There's not a lot in the way of electronics that will stop a TD5 - ecu, throttle position sensor and crankshaft position sensor, and the throttle position sensor seems the most likely to fail and not without reason due to its operation.

Hi Bigmac.
I thought the symptoms you described were the same as I experienced a couple of months ago.
What peeves me is that no one except in a very few places in WA, can diagnose what has gone wrong. I suspect that's the same throughout Australia.
Seems to me to be a waste of time owning a vehicle you can't trust and which will require expensive haulage to diagnose/repair plus possibly air fares and accommodation as it did us.
I'm seriously thinking of getting rid of it for a pre computer era vehicle even if it is a rice burner as I've no intention of getting stuck somewhere again.
Pity because we like the vehicle but there comes a time when you have to make a decision like this.

I have a 2003 TD5 Disco and have inquired about the Elmscan 5 scanner interface for a PC and was told by the Australian distributor that it has been tested on a 2003 TD5 Disco and works well. I intend following this up and buying one ($200) if it does indeed work so that I can extract fault codes, leaving only the task of ringing a dealer to find out what the code means.

But carrying a spare $250 throttle position sensor doesn't seem too unreasonable, especially as I will probably have to replace it from time to time.

I am quite prepared to carry this in stock for our outback work. What's more, I'm happy to get all three items mentioned by graeme. If I cost to a stop in the desert I'll just start replacing them in order of difficulty until it fires.

We are also investigating the purchase of a rovacom lite as I travel with a number of other people that have LR's and we'll all share the unit.

It doesn't matter what car you buy there will be weaknesses.

55 pounds if you're willing to buy one from the UK, that's about $130 plus postage.

The fault didn't stop the TD5 it ran fine before I could get it fixed. It was only a problem at high revs in high rang. didn't seem to happen in low rang high revs. They also found an overboost when the put it on the notebook cleared that and it has not come back. they said it was from the accelerator fault.
All happy again as it is my work vehicle and I can't do without it. if it stops I don't get paid every one at home goes hungry all get unhappy

Start saving now if you get a Nissan for the time the fuel pump s...ts itself.

All cars have problems, also you thought Land Rover were expensive for parts, Their not a patch on Nissan and Toyota

A diesel guzzling dinosaur.

the Tdi is a superior engine and the Td5 is a far superior engine.

One of our work vehicles is a normally aspirated 4.2 and while it has been reliable it is very down on power and Drinks diesel, their 3.0 litre turbo is better but the vehicle is so bloody heavy.

The defender is a unique package, robust running gear and economical compact turbo diesel engine.
I looked at everything else and it fitted the bill (despite the poor above the sills finish)
