Feilkode / MIL sensorfeil eksos?

Hei, 

Fikk opp motorlampe på Audi A4 Quattro 2,0TDI CAHA Motor. 

Sjekket med vagcom og var noen feilkoder på eksos diff trykk sensorer.

Slettet disse men kom tilbake igjen etter kort tid. (Heldigvis lenge nok til å passere EU-kontroll) 

 

Noen tips til hvor begynne med disse, og delenr om sensoren sikter? 

Kan det være tett DPF? 

 

 

Kodene er følgende:
