Thread: I've got the TD5 black smoke / no power blues !!

Have done a search on this site? Lots of info that will match your symptoms. Clean sensors (MAP, IAP etc), connectors, check hoses(intercooler, boost modulator etc), intercooler for oil. On the full site there are two search options. One provided by the forum software, the other is down the bottom.

If the harness from the head is full of oil,then that is the first place to start.Renew it is the best policy Land Rover Discovery 2 Defender TD5 Injector Loom O E AMR6103 NOT Chinese Copy | eBay and then clean out the red plug into the ECU[located on rear of battery box]allow the plug to drain for as long as possible.Until both plugs are free of oil you are pushing the proverbial..then move onto checking for delaminated hoses......

With the thick black smoke occurring so suddenly then being OK I suggest that you inspect the intercooler hose between the turbo and the I/C for delamination from the inside, specifically the hose at the I/C (top left side of engine bay). This particular hose is prone to delaminating whereby a flap of inner hose temporarily blocks the airflow then resumes its normal position as soon as the engine stops. Blown turbo seals would cause blue smoke whereas improperly burnt diesel produces black smoke.

I agree with the eddy and Graeme. I've replaced my inter cooler hoses with:

They are not just silicon lined, the are made from silicon. People speculated they were only silicon lined because of the price, and I cannot blame them, but i have bought them and they are fine.

I have also fitted this exact loom eddy posted:

from "Roverlord" it is better constructed than the factory one I removed. Also as you are new to the forum and I assume Land Rover spare parts, Roverlord are great, they only sell quality parts and are almost always cheaper than any competitor.

I would say these two items, much cheaper than a turbo, will fix your problem. Both can be installed by anyone, definitely not a mechanic only job. I understand not affording to guess and throw money around, I'd bet the problem is your injector loom and even if it isn't, you need one anyway from what you've described.

Thanks Eddie, Graeme & Jazzman,
It's reassuring to feel I'm on the right track and that I may be able to fix it myself.
Thank you for the links. I will follow them up. Having the confidence to try these things is half the battle I think, and you have just increased my confidence.
I will post pics as I go of me pulling my hair out, no doubt !!
Cheers for now.

Good luck.

I tried the most simple things first. Bought a silicon hose kit and replaced the hoses from the turbo, the 2 small ones on either end of the metal tube.
The first from the turbo was fine but replaced anyway. The 2nd one was completely cactus! From the outside it looked and felt OK but when removed you can see the inner skin has come away from the outer at both ends which must have effectively been like a balloon in a drainpipe.
Having found that and replaced it I took it for a drive and it's been magic.
No problems at all.
I did buy an injector loom but see no need to replace it at the moment as there is no oil at the red connector end of the computer. So I have a spare if I need one.
I also still have the biggest of the new silicone hoses which goes to the intercooler I think, but was too cramped to replace in the time I had available.
So I'd just like to say thanks for the advice, it saved me from buying a new turbo and dealing with mechanics who 'allege' to know what they are talking about at your expense.
So 'thanks' and have a Happy Christmas.
