edc17cp02 bmw 320d aut egr off

Hi to all!
I have again problems with egr in Bmw edc17cp02.
I have tried by myself but it doesn't works.
I know where are hysteresis maps but egr have 4dtc that are:
4CAE
40D4
4C9E
4501

Any help really appreciated.
This ecu has SVTQL 428.7 NM to everybody who wants to get more than 403.2 Nm typical limit.
Regards!!!
