Hi all,

I am a new Disco 2 owner. She drives mint, I only got it today and I am very impressed with how smooth it is. I do have a few questions thou if any one can help. I am trying to identify what engine I have, I know it is a 2.5 diesel, it is a 2004. I am wondering this as I have a few questions if it is a BMW engine, mainly is there swirl flaps in it as in the Beemers, I gave my brother in law a hand to remove them from his 2004 320d and am wondering if i need to do the same thing witht the Discovery. On the affor mentioned 320 there is also a Turbo Filter it has been describe to me as - I am not too sure if it exists on the Discovery. It has been clogge on the Beemer and made it sluggish. It could be a crankcase breather filter as I have found in some posts, but to be honest I don't know. I am asking this as I think she is low on power and am wondering if this would effect it. She has had a full service from the dealer, fuel filter air filter, oil etc. Is there any chance that there is a second feul filter?

Any help would be appreciated.

Joe.
 
Hi sierrafery,

Thanks for the response, possibly a silly few questions to follow. It doesn't say TD5 on it any where even in the manual. Is it defiantly a rover engine and more importantly is it a reliable/good engine?

Many thanks.

Joe.
 
The latest version what u have is a brilliant engine... it has some management issues but it can be fixed.... patience my friend, u'll figure it out in time;), plenty of threads about it ...dont u have a small Td5 badge on the taildoor's bottom...after "Discovery" ?
 
As Fery correctly says it is mostly definitely an engine conceived and built by Land Rover.

It is a 5 cylinder engine hence the TD5 and is a real cracker.

There are like on any car, a series of known faults and modifications which crop up regularly on these pages, so keep watching.

The first thing I would be doing on your vehicle is to give it (doing it myself) a full service along the following lines:

1. Engine oil and both filters change (std filter plus a rotary filter);

2. New air filter;

3. New fuel filter;

4. Check the ECU plugs for oil contamination. If oil is apparent replace the injector harness - approx £30

5. Empty coolant, flush and replace with OAT LR-specific coolant;*

6. Replace brake fluid;*

7. Replace oils in the main gearbox, the transfer box and both differentials;

8. Check and replace as necessary all brake discs and pads.

Once this is done you will have established a baseline for future maintenance and avoided many pitfalls with the Discovery.

*Items marked thus are in the official service schedule but almost never actually completed.

Enjoy your new car,

Dave

Follow that advice and it's a good start! Welcome.
 
Thanks all for the help.

I have double checked and it was fully serviced by my dealer, they are reputable enough. The didnt know about the second oil filter but i have ordered that and will put in in over the coming days. After that I'll head for the ECU connections and and have a look at the EGR.

Many thanks,

Joe.
 
A lot of people seem to think the Td5 is a BMW engine and I have often seen them advertised over here as such . However as the other posters have said it was very definitely a Rover creation .
I think some of the confusion comes about as the Td4 engine fitted to the Freelander is the same engine as in the BMW 320d etc and is a BMW engine. Many then thought the Td5 was a Td4 with another cylinder .
The crankcase filter on the Td4 did cause problems and quite a few BMWs and Freelanders suffered major engine damage when these became blocked and resulted in the sump being emptied out through the dipstick tube . By the time the oil light came on it was too late - partial piston seizure was common as a result :(. I came across it when my bro-in-laws Freelander came to grief with only 70 K on the clock . I then discovered it was very important that this filter be replaced at regular intervals - and you could get it from either a BMW or Land Rover dealer .
The D2 Td5 does not have this filter
 
Welcome to the wonderful world of Land Rover TD5 Discos. Yours will be a facelift model which was produced in the last couple of years of the production run. There are quite a few changes from the pre-facelift model, the most obvious being the headlights, but many under the skin where Land Rover learnt and modified. Mostly small things but they all add up to the car being a bit better in the reliability stakes. The TD5 is a very reliable motor and most problems when they arise are not directly engine related but ancillaries and running gear. I have a 2004 model and touch wood it isn't bad at all.

The earlier models had a "TD5" on the tailgate, but the facelift ones don't.

thebiglad has said it all really as far as preventing any problems. There are a few other things that you can't really do much about until they happen (starter motor - cheap and relatively easy to fix) and leaking sunroofs if you have them. They can fill up a weekend or two.

But really, they're a good machine and I hope it gives you a lot of pleasure.

Hi Joe, if your dealer didn't know about the second engine oil filter then they don't know TD5's imo. Don't trust that they have serviced the car fully.

If you apply my list to your car, you'll know that everything that needs doing has been done, plus you'll learn a lot more about your new toy. Don't be afraid to get your hands dirty, the sense of satisfaction and driving a car you know really well cannot be underestimated.

