EGR disable for D40 v9x engine

When my EHR failed, the only sign initially was the cruise not setting. Something to do with the maf readings not matching the EGR flow readings. Not sure how the EGR measures gas flow.
It is possible that the delete didn't work?

Yeah possible. Im going back on friday to have it checked and plugged in again.
What have you done to your EGR? Just plated? Or electronic delete?

I put a new one in. The old one lasted 8 years and 240k Kms and only had a small soot build up, so no benefit in trying to modify anything.

Yeah he had deleted 2 of the egr codes but missed a third. Looking like it is all disabled now for me. So i have a plate and a ecu delete

Back to the thorny egr valve.
Has anyone been able to determine how the egr flow rate is actually monitored please?

On the postd & egr videos to date seems like the ecu sends a series of pulses to step the egr open a certain amount and reverses the polarity to step the valve closed.
Beno's post says there is a hall effect near the valve shaft so guessing is feeding back the current position to the ecu.
But how is the egr gas flow rate monitored? or is the position signal keeping the ecu happy?

I would really like to find out how this sucker really works.
For those anyone thats replaced one, and apart from carboning up has someone pulled one apart to see what else fails in them?
Any pics would be really appreciated.

curious Ian again.

Not a clue but i am loving the ute without the egr still
