I just went to get my RS6 with a eurocharged tune get emission testing today at the Oregon DEQ but it failed on multiple tests. The problem was that their readers were coming back saying that multiple systems could not be read (like O2 sensor and EGR, fuel system) and were not returning information. I ran my vagcom right before I went there and I was not getting any abnormal codes and I have no CEL. Could my tune cause problems with them trying to read the ECU. I have not coded out any of the emission systems. Should I just flash back to stock and have them try again. I can't imagine that the tune would create problems with reading codes because it is still using all of the cars systems. Could my battery be going bad causing problems with reading the ECU. Could my ECU be going bad. Maybe I should disconnect the battery and let everything reset itself. Anyone have a similar issue.
