Trouble Codes
I have two codes on my 2000 A6 2.8L Quattro. The first is P1296 (Cooling system malfunction) and P1423 (Sec.Air Inj.Sys.,Bank1 Flow too Low). Any possible ideas what is causing these codes to come up and how to fix them. I was told that the P1423 might be due to bad O2 sensors. This true?
