I have a fiorino with light engine turned on and errors P0401 and p0402
? a 8df the 1.3 second-generation.

the problem ? on the egr for the codes that I have read.

the first thing I changed l egr, even if on these models ? the first exchange.

after a trip, here again we have the light turned on, and the same errors.

have you ever had any bega similar?

Could be the velocity of the egr valve on the intake manifold blocked off, remove the tube input with the three bolts from 6mm and controls the velocity stack ? dirty smontalo and clean it if the manifold ? blocked smontalo and clean it well, clean well the sensor turbocharger mounted on it

I would check the hoses to the turbo and the intercooler... as well as the intake manifold that many times the hole on that type of car.

the intake I have to look at, but ? was one of those classic works on the fly, which then should not be has a good end.
now when I see fit to do these checks that I have recommended.
let's see...

Make sure to check also the wiring that connects to the egr valve if there are wires that make contact with one another due to a filleting or the plug does not connect well

I say close all from the map and delete it and solve in a very short time and I have to say that the car should be even better,

then, a correction address exclusion egr marelli mj8df. view the map as a Motorola 16-bit address 1DCF66 and bring the value to be 14238 to 35630. I apologize for the oversight.

certainly, as I understand how to post images, I still don't have a lot of confidence with this forum, but if someone can explain to me how to do it?

hello,I realize that is a discussion to be a bit dated,but can I ask you for help on a egr that I can not locate nor position value?

Why should open another discussion on the same topic? Better to have everything in the same topic. Rather, he must attach his file to see to find the right address
frenk85
It is the one that counts is the information.
Was to make it more "ordered" given that the discussion is dated.
