Sounds like it's overfuelling, fuel quality shouldn't be do bad as to make things that bad.
Unless it's been tuned? Run some Diesel additive though to see if a boosted octane rating will help. The injectors are very sensitive and newly fitted ones need programming. Also the injector seals can have issues. |

Thanks for the information I've done the additive and no change.
It was the same old injectors when back in. It will work right I know it some day. |

Black smoke is normally over fuelling OR restricted airflow, given what you have done I would suggest changing air filter and checking turbo actuator

Could there be any obstruction in the air intake system? Maybe an object or foreign body got in or accidentally left?

I have a similar problem with my defender. It's a 59 plate 90 xs 2.4.
When I start it cold, the amount of smoke that comes out is terrible, and driving it leaves a bit long cloud of white smoke until it warms up, then it disappears. When I put it under heavy acceleration when cold the smoke changes to a darker colour, and when warm, it's clear u top heavy acceleration, and then the usual rich mix smoke. I have changed the air filter last week, and it's a straight standard 2.4 no mods. The turbo seems to be working perfectly, lots of power. Does anyone else have anything similar? 64000 miles on the clock. Cheers |

Yep, true that. I made the mistake of using diesel from my local village gas station which in a very short time ruined my injector pump. It was only then that it was suggested by the repairer that I should only fuel up on the main highways (in my case the 7) because unless the holding tanks are regularly filled and emptied, they get contaminated with water. Never did manage to get the engine running nicely after the injector pump rebuild and left the country shortly after. |

I add 2 stroke to my TD5 and my VW T5, I did quite a bit of reading up on it beforehand though as I didn't want to have to repair / replace 2 engines

Sounds to me lke it is generally down on power. 100-120 kmh flat or downhill, is slow, if you mean flat out.
Fuel shouldn´t make that much difference, but there are a number of other possibilities. As mentioned, the purely mechanical aspects need to be checked. Obstruction in the air intake, blocked injector. it would only take one to cause a sizeable drop in power, and the other cylinders over fuel trying to compensate.. Too much oil in the sump (a recent oil change maybe?). Partially blocked catalysator. As it is a 2.4, you don´t have the DPF to blame. Did the problem start directly after the service work? Good luck. Don´t lose faith in the girl. 1998 Tdi 90 SW, 2008 Td4 90 SW, 2012 2.2 90 SW, 2" raised Trailmaster/Terrafirma Heavy Track Raids, 255 MT´s, Recaro CS´s, anorak, wellingtons |
