Hello everybody!

Today I found a working solution for disabling EGR on my EDC15M - 2.2DTI (Omega).
With a bit of trial-and-error I found the EGR switch bit at location 39333.
Search the dump for 001 001 001 048, and the second 001 is the EGR switch bit.

Maybe this will help somebody else with a similar problem. Just to mention, this works on my Y22DTH (2.2DTI Omega), but am not sure how it is on other 2.2DTI's (Y22DTR - Vectra, Asta, Zafira or on Saabs 2.2DTI).

Thanks to all for the help! Happy tuning! :angel:

What is value 048?

Looked at Vectra 2.2dti - very similar, only the address of a little one. On my 2.0dti also the address is not good and the value 001 000 001 000 001 000 001 048. :?:

I need to EGR off vectra C but mpps wont even read id.Did you use galetto 1260 to read and write this EDC15M ?
Thanks.

Thanks.

desolder the flash, put it into programmer - the best way.

if you have vectra c 2.0dti then ecu is psg16 , if your's vectra is b 2.0dti then you can write only, for example with galleto or kwp ,but read isn't possible.

It is Vectra C 2.2DTI engine.

What i need (NAME OF INTERFACE) to downlad the oryginal file from ecu?

by OBD you can only write
