Fiat Freemont EDC17C49 DTC Off

[LeszE30k]

Hello!
I have got Fiat Freemont with 2,0 Multijet diesel engine, EDC17C49 ECU, 0281018312. I need disable three errors for diagnostic there:

P0520
P0521
P0522
P0523

I tried doing it manually, but DTC's come back. I'm sure file was written ok, because I readed it once again and file was identical with checksums corrected.
What I did wrong, or maybe someone can fix it for me?
Files in attachments.

Best regards!
