I too battle smoke. 2003 td5manual. No cat or egr. torque remap, bigger intercooler, CRH lightened standard turbo.
If there is a little 1.8 sign on the bonnet-slam, then the emissions have to be below. If not then 3 is the limit. I'm told that they have been known to fall off as the glue is not too strong!
On mine, a blast of brake cleaner into the MAP sensor cleaned it up significantly. I've replaced it since, with a new Bosch unit, but not a huge further improvement to be honest.
I had to replace my turbo recently as the bearings were shot, which also helped. It might be worth giving the spindle a wiggle.
Make sure it is really hot when it gets tested and it might also be worth removing the air filter cartridge for the MOT to increase the air flow slightly.
Since I did these jobs, the idle is much cleaner & it only visibly smokes under hard acceleration.
I believe the MOT test is meant to be at full revs and constant speed. Some testers possibly have a little more mechanical sympathy than others & maybe don't rev so hard!
Mine just got under the "3" at the last MOT. Good luck!

I'm not a troll either but I do keep seeing Ad's for a fuel additive that allegedly works wonders.
They have been advertising in Classic Car Weekly for a few years and the results appear positive.
Also seen this 'Stop Smoke Oil' ? Also in CCW
I would like to see an independent review of any of these additives or oils before I splashed out.

That one could definitely mix up the emmisions a bit on Eu3 engine but you should have noticed some power issues too unless this one was not genuine LR. Drive with it unplugged cos it's better than with a dead one, the only one which would work well is the frigging expensive genuine LR, all the rest are complete lottery, depends on your luck but there are many cases when it's better without it than with aftermarkets
Gotta disagree with you there.
The car was far from perfect but the TD5 gave no trouble. Powerful enough for me, great for towing and reasonably economical.

Plenty not to like....
Wet loom,fuel economy,heavy services, expensive insurance.....the list is long.
There's a reason the MOD regected the td5 powered defender....

I've ran 2 in a disco and defender. Brilliant engines
I can compare it to owning or running bmw m57 and n57, audi 2.0 tdi and 3.0 tdi, nissan 2.5 dci, ford/psa 2.7 tdv6 so I'm not exactly an uber td5 fanboy.
Tuneable and long lived, bit ****y with fuel system and yeah the looms an arse but its not hard or expensive to fix, no harder than many many other engines
Great land rover engine

There is a far more simple reason why the MOD rejected the TD5. It was simply because the TD5 is electronics heavy.
"The British M.O.D. did not decide against the Td5 in it's army vehicles because of unreliability, it opted for the 300Tdi because it deemed it's electrics were more easily managed in the field. As stated, Td5 electrics are extremely reliable, and a range of plug-in diagnostic management tools are available to the civilian owner. Hawkeye, Nanocom etc. Regardless, life without a diagnostic tool is not difficult."
So nothing to do with your list.

Wouldn't need plugging in if it was designed properly in the first place
Land rovers stopped being produced in 1998.....
EDC came out in 95/96 on the tdi autos, so if you want to avoid engine ecus you need to be prior to that, or stick to manual gearboxes.Wouldn't need plugging in if it was designed properly in the first place

I had a td5 for 5 years and 50k, it was okay, flat as a fart off boost, always an issue of some sort, even tuned it was nowt special.
I did check the mot status recently, and it currently has 190k on the clock and is still road legal.
Rare old bird, TD5 ES Premium in blue with piped cream leather seats with rear a/c.

I think you must have had a bad 'un, or I got a good 'un ?
Wet loom was a daft idea, but cheap and easy to keep on top of. For the size of vehicle and what it was capable of I was more than happy with the fuel Economy, Average 27Mpg. Over 30 on a run. The day after we bought it we set off on a family holiday. From Motorways to Green Lanes 1200 miles averaging 33 MPG. Servicing no more expensive than any other car. And insurance was very reasonable. Over my 17 years of ownership insurance varied between £250 and £320, not the worst.
And what's not to like ? The water leaks into the cabin !

Not a bad engine by any means, no power house in stock form but better than LR diesels of old.
Reliability not too bad at all mine shat it's flexplate at 204k, engine still sweet as a nut had the typical oily loom and slight manifold leak but nowt serious..
But in typical LR fashion the body is rotting off the engine LOL
I might fix it, one day...
Maybe..
