Failed Inspection P0134 P1408 P1504 P0401

Hi. My 1997 Audi A4 (not a quattro) failed inspection with codes P0134, P1408, P1504, P0401. Can anyone provide me any guidance on how to begin to address these codes. I'd like to see if I can correct these myself before going to a mechanic.

Thanks.

Google might be a good place to start. That would tell you what the codes actually mean.

You have provided generic OBD codes which are not always as accurate as Audi/ VW codes.

You might want to mention which engine you have. From the codes I would guess a 12 valve V6. (EGR is a recurring problem on 12 valves)
