Not sure if this is related to the other question on juddering.

Doblo 51 cargo with 1.9 non turbo
idles ok, revs ok, when cold runs ok.
when warm and you take your foot off the accelerator, even just a little when cruising, it kangaroos as if it's trying to stall. ok when you accelerate again or keep the revs very high.

help!

Problem is getting worse.
According to diagnostic kit was fault in Throttle Flow Modification Valve or something similar. I think error code 510
Help
Does this mean anything to anyone?
I was recommended to a diesel specialist who said new fuel pump £750 plus labour and vat.

Second diesel guy said this valve fault was part of the pump itself.

What is the best way to scrap a Dobbie, are there specialists who would collect?

Now been recommended to a bog standard garage mechanic who says he has fixed several of these.
1 hours labour and a few pence for parts.
They are busy until end of next week but as I was going to scrap the van today anyway, it has got to be worth a try.
