            31-00 - Open or Short to Ground

This morning I cleaned the Maf and replaced the air filter and was no good does it look like replacing the Maf alone probably clear up the rest of the codes?

Some of them, maybe. But some of them are definitely not due to a bad MAF.

We have Wiki entries for many of those faults, have you been there? Here's a couple of examples:

PS: Since the name you gave with your forum registration doesn't match our records for the person who bought the system you're using, I need to ask you how you acquired it.

I bought it from my cousin Paul since he sold his a4. And I knew the maf wouldnt fix the ac just did a full post of the fault codes. I didnt have the tranny codes till after I did My oil change and changed out the abs module since it wasnt communicating. So all I am hopeing is if I switch the maf to get it back to where it was 2 weeks ago with only the ac code lol.
