Hello,
I have a 2010 Volvo S40 with ecu VOLVO 31211076/ FoMoCo 4N5112A650BB /Bosch 0281011775/EDC14c34 with faults on EGR:
ECM-4477-EGR control,
ECM-6720-EGR control,
ECM-4490-EGR valve.
wires was checked,EGR plug was replaced with a new one,no improvement on engine,I can see an erratic control of EGR by ECU at idle
someone can help me with EGR off?PCMFlash module 77 make good checksum or is a risk to get fault 7700-checksum error?
Thank you
