ALFA 159 DPF & EGR removal

Hello there
I want to shut DPF and EGR off from my Alfa 159 1.9JTDm model 2006 because it causes me many engine light troubles.
I was almost ready to read the ecu file with galetto 1260 clone (from China :( ) send it to a person in germany who many trust and wait for the modified ecu file from him (after I pay him of course) and then reload it to my ecu through galetto again. All this is so risky however.
Recently I changed my glow plugs for preheating diesel fuel and engine light went off. Do you think it might be the problem for not clearing DPF well (it demands hot diesel I suppose) or I still need to modify ecu and remove DPF completely?
Thanks
P.T.

Po wywaleniu filtra zamiast zmieniać soft można założyć emulator jest to chyba mniej kłopotliwe. Co do zaworu EGR to bym go zostawił w spokoju póki nie daje niepokojących objawów.
