Peugeot 208 bluehdi 2017

[VCPlou]

Hello everyone from Greece. I want to apologize for my bad English. I have a Peugeot 208 2017 1.6 bluehdi 75 hp. January i did a dpf clean. The next day i took the car in the national road and adblue check engine and key lights came up. Until now nobody can tell me what's the problem with my car. I have erased the codes but every time i got my car in the national road lights open. In the city the car is working normal. I have error codes P20EE and P2204. P2204 is nox sensor but before one week i went to a guy to see the car and told me that nox sensor is working. Scr fluid was empty and he refill it. I took the car again in the national road the lights again came up with P20EE. He told me that adblue tank is working and i have also replaced adblue injector 250€. From January until now when i open the adblue tank to see how much fluid has inside is full all the time. 6 months now. So i try to understand where is the problem. He told because scr fluid was empty adblue tank has stopped that's why nox sensor gives error code. But i still have P20EE in the car.

P20EE can in some circumstances mean that the engine ECU software needs an update, along with the reinitialisation of the deNOx system fault codes. This should clear the fault if there are no other associated faults.

P2204 can mean replacement of the NOx sensor which you have done, but it must be initialised with a professional level diagnostic tool that has up to date software for the vehicle concerned.

Nox sensor is not replaced. He just told me that the diagnostic tool shows that is working. Because scr fluid was empty he said that adblue tank stop automatic to work that's why show this error. Thanks for your answer. If i have news i will inform.
