cuts out under load CRD 3.0

[happygu]

I did boost it up a bit maybe too much, I just went out and wound it back down, I will give it 1/2 hr and give it a run, you maybe a patrol saver it was gone....

Did you adjust the Turbo Actuator Rod ( in Red ) to adjust Boost, as this shouldn't be touched

The boost adjust is shown the Blue Arrow

Anyway anyone got a clue how to fix this .....................

Blue arrow is the one I adjusted its a pain to get too.
There was a young mechanic under the bonnet the other day I think he may have played with it as it has scratches on it. Would that cause the problem? And how would I fix it?

This is driving me nuts Ive tried everything and still no go. Someone must have an idea im out of them. As I said Ive spent a fortune on this thing to go no where only ones getting enjoyment are the mechanics rubbing there hands together.

Scangauge or a boost gauge fitted and get some certainty as to the boost it is actually creating , also the MAF may be dodgy causing the problem

Ox,

Can you get next to another CRD, and pop the bonnets of both, and compare the Turbo Actuator Rods for length, to see if they are approximately the same.

I don't think it takes much to affect it, as my Turbo Actuator Rod was slightly bent, and this caused it to go into limp mode .... no power when loaded up ( when it popped into limp, it was 80 klms an hour up hill, but you could get to 100 cruising on the flat )

yeah I can we have a wagon the same model so I will measure the gap and set it the same.I just cant work out why it stalls out all together if its in limp mode, its like theres no fuel or air getting to it but checked it all and its all good, the only thing the maf when unplugged it ran the same as if it was plugged in, I allways thought they would shut down if there was no air passing through it ??

X 2 with Boots get your hands on a Scangauge this diagnostic tool will pin point your problem very quickly.
Not very expensive either. Any faults that show up you can re-set, That's what I'd be doing

Try to hook up a temporary boost gauge, adjust your boost to 10psi at 2000rpm
this is ball park, fine tuning can be done later
Max boost should be 12-15 psi and spikes of up to 20psi are not abnormal
once you have the boost where it should be, you'll now have a starting point

I have set the boost back to exactly the same as the wagon by measuring with micrometer still the same starts failing in 2nd then 3rd at about 2500 rpm it shuts down turn it off for 2 sec and starts straight up it is something simple I hope just finding it.

Dodgy TPS perhaps . some CRD models have had issues . you may be able to swap with the one in your wagon .
