Hi mates.

I have here a Citroen C3 1.4 hdi 68cv (2009), with ecu bosch 0281012523 (9664843480). It?s an EDC16C34. I did EGR off in this car by hysteresis maps, two years ago, and car works fine until today.

Today the car is back with the fault light on and the car in limp mode and motor stops. Diagnosis machine gives DTC codes P0409, related to the egr.
In theory, the EGR is off by hysteresis maps, but not work properly.
Could someone help me turn off the egr properly? or could someone eliminate these fault codes forever?

I attached dump original and egr off by hysteresis maps. Could someone help me?

Thank you
