Audi
Type:
    Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled
Description:
    Long term fuel trim, idling, Bank 2 - system too lean
Cause:
    Fuel pressure/pump, injector(s), intake/ exhaust leak, AIR system, hose leak

Ford
Type:
    Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled
Description:
    Lack of HO2S Switches, Sensor at Rich 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 rich limit