Dave.

Ps Do check those ECU connectors, especially the red plug and socket - if there is oil in there it is an indication of the injector harness O-rings having gone and allowing oil to track down the cable. This can cause uneven tickover and poor running. To resolve this you can either buy 2 O-rings (£2) or a new harness at approx £30. Doing the job yourself will take approx 1 hour. Then continue to check/clean the red plug until the oil residue has worked it's way through.
 
Follow the advice above and you will know then that you are getting off to a good start . As thebiglad said if the dealer didn't know about the second filter I wouldn't have much faith in their knowledge of the Td5 and its requirements .
Also there can be a very casual approach to the oils used in gbox/tbox/diffs etc and this can have a big effect on the life of those items . And I don't think I ever came across a case where brake fluid and coolant was changed routinely .
There is loads of info and help available on forums such as this from the real experts who are working on those vehicles all the time - help you won't find in any book .
And enjoy the D2 .
 
Hi thebiglad and dooroy,

I should of said that the dealer I purchased the disco from isn't a Landy dealer, I can see that the fuel filter is new and the oil seems very clean on the dipstick. That also actually converted it to springs on the rear and put in a clutch that they're giving me a warranty on. I checked the air filter this evening too and it is clean as a whistle. I did in ignorance snap the pipe from the top of the radiator to the expansion tank - I blessed it with a few sentence enhancers..... I'm actually around Loughrea by the way dooroy. I'm off to look for a pie e in the morning to the dismantlers. I have sourced the egr removal kit tho. So here's hoping it all goes well. The ECU seems to be in beside the jack. Is that normal? It is very clean looking around the connections. So I'll leave that investigation for a few days. ;-)
 
You may not have much luck at the breakers - not many D2's broken for parts in my experience . You could have a look in Buy and Sell and DoneDeal as I noticed before a few owners were advertising parts where they were dismantling themselves .
I had problems with that pipe also as it wore through . I cut it and used a piece of suitable fuel pipe to join it . Worked just fine .
Yes , the ECU is located beside the jack . Did you actually remove the plugs - sometimes it can look fine and you won't notice the oil till plugs are removed .
I'm in Gort by the way - if I can be of any further help just let me know :). Not in the trade but have been working on cars etc for years and do most of my own work .
You may also find that not many garages have much dealings with Land Rovers - and the main dealers can be expensive ( to put it mildly ).
 
Hi thought-it-was-mine,

I hadn't thought of that. Will it make a difference I wonder? There was me thinking one less thing to break down. It was done by a reputable garage tho using the proper kit so I hope not. We shall see. The policy is up in October. My wife can't tell them then and we'll see what happens. Sure it must make it safer.......
 
I'm going to try mason brook in Loughrea in the morning as they have listed as breaking one of not I'll eBay one. Yeah the local dealers can be saucy. The other car is a Honda so same dealer around here. They'd scare you with the price of stuff. Thanks for the offer. I'm originally a Tullamore man so I tend to head to Condron's in Tullamore. If you ever ned a bit brought down this direction let us know. I'm up there every week or so. Message me for a number. I'll have a look at the ECU when I'm. Doing the EGR and see.

Joe
 
I've got to second the point about the second/rotor filter. I know bugger all and managed to change it when I serviced mine (first time ever). If the dealer doesn't know about it then they've NEVER serviced a TD 5 properly!
Interesting point about ECU harness. Wouldn't mind checking mine, but where is it!!?

Hi Dave it's Dave here. The ECU is beneath the black plastic battery cover on the lhs of the engine bay as you look at the engine.

To check the ECU connectors you need to remove 1 Philips head screw, then lift the ECU out of it's space and remove the red plug and check for oil.

You can remove the oil from the plug and socket by liberally spraying them with Brake and Clutch aerosol cleaner and allow to dry (up-end the ECU on some kitchen towel to drain). However the oil will return until you have resolved the issue by either replacing the 2 x blue O-rings (£2) on the injector harness, or the whole injector harness @ £30.

DO NOT BELIEVE ANYONE WHO TELLS YOU YOU MUST REPLACE THE WHOLE ENGINE HARNESS @ £300 - THIS IS TOSH!!

Dave

Ps The residue of oil will take it's time to work through after you have resolved the cause, so just keep checking/washing out the plug & socket until no more oil appears. Or get a garage to supply and fit a new complete engine harness - total cost £600-ish!!!!! The choice is yours.

The 7 seaters came standard with rear air suspension and it was optional on 5 seaters,if its been removed on a 7 seater its classed as modified so you should tell the insurer.
