There is a rough guide on here from about a week ago, titled something like 'egr blanking plate fitted' and that is for the 1.8tdci

So Jeff have you had any issues since fitting your plate..... I'm hoping to get mine done tomorrow :D

No problems at all mate.No engine managements lights on.I scanned for codes the other day with my obd 2 scanner but nothing.All I need to do now is wait till the warmer weather gets here and strip inlet manifold off engine and give it a good clean coz Car seems to have flat spots round the 1700 rpm mark.You got a 1.6 tdci or 1.8?

Excellent...... I have a 1.6 with dpf..... Theres not a lot I haven't done on these engines but it's really the 1st experience of blanking off the egr..... Like I said I'm hoping to get mine done tomorrow..... If not Sunday.
Glad yours is going well and as soon as mine is done i will post up my results lol.

If you disconnect the sensor to install the plate couldn't a resistor of the right value be connected to the sensor so to trick the ecu into thinking all is well?

Tried it - the ECU can detect the difference in flow and if the flow stops (eg blanking plate) the ECU interprets this as a faulty EGR valve and a "lack of flow" error code is flagged up

Somebody made a circut that emulated the effect of the flow, but i don't know if this was ever fitted to a Ford

On top of that some EGR systems have a potentiometer (variable resistor) to give feedback to the ECU about the position of the (motorised) valve, if the ECU does not recieve the changes to the potentiometer that correspond to the valve/ motor, again a fault code will pop up

there was someone claiming to do remaps and an electronic EGR delete (so the EML did not come on when blanking the EGR) but this turned out not to be true

this can be done with other cars, but not Ford Euro 4s or 5s (theoretically it is possible)

So the best way with Ford euro 4 or 5s is to blank the EGR with a solid stainless steel plate and reset the EML (when it comes on) with a code reader regularly

All the above is with Euro 4/5 Ford engines

Mines a euro 4 emisions car and no eml on yet so maybe not all cars are the same...

For it to detect the flow has stopped it must be reading a sensor somewhere, I might have to do a little investigation and see how the egr works on the focus.

UPDATE: Just switced my personal opinnion of the EGR planking. Since i lifted the whole engine out of the car, i had a chance to take a closer look whats happening on the EGR, and it seems like the egr double functions as heatexhanger, and the heat goes directly to the interior heat exhanger. So, plank the EGR -> You lose some of the interior heating, witch is not desirable on nordic countries.

So, the best thing would be to allow the exhaust gasses to pass to the heat exchanger, but prevent them from going to the intake...

Yes, the EGR cooler is connected to the exhaust manifold, and as well as cooling the gasses to the valve, it heats the coolant before it goes to the cabin heater

It does not have a massive effect, (does not heat up the coolant/ cabin heater that much) but you can leave the EGR cooler connected and blank it just past the EGR cooler

I previously did this, and removed all the other EGR components, scince fitting my electric water pump, ive bypassed the cooler as well

I had considered a bypass valve/ switch for the cooler, (bypassing the cooler for summer/ routing coolant through it for winter) but i found the heating effect of the cooler wasnt that much, it would have added un-nessesary complexity and to help keep things cool for the (very expensive) pump the EGR cooler has been known to split/ leak, so ditching it improves reliability, removing the cooler and blanking it on the manifold improves performance/ efficiency/ economy/ reduces lag by reducing the volume (slightly) and reducing the heat loss between the exhaust valves/ turbine

Ok so today I fitted my blanking plate..... Like Jeff said move the fuel filter and mount out the way and it's easy.... Under 30mins in total to fit... On start up all ok so I left her to idle for a while..... No problems so off for a.20 mile road test with my Solus diagnostic system in the boot just in case..... Car feels smoother on acceleration..... I'm sure it is lol and no warning lights on at all so far. And it hasn't made the slightest difference to the heater in my car..... Lovely and toasty still lol.
I will keep on using it and report back with any issues but so far I'm well happy with it
