The code error is MAF and code injector, is correctly inyector coded? you verify values of MAF sensor?

[pasquale78]

error coding injectors has been successfully deleted.
DF056 does not clear the error. it is caused by a malfunction of the EGR valve in the opinion of the renault dealership.

[ruffles1986]

The MAF is original or OEM replazament is a part?, not OEM MAFS cause any problems. This my be the cause.

First carfully check MAF wiring connections.
Reprogramm ecu for DTC off is wrong way.

hello velospped and thank you for your intervention.
the car has been checked from top to bottom.
p0100 error occurs when the egr valve is flanged.
the difference between the actual value and the target value causes the error.
I saw that you are able to exclude the error of his jolidj reading the post.
if you can give me a hand I am grateful to you.
thank you and good day.

Disconnect the "refrigerant pressure sensor" and report the results. Most of the time it's faulty, brings down the voltage of the sensors, and therefore shows faults for EGR and other related sensors. I'm 80% sure this will solve your problem, and you will have to change that sensor :)

P.S. Before unplugging the sensor, check how much pressure it shows in statuses of ecu. If it shows 0000 then it's 100% the refrigerant sensor.

Even if i would disable DTC, the car would still run in limp mode with no error, because it would get incorrect data from sensors.
