LRNZ Posted March 31, 2017 Share Posted March 31, 2017 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 Quote Link to comment Share on other sites More sharing options...
neil110 Posted March 31, 2017 Share Posted March 31, 2017 (edited) 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.

Yostumpy Posted March 31, 2017 Share Posted March 31, 2017 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. Quote Link to comment Share on other sites More sharing options...
GBMUD Posted April 1, 2017 Share Posted April 1, 2017 The EGR valve sticking can also cause problems, I am lead to believe. Chris Quote Link to comment Share on other sites More sharing options...
ZIKOMO Posted April 1, 2017 Share Posted April 1, 2017 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. Quote Link to comment Share on other sites More sharing options...
LRNZ Posted April 2, 2017 Author Share Posted April 2, 2017 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. 1 Quote Link to comment Share on other sites More sharing options...
LRNZ Posted April 8, 2017 Author Share Posted April 8, 2017 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 2 Quote Link to comment Share on other sites More sharing options...
