MK7 2.2 100 T280 fwd starts, revs 1500 2000 & cuts out

Sounds a bit like egr sticking open too, maybe blank that off temporarily to rule it out, cheap and easy.

After a significant wait for a reputable garage that takes vans to be available its been diagnosed as the EGR valve by their software. So I have a question now. How comes Forscan didn't pick that up at all? No codes nothing.

Replacing an EGR is within my skillset so I could tow it home and save myself the labour but there's more than one aftermarket option available and from the online pictures they all look the same and most say they are compatible but are they? Secondly does the ECU or new valve need coding in any way?

Well I have changed the fuel filter, the diesel in the bowl had quite a bit of black particulates in it. Refilled the bowl with clean fuel from my diesel heater tank, put it all back together and bled it at the schrader and by cracking the injector pipes off.
After quite a bit of cranking it fires up with full throttle only and revs to just over 500 rpm and cuts out after a few seconds of labouring. Now there's lots of smoke as well.

This is not boding well at all.

Need to know the year of manufacture of the van.
Mk 7 2006 to 2011 not the same as 2011 to 2014.
On the 2011 to 2014 there's no need to undo the injector pipes when bleeding the fuel system.
On any engine if the pipes are incorrectly tightened and sometimes loosened they'll break sometimes.

It is likely that if the EGR is open there would be difficulty in starting - once started it is likely the engine could keep running - the engine could not perform well at higher rpm under load. If there is an exhaust restriction and the EGR is open then the engine is likely to stop.

myself if i had the task of buying a replacement EGR .. it would be a Ford branded one, also known as FoMoCo or Motorcraft, and made by German company Pierburg, so can also be branded Pierburg.. so any of these and you are buying the top makes.

Go to cat car.info.. nearest i can get you without the year!

.. Get the part number and put it into ebay --- noting the brands above

all the best.mark

A faulty EGR valve will not cause the engine to cut out.

I have witnessed a stuck wide open egr cause engine ro cut out.

But I guess we'll never know now.

EGR valve is normally open at idle anyway and progressivly closes as RPM, throttle position and load increases...if the engine is cutting out, it won't be the EGR valve causing it.

You can remove the EGR valve altogether and the engine will still run...not happily, but it will still run.
