EGR valve question, help

I have recently cleaned my EGR and MAP sensor. Made a difference on my car. Feels much smoother and improved at low revs.
I also fitted a restriction plate.
But i am unsure about the placement of the restriction plate.

On the picture in my attachment i have placed my restriction plate where the "Nr.14" gasket is. (Diamond shaped with three holes)
Should i have placed it where "Nr.9" or the most right-hand placed "Nr.6" is?

In that way the restriction comes before the flow enters the EGR if i have understood it correctly? Maybe that is better?

Doesn't really make a difference to be honest. Personally I'd stick it closer to the manifold. But whichever is easiest tbh.

I just come to think of that it might be better to have the restriction plate before the EGR valve.
To reduce build up in the EGR...

Any thoughts on that?

My restriction plate is square and fits after the EGR valve itself... this means the Valve still gets the full brunt of the crap from the exhaust and gets pretty badly caked up, last time i cleaned it, it was blocked completely. I'm sure fitting a restrictor closer to the exhaust side would give you longer between cleans but how it will affect the build up on the exhaust side i dont know but i'm sure that will be more dificult to clean.

Just fitted a complete blanking plate just before the EGR sensor.
How long does it take before the fault code comes up?
Just took it for a 10 minute drive, no fault codes.

My car has had a remap (for more bhp).
Could it be that the EGR has been deleted as well?
But there is no blanking plates on it.... Just one restrictor plate after the EGR.
Does the EGR valve itself work as a blanking when it is deactivated?

Can it be tested by unplugging the connector that goes to the EGR valve?

Just got the fault code...
How will the egr dongle work with clearing the fault code?

Make sure the dip switch is set on the dongle for clearing EGR code.
plug it into the OBD2 port in the car (behind a panel to the right of the steering wheel on right hand drive cars)

If the code is showing when you plug the dongle in it should disappear after a couple of minutes/seconds

even with the dongle you might still get the EML shown on the dash but it will be very rare and won't stay on for long.

It will only clear the faults associated with the EGR, so if you get the EML showing and not clearing you might have another issue which needs resolving.

I blocked mine from the exhaust end of things and between the manifold and the egr.

I looked at that option. But to mee it seemed a bit difficult to do.
But it is doable and accessible?

Ignition off! You need to run the whine and then turn it off leave the keys in for around 10sec (every time! it's when it deletes the error codes), remove keys. Next start the eml should have gone
