Hello very good to see if you can take a hand because I am a little lost and I do not find it I have a
Renault Laguna 2 of 2004 6 speeds 1.9 dci 120 hp

and the ECU When passing it through diagnosis I send me these two faults P0C82 and P0C84 state searching online and the forum and I do not find that it can be producing that failure to review where it is the fault.
