Hi all,

There could be a one digit switch in EDC16C34 PSA ecu to turn off completly the function of the EGR.

As I know there is a diagnostic checking before you turn the car on, and there have to be a diagnostic parameter to check a component is it okay or not.
I would like to find this switch to turn off the EGR.
Like in EDC15C2 8bit switch set to 0 and you are able to take the plug off and no error code in the ECU.

I know the 2 hysterisis set to zero but it is not a proper way to turn off because if You have short circuit you get trouble codes (if not removed).

Is there any advice from guys? :)

I try look on Damos and try to find. Could it be that switch I'm looking for?
How can I set to disabled?

Thank you

This may help you... I just read it and very informative for me.

this is the post what helps me to find something but EDC16C39 OPEL/ALFA/SAAB and EDC16C34 PSA sadly not that much similar.
Thanks the advise :)
