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?
