EGR switch - EDC15C2 2.0 HDI

[Azzx]

Hey

Anyone of you have a clue how to disable EGR
without any DTC on EDC15C2 (Citroen C5, 2.0 HDI, 107 PS)?

I was messing around with the FLOW MAPs
- requested 600mg of air and it looks like
the Antipollution doesn't appear (egr disconnected from vacum).
But after while with no light on I got the DTC P0400
about wrong flow cause there is nothing to control
the air flow since I disconnected the air doser too.

I know there is EGR switch off somwhere.

Anyone?

ORG dump with FAP off.

Duty cycle 0% :).

really you've found this solution?? it works fine?

[Azzx]

Works fine, 0% on EGR, you must after disconnect the plug from electrovalve - NO DTCs.

EGR switch EDC15C2 (http://www.ecuedit.com/#p135)



1. Look the hex dumhttp://www.ecuedit.com/styles/we_clearblue/imageset/icon_post_target.gif (http://www.ecuedit.com/egr-switch-edc15c2-t31#p135)p in 8bit Text mode.
2. Set the number of columns to 10.
3. Look for: 001 001 000 000 001 000 001 000 001 048 string.
4. The first 001 is EGR Switch with/without (1/0).
5. The second 001 is Boost Control Switch with/without (1/0).

The string: 001 001 000 000 001 000 001 000 001 048 is in decimal to begin with, so no differences from yours.
