Hi, my name is MLrobinson from Western Canada,
I purchased my first used 2012 Q5 Audi for my daughter and me to drive. This is my first Audi and already had the control arms replaced on the front end and regular oil change and maintenance checks and a few other cosmetic things. So far love the sports car feel. I already have some issues, as the engine light came on the other day. I have access to a code reader and this what came up. P045600 passive/sporadic - Evap Emission control system (very small leak) Thinking its the gas cap?
P243200 Active/static - Secondary air injection system airflow/ pressure bank 1 sensor circuit low
01206 passive/sporadic - Signal for duration of Ignition OFF Implausible signal
00713 active/static - Left air flap motor for center vents - lower limit no reached

Are some of these codes common?
