Default Just cleared mine - was told 2nd air inj - is a vacuum hose problem>

makes sense cause the vac tubes on these cars are crappy at best .... they get brittle ..... I taped mine up with electrical tape until I get a chance to swap them out.

Actually only the O2's came back. SAI and fresh air blower appear to be intermittent.

Has your vehicle gone back and received the CAT ECU flash update?

Default Audi released an ECU flash update needed to fix a odd CAT error that would keep coming back...

In short, the ECU flash just adjusted the CAT threshold
