and your expecting a 2 ton truck to return decent mpg?
if you want decent mpg you'd be better off with a 200/300tdi

I think I get around 22-25mpg but not urban driving, I'm out in the country. Less when towing obviously.

I get way more than that, not worked it out for a long time but averge about 550-600 miles from a tank
I'd replace your maf with a genuine.
Do you have a heavy right foot? Because mine can get through a tank in no time if your a bit heavy on the accelerator

I'm getting about 22mpg, I suppose it would be 'urban' use, plus horse trailer most weekends.

The autobox TD5 in std trim is imo, much heavier on fuel than the manual version.
If you look at official mpg figures you'll see the combined figure for the auto is approx 26 whereas the same figure the manual box car is 30mpg but I reckon the difference is even greater.
With the autobox car in std trim the TC (torque converter) is not at all ideal and allows the engine to rev quite highly, like a manual box car with a slipping clutch.
With an Ashcrofts HD TC this tendency is much reduced and consequently mpg improves.
But before doing anything else, whenever I get another Disco the very first thing I do is to change all fluids and filters - to establish a baseline for future servicing.
The other thing worth checking is the condition of the MAP (Manifold Absolute Pressure) sensor on the inlet manifold. These are VERY often caked in a tar-like substance rendering their effective operation much reduced. Clean with aerosol brake and clutch cleaner.
Cheers

My TD5 auto does have the HD TC from ashcrofts fitted.Around town(very heavy traffic-20 minutes to do 2 miles)I average about 100 miles for 25lts of fuel,but on a run at motorway speed limit I get at least 150 miles per 25 lts of fuel.If i backed off to 55-60 where she seems to almost do no work I am sure the figures might be even better.
These figures are for bio though and may not translate to diesel exactly.

that sounds better biolandy, whats mileage on your truck regular service? and how much are the HD TC from ashcrofts?
going to blank egr off, decat pipe, clean map, replace maf, an possibly a map from td5 alive along with a full service an see how i go from there.
cheers

If you do go the re map route,google Dynachip,Mike knows his stuff regarding TD5 remaps.He will do this at your home/place of work.
Yup regular servicing,and I do drive it,love the acceleration-forgot to say it is also chipped by Mike at dynachip

Hi Sulli most D2 auto owners who have done the HD torque converter modification find that solves all the issues in one go.
Have a look here : Ashcroft Transmissions
Sadly it's not just a matter of plugging in a PC and playing with the transmission ECU.

Just back from a rundown to Blackpool on sunday, back tonight. 551 miles on 80 litres : 31.3mpg Mostly running at 65-70mph with self and 3 passengers. Pretty reasonable I think...

+++ the Light Foot.
I have had a leaking exhaust manifold gasket for a while, and keeping that quiet means I have been using a very light foot.
The MPGs improved considerably...
