Audi
Type:
    Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled
Description:
    Long term fuel trim, idling, Bank 1 - system too rich
Cause:
    Fuel pressure, injector(s), EVAP canister purge valve

Ford
Type:
    Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled
Description:
    Lack of HO2S Switches, Sensor at Lean Limit Conditions
Cause:
    Engine running in closed loop, then the PCM detected that the HO2S-12 signal did not switch because the fuel control system is at its lean limit
