Black Smoke from Exhaust and loss of power

HI Can anyone point out what could be the issue with my Disco3, only just recently I noticed that when I move off, there is a noticeable loss of power, but the car then does pick up speed but very slowly, and its just not responsive as it used to be. I have also noticed that there is a hell of a lot of black smoke coming from exhaust pipe. could this be Air Filter, maybe a service is required, or I am fearing something a lot more serious.

Search the forum for "Intercooler hose" and "Black smoke" - that will give you something to read.

If you can't find a split in any of the intercooler hoses you will need to get the codes read.

If buying a new hose, or set, I suggest you go for silicone not Bog standard JLR.

If no split in the hoses, mainly the big one look for an oil patch on the inter cooler itself as that may be split or burst. Thumbs Up

It will when others won't,
It goes where others don't.

 Land Rovers don't leak they just mark there spot
1973 Land Rover Series 3 110 safari Gone but not forgotten
1990 Discovery 200Tdi Gone thank god
1996 Discovery 300Tdi sadly missed (still going strong but not with me)
2003 Discovery TD5 Gone to LR heaven
2004 Discovery TD5 Gone to Aberdeen hope it likes it there
2005 RRS HSE Rimini Red (my Disco 3 in a posh frock)
Think I see a pattern here
