I know that the first switch is on address between 11B02 - 11B5E, but there are a lot of them :-(

@digi men: I will try your second solution but in this time I dont have many attempts for testing.

@digi men: Still dont work - error P1403

I dont have idea anymore,this are all me known location , do you have or some friend MB c3/4 star diagnosis, i think whit this toll you can deactivate the egr, ask someone !

[Babos]

we say that is hard job in one car all work fine but for same not working.
same times best joice is replace egr.

[kennfeld]

i think it work only with a working egr then you can put off once not working you need to clean etc before to switch off

No, I close EGR in map and now everything OK - no DTC P1403. But I know that is not EGRoff but only Close solution like in VAG cars with EDC15P.
If anybody have fully working solution please contact me via pm.

I tried 16eddi67 version, but there's no changes - same DTC, and on the actual values EGR ratio changes from 3% to 95%....
