Hi,

can someone EGR Off from Citroen C5 1.6HDi BDM Flash, don?t want it tunned, only EGR off.

Problem is in ECU, maybe some PCB bad tracks, EGR is new, wiring is OK, but DTC's regarding EGR doesn?t even erase on my ECU.

I tried a borrowed ECU from a friend, with full BDM copy, and it's ok, so the real problem is ECU.

Thanks

so,you don't need to reprogramme egr maps,you need to desactivate egr to solve the probleme
or check the egr pin in ecu and PCB

Yes, that's it, only disable, EGR DTC's table and cycles (EGR position, etc...)

Pins are ok, i checked before, i also tested pins inside ECU, after ECU plug they are ok, i know it's an issue on PSA ECU's with EGR.

EGR OK, Wiring OK, but EGR DTC's are stored, only new ECU solves it. Or, i think... disabling it on ECU software.
