Whilst you're at it, I would give the fuel sedimenter a good cleaning. It is located under the rear right hand side of the car, just in front of the fuel tank - is metal, and looks similar to the fuel filter sort of. It will have a screw-in plug in the bottom of it, just undo it and diesel should flow out (into a big cup or something - ~ 300mL will come out I guess) then undo the bolt on top of it all that holds it in place, and it will all come off. The main body of it is in two parts and will come apart after the bolt has been undone - IIRC there is a rubber seal between it which can be reused if in good nick.

Give it a good scrub and clean and dry thoroughly. Don't be surprised if there is a fair bit of gunk in it (mine was full of green mouldy stuff). Refitting is just the reverse.

One other thing I'd check is the turbo hoses to the intercooler, when I bought my Tdi it was a bit of a slug, and I found the inside of the 90º elbow to be delaminated inside, replaced and turbo spools up a little earlier and drives a bit nicer - they can look fine from the outside.

Other than that just check all the other fluids, if they look dirty, replace them. If you don't know how long its been since they've all been done, its cheap insurance to replace them all for the longterm I reckon.

Have fun!

Don't touch the Plastic plug on the bottem, 9 times out of 10 they will break.

Just un-do the nut on top and take the body of, with out draining it.

Actually, hook has a god point there... Last time i did one I broke it - its still well and truly stuck in the hole now. Just means you might spill a little diesel as you take the whole thing off as it'll be full.

If she is blowing a lot of black smoke, I would try running an injector cleaner through it, everyone has their favourite, I personally use fuel doctor and have had brilliant results with it to the point I have run it in my Ranger since new. But look in to it your self and use what you feel comfortable with.

Ahh, I have just been in the same boat, a newbie with a TD5 in a disco!

I was pretty happy with the service history when we go our (Disco 2) and so only changed the Engine oil at the time. Here is what I ahve found :-

Engine oil - there is a lot, make sure you have a big enough contianer - I didn't! its pretty easy to drain out. the crush washer for the sump drain stays in the drain hole on mine - something to be wary of. Next time I shall be changing it - I change them once in a while because.... I do

the filters on a TD5.
The centrifugal filter is pretty easy, I got right on top of the engine and they two bolts came undone OK. they seem to be captive with the cap (centrifugal Filter cap) which is good. Note which way the cap goes, there is also a notch for prying it off if you need to. You should have got a new O-ring with the centirfugal filter as well.
Dont do the two bolts up too tight as I think it would be easy to strip the threads

the main oil filter......
I couldn't get a grip on it by hand to undo it, I got a chain filter wrench and I couldn't get that around it. there isnt much space to swing it any way. cant get to it from underneather either.
Was getting frustrated.... pommy engineering (I can say that - I am one)
then I remembered the screw driver trick.
Put the flat of a large screw driver on the filter and the the shaft of the screw driver against the exhaust pipe after it exits the turbo and GENTLY undo the filter.
The flat of the screw driver should be close to you (standing on teh LHS wing) so it gets some purchase to lever the filter, not push it out of the way.

You dont want to puncture the filter and get the engine bay oily. After a few turns you can undo it by hand.

CAUTION - MAKE SURE THE PIPES AROUND ARE COOL - VERY EASY TO GET BAD BURNS

now the worse bit - you cant get the filter out with out tipping it towards you! I cut the bottom off an old bottle and was able to tip the filter towards me, catch the oil in it and then remove the filter through the availble gap.

Screwing it back in isnt too easy either.

I am wary of the auto transmission and havent done that yet.

Hope the above helps
