing power at high revs then this indicates that either the turbo itself has failed or it could just mean that their is a split in one of the hoses.

A split hose is the most likely cause you will need to inspect every part of all the hoses connected to the turbo. When these pipes get a split they dont then have the correct pressure for the turbo to work at best running conditions this is the smoke your seeing out the back.

a good way to check this is by the amount of oil in the car if your regular topping it up then this would mean looking deeper into the engine to find out why oil is getting into the cylinders but if you are not topping the oil up then this would mean their is no fault with the engine.

So have a good look around the turbo pipes give them a good squeeze the split might only tiny but that is all it takes to cause the problem your having.

If you are unsure at what to look for then its best left to a garage as they would have a good idea where the fault would most likely be.

Let me know if you need further assistance ok.

Power loss and black smoke?


I had a similar issue to this after I got in a VERY small fender bender (literally) in an 87 Turbo Supra. In my case, my pasenger fender got pushed in JUST enough to crack a charge pipe and cause a boost leak.

Basically, what was happening was the turbo would spool and build boost, the mass fair flow sensor would read all this air coming in and tell the ECU to dial up the the appropriate amount of fuel. When the air reached the cracks in the charge pipe, it would escape out of them. Thus there was a much lower air-to-fuel ratio, causing less fuel to combust, which lead to power loss and black smoke out of the exhaust.

My guess is either an oxygen sensor, or more likely a boost leak.

Good luck mate.

Sounds like you might have blown a ring on a piston. and the black smoke is oil being burned...find out what the engine code is....but a blown ring usually requires an engine rebuild to fix. Hope this helps.....sorry about the bad news

Black smoke from exhaust


This is almost certainly a split hose - mine was the large hose coming out of the bottom of the EGR valve.

Speaking to a parts guy at my local Jaguar dealer, he said that the new part is uprated as Jaguar are aware that this is a problem.

The split allows more air in and results in the ECU changing the mixture and over fuelling - Black smoke is an indication of un-burnt Diesel. As well as the black smoke you may also notice a whistle/whine or sucking noise when you accelerate and a lack of power / lumpiness at around 2000rpm.

Hope that helps!
