Polo 9N BBY - EGR and DTC off

[konq100]

Hello guys. I have strange problem with Polo 1.4 BBY with marelli 4mv ecu.

In last month I change: brand new TB, original EGR valve, PCV, all gaskets and seals on intake. All vacuum and pipes - inspected. EVAP - checked, timing - ok

I need to stop EGR and delete DTC's:

17961 (P1553)
17912 (P1504)
16785 (P0401)
16786 (P0402)
17851 (P1443)
17848 (P1440)

I try some mods to disable DTC without succes - Trouble codes is not present but MIL and EPC is active...

Thanks in advace,
G.

You probably deleted the names of the codes, for example, it was 1401, it's 0000, but not their flags. Codes and their flags are located at different addresses, can be even far apart.
