RENAULT MODUS NOTICE: "Check Depolucion"

Hello everyone, I write to see if anyone knows something, or they have any knowledge of what can happen to my car.
It is a 1.2 16V Motor--
d4F Network is due to the FAP (antipolution filter) I have done what it puts in the circular manual for a time for the filter to have temperature and regenerate, although I think that is indicated for diesel cars, not for gasoline. It has not improved anything.
Another possible cause can be the EGR, but everything I have been able to read is produced in diesel engines.
This engine uses a single coil, not the others of pencil that has failed so much in other Renault models.
I already think that it can be, a spark plug, an injector or I do not know what more. In the Renault they have told me that the diagnostic machine does not miracles since the failure is not recorded on the computer.
So after all the tocho I ask, do anyone know anything?
Thank you very much antcipously.

Hello, I will see you to be honest, as a nissan tube technician, a problem with a 150 hskai qaskai in Nissan says that you have to replace the oil and filter and I do not have to replace the exhaust output line greetings

Hello, how are you, look, I tell you something that I have known for a while, the new cars, especially Feonians, bring a system to throw less gases which works by throwing a hu I am wrong to rectify me, but to a friend of mine exactly the same thing until the house was told that it was of that.

Greetings I hope I could help

Hello everyone again, well, then I clarify the breakdown so that if it happens to someone who can solve it.
It was tried to regenerate the FAP, according to those of Renault, at 80km/h 20min despite being a gasoline I think it does not carry fap, the question is that it was not fixed. And it may be that the cayalizer has touched it.
He changed the oil and spark plugs (the originals, he also touched him) did not arrange the same pull and low power.
The diagnostic computer said that the cylinder No. 1Tenia combustion failure, and when removing the spark plugs to change them I saw that the cylinder nº1 and nº4 were burning badly, the very black spark plugs.
What made me think even more than the coil, when the part of these two cylinders was double (they are couples cylinders), because I had some intermittent failure because I was not accused only when I needed to give more current.
The next thing was to look for a "non -original" coil and try, the car change totally, the problem is corrected as before and does not pull.
So this is what I can tell you, by the way, the Beru coil, it seems well.
Thank you very much to all who have contributed your comment.

thanks for the information. To diagnose this type of problem, the help of an oscilloscope will be eager, since you can check the decidal electronic component switching. I am soping that they could not diagnose it in the agency. Greetings
