Loss of power and black smoke

Recommended Posts

Hi I have a 1998 300tdi 110, and the engine has started to loose power intermitently, and emit thick black smoke.

This typically occurs once I have slowed down to go round a corner.

Stopping the engine and restarting seems to get the vehicle back to normal.

Vehivle has over 400,000 KM on engine, so is a bit worn.

Thinking it may be the turbo - any ideas? 

thanks

Has it ever had the injectors replaced or serviced?

400,000 KM on one of these engines is nothing. They have a design life of over 400,000 miles. 

I had over 300,000 miles on mine and apart from a head gasket failure at 212,000 miles, a couple of P gaskets and a couple of inlet manifold gaskets, no problems at all.

have a good look at your air induction hoses, could have disintegrated inside, and a piece is flapping about blocking air intake. ( turbo to inlet manifold). It's fairly common.

The EGR valve sticking can also cause problems, I am lead to believe.

I had a similar problem with the intercooler hose collapsing under load and starving the turbo of air.  I replaced it with a silicone one and no issues since.

Gents, Thanks for all the advice, I pulled off the 90 degree elbow between the turbo and the intercooler inlet pipe and found the hose to have collapsed inside , causing a large balloon which blocked all air flow.

I'll post a photo soon.  The exterior of the hose looked fine

Thanks V much, engine pulling great now I have replaced this hose.

This is a view of the turbocharger to intercooler hose, very hard to see any defect from the outside. The inside was completely blocked.  Worth checking if you have a 300TDI
