300tdi Black smoke and lack of power !!!

(1/3) > >>

tomkbucks:
this is not happening all the time but every now and again i get a loss of power around 2k rpm and black smoke :( i thought there maybe a blockage or something so have taken off the intercooler, and pipes cleaned all that out it was black and thick of oil, engine has done 160k so thought it may help , its running smoother but after another 10k miles or so it developed the lack of power and black smoke under heavy revs. It seems to clear after a while, ive no idea what to do next, some fuel treatment ? new fuel filter ? ive checked the 2 turbo pipes when i took them off and cleaned them and they both have no splits , help !

KingWolf:
My 300TDI used to do the same thing, used to get really sluggish and start chucking black smoke out of the back, usually around 50mph in 4th gear.... I blanked off the EGR valve and it cured to problem for me....ran a lot better after doing this so it might be worth giving it a try if you've not already done so.

well drove in to work today and all seemed fine... so its not all the time ! its been suggested i try changing the lift pump, but im not sure as its not allways smoking and lacking power,

KingWolf:
strange that it's not doing it all the time, but my money is on the EGR valve if it's not already been blocked off. I've just changed my lift pump as it's been a bit week ever since I brought the Disco and would really struggle to reach the higher revs from 3rd gear upwards. However this was not the cause of my smoking troubles, but then again no two engines are exactly the same.....

Hi mate

Check your intercooler pipes, it sounds like they may be compressing when the turbo kicks in.
