did you fix your first code yet? If you just bought it and it's got 5 codes I'd be getting it back to them! Audi's are not exactly known for being diy friendly!

I currently have 3 other Audi's also, but they are pre-OBD models and owned 4 others (all CIS models) and think I got the diy end of it covered. Just thought if someone had any ideas on these codes, which all are related to fuel, bank 1/2 lean and bank1/2 rich, it could save me some time.
Thanks though for responding.

Sorry it took so long. P1128 proprietary code is common on VWs and Audis. It sets when the long term fuel trim maxes out positive. Usually it's the result of a bad MAF sensor. VW and Audi have extended their warranty to 7 years I think to cover faulty MAFs. Before changing that, check that there are no unmetered air leaks, or broken vacuum hoses or anything that might create a vacuum leak and set the P1128. Start there, with that code first.

1128 = Long Term Fuel Trim multi., Bank1 system too lean
1130 = Long Term Fuel Trim multi., Bank2 system too lean
1133 = O2 Sensor Heating Circ., Bank1+2-Sensor1 Electrical Malfunction
1137 = Long Term Fuel Trim Add.Fuel, Bank1 System too Rich
