2003 TD6 no acceleration/torque

Looks like it's the harness. Issue is there is none in the country at the moment!!!

Once you have found which one it is, take the injector out, point it into a bottle and start the engine again, there should be no fuel. At this point, unplug another injector and use its plug onto the injector in the bottle - If it still has no fuel its the injector - if it starts squirting its the harness.

I blame that episode for elevating my interest in L322s.

Mine did a harness a few months ago, car was almost undriveable at all, couldn't get over 20 k/hour and ran like a bucket of bolts at idle. It had only dropped one cylinder and the whole car was shaking.

Karcraft had several harnesses when I bought mine...... half what a local so called specialist sold a "low k better than new" harness which also turned out to be faulty.....

I was well impressed with the price - was expecting to pay an arm and a leg.

If you were local I would happily lend you my butchered made out of two spare harness to get you going until a new one shows up

Who was the specialist that you got your harness from ? and what was the cost ?
I have similar problems, one day it runs perfect, the next like a bag of bolts...

So although I was told by both local dealer and local mechanic that there was no harness in the country British Off-road on the Sunshine Coast procured one for me in 2 days. Cost was about $127 including express postage to my door. Wasn't difficult to fit....took about an hour to remove and replace. Completely resolved the problem!

Great news. :)

Replaced the intank pump with a $60 ebay BMW X5 petrol one; ok in diesel but apparently only 3/4 the output volume; of course it was 8mm outlet instead of the diesel 10mm outlet, but replaced that hose with some ubeaut 8mm non-reinforced solid-right-thru hose from hydraulic shop- supposed to be used extensively in Mercedes trucks as standard (?).

All working well now; quick starts; can run tank to empty; no more bubbles in the line under bonnet.

Some problems I had a few years back started in a similar manner and it was bad fuel that damaged injectors.
Did you happen to fill the car somewhere different?
Take a sample of the fuel and just place in a jar and look at it.
That was all I had to do to quickly determine that I had been sold adulterated fuel

Sorry folks I did not see that problem had already been corrected.
