407 egr valve problem

Hello 2010, I have 407hdi, even though we have changed the egr valve, the fault lamp does not go out.

Whether this process was done in a private service, my authorized service system was made ..

the special service changed in the program could not be discarded, we canceled the egr from the brain elsewhere . everybody says something else, one says the brain does not belong to this vehicle, the other says the fuse box does not belong to this vehicle, another says it is installation

Well, my teacher has a long time, this special service masters are such that, first of all, my advice is to go to a good authorized service and find out the suitability from the chassis number to find out the source of the problem and whether the parts fitted on the vehicle are compatible. you also learn why the logo originates. There is no one to do there, you will get the price and you will learn the problem. take the part of the teacher from where you changed the egr valve, maybe it was not a malfunction so there may be a problem in the sockets. Did you ever look at the electrical installation

they looked at everything best to restore the vehicle to the service, I think

just like that, you can book it back to its original state, they want help from France for problems they cannot find in the service. Give 50-100 TL to the service, whatever the problem is, I hope your problem will be solved as soon as possible.
