Hi all, got a bit of an issue with a 2008 170 dsg tdi, had faults with egr, replaced with genuine new one. still has fault:19586/P3130/012592 - EGR System: Regulation Range Exceeded

it deletes but comes back within 60 seconds. I've tried to carry out egr adaptation, but I cannot change the value from 128.
Can anyone help me on this one????

Thanks.
