Engine light came one while driving my 1998 Audi A4 V6 2.8L?

When i was driving last night i noticed that my check engine light was steadily on. So this morning i went to autozone to get a diagnostic of it. so the codes are P0432 and P0411. The guy told me it wasn't any major it could be my injection that need to be replace or clean up. if i get a tune up do you guys think everything will be fix?
