Ok thanks, what if you have the get blanked off, it's common knowledge so it appears if the MAF is caked you lost performance

Lol,
The MAF sensor measures the amount of exhaust gas being ingested so that the ECU knows how much to modulate the EGR valve to control it. It unlike in a petrol engine has nothing at all to do with fuelling, that is controlled by engine power RPM request. Diesels are not throttled by air, but by fuel. So otherwise than when the EGR is active the ECU doesn't give a shit how much air is going through the MAF. At any given engine speed or manifold pressure there is always the same amount of combustible air in the cylinder. Excepting when EGR is active then part of that air not needed for the power level engine RPM requested, is replaced by exhaust gas to lower combustion temperature and reduce Nox production. But even then, fuel quantity for that given engine speed, manifold pressure, power demand, does not change.

It certainly isn't, tell him to look at the manifold pressure sensor, try flushing the intercooler if you haven't already done that.

Sorry to divert back to Engine performance but my TD5 seems to be much better sometimes than others, I have done some bits to it new air filter, injector seals, new fuel pressure regulator, new MAF sensor ( I mentioned it once but I think I got away with it) but one thing I notice is that the exhaust is very sooty, even after a 100 mile run, I don't get any noticeable smoke when running but inside the tail pipe is very sooty. I looked at a few newer defenders with the Puma engine and they seem to have lovely clean exhaust pipes, makes me fee mine is running rich. years ago I had a type 3 VW and if I did a long run the inside of the tail; pipe had a coating of white "ash" which made me thing it was running OK or maybe a bit lean.
Is this common to TD5s ?
By the way I tried millers and I thought it ran better, I also tried Shell super diesel ( or whatever they call it) and I am certain that it runs better and gives better MPG.

Just my tuppence. I got a 5L big tin of Millers from the Bay, saves a fortune on buying it in smaller bottles.
On the downside, easy to get greedy with a big tin, I add 40ML per 20L of fuel.
It makes a massive perceived difference to the smoothness and sense of greatly increased engine power.
Really would like to see it verified on a Rolling Road...
