Asked my mechanic and he said it sounds like the wire loom on the injectors.
Is this a costly fix

Intersting... i thought they did the production fix in 2003. Maybe yours missed out on the fix

Much smoke from the back as it did it?

Check the turbo hoses. They can soften with oil/age & can suck in under acceleration.

also the turbo hose above the centrifugal filter can pop off......
just double check this hasnt happened.....

Check the ecu wiring connector under the seat for oil. Not a dear fix, replace the injector wiring harness about $135. The oil can be cleaned out of the engine wiring harness, this harness is significantly dearer and a lot more involved to replace. Keep the old injecto harnes, flood it with contact cleaner and then replace the o rings, seal up the harness with good silicone and keep as a spare.
Mine is a 2000 model and the new one I replaced it with that is supposed to be the cure to all this is identical. I seriously do not believe that they could make one that would not suffer from this problem after a prolonged period as the o rings will wear eventually through vibration.

wouldnt sikaflex be better than silicone....?

mmmm sikaflex! its the s it!

Hi Bigmac.
That sounds the same as what recently happened to my Defender 110 Td5 and it turned out to be the Throttle Potentiometer. I had first thought it was dirty fuel as I'd topped up from someone elses jerry but it was such a sudden "missing" I then thought it may be electrical.
Checked all electrical connections including the loom into the ECU but no problems with any of it.
Got it back to Perth and to the after market service people and it cost around $500 to be Testbook checked and rectified.
I've found out since that someone else I know who had a Td5 Disco had exaclty the same symptoms.
He now drives a BC 4.2 Nissan and is much happier!
I'm thinking that might be the way to go.
