You should check the solenoid valve that activates the egr lung, a problem could be treated in this component. To cancel it (the EGR) simply cover the passage of gases towards the admission and so that the centralite does not detect any error, it would be enough to release the electrovalve connector and measure the resistance of the coil. Then, we would put in the connector that we have disconnected (two -way connector), a resistance with the resistance value of the coil that we have taken before.
Check the depression tubes are not cracked or broken.

Edito; In my opinion, nothing happens to the car for canceling the EGR. Also comment that the EGR can be annulled electronically through programming.
