98 TDI 3 trouble codes
 

I pulled three codes tonight for my check engine light, this is what they are can anyone tell me what part or parts and if I can it myself. I can most things on vehicles I just don't know parts on these new ones.

1. 00560 EGR System

2. 00575 Intake Manifold Pressure System

3. MAF Sensor Signal Fault

I think 1 and 3 are easy fixes from what I understand about these new vehicles, any help would be gratefull. Thanks
