Fault codes

[j_jabbar]

Hi Avensians, anyone decipher these 2 codes and are they related to one fault? If it is just the EGR valve is there any way I could get the part number/code without diving into the engine? Car : 2005 2.0 D4D T4 Hatch. Thanks folks. WOW just realised, haven't been on this forum since 2013...my first fault showing up.
