Peugeot partner Edc16 c34 Egr off and Dtc

[Proudish]

I have replaced my EGR on my Peugeot Partner. EDC16C34. Because I got error codes. But it did'nt help. Is there any kind soul out there who can help me. EGR off and remove the fault codes P1162, P0401, P0490.
I have a Kess V2 program K-suite.

Thank you very much/Johan
