I have measured the EGR and found it's a problem with the valve position output. between pins C & D (the resistance is too high).
But I always come back to ,would this fault course the problem described at the beginning of my thread???

an old coke can or similar is perfect for the job.

is there a guide for blanking off - i'm sure i've read something before but search for EGR found nothing?
Coke can as blanking piece between where and where? hermatite sealant? :-/

Dave Kember did an article for the ABS magazine on this, using my car for illustration, but I need my other laptop to get pics so the short version is:

1. Undo the two EGR valve retaining bolts and remove the valve.
2. Take the metal gasket and trace around it on a sheet of suitable metal (a coke can will do).
3. Cut out the traced shape and make two holes for the retaining bolts. Don't make any other holes, this is a blanking plate!
Refit the EGR valve with the blanking plate sandwiched between two new metal gaskets.

if the egr is feeding back an unlikely value to ecu (eg, stuck open/closed), ecu will try to limp mode it.  If you have electric issue with it, it needs replacing.  If its stuck open, paint stripper may help.

blanking off helps if its blowing.

Thanks The Boy
I will change  the EGR as there is an electrical problem with it,
Your posting was the one I wanted, as it explained the fault mechanism that caused the symptons I was getting.
As an engineer I hate "poke and hope" method of fault finding and just wanted to know why it was wrong.

Indeed - I would try a replacement from a scrappy.

Blanking off is completely misleading for this problem IMHO.
