Hello,
I try turn off egr, set value to 0 hysteresis 2 and 5 but now is fault - egr sensor 2 Signal too Low. Now my egr plug disconnected and I want delete egr that it would be not connected. So what’s next step? I want understand how and why change Ecu program that egr it would be full delete. Maybe someone could help :angel:
My ecu program: https://drive.google.com/file/d/15mkjei ... p=drivesdk
Thank you.

Thank you.

you can just switch off the DTC in the error code path, really simple to do

you mean with winols delete DTC fault ( only that one fault which show me vcds)? :think:

Correct

hmm... Today with vcds I saw 3 faults. One 16791 - EGR Sensor 2 and with this fault how say Blitsvis everything is clear, delete DTC with winols and that's it. But it is strange to me if there is a coincidence here that vcds show two more faults which probably not correct it would be deleted with winols. Do you agree? :?

Also now I’m thinking that this 3 faults has the same
Freeze Frame:
RPM: 798 /min
Torque: 24.0 Nm
Speed: 0.0 km/h
Load: 0.0 %

It’s very interesting.. maybe not enough set histeresis 2 and 5 to 0?
