P0AD6Hybrid/EV Battery Pack Air Flow Valve A Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0AD6 flags that the air flow valve A of the battery cooling does not behave as expected: the circuit is intact, but position, travel or the learned end stops do not fit the command. Audi documents exactly this code as P0AD600 on the 2012-15 Q5 hybrid (TSB 2038152): a software error made the battery management module J841 lose the learned end stops of the air supply valve, electric and hybrid drive were disabled, and a software update to version 0543 fixed it. CARB 1968.2 calls for functional monitoring of battery thermal management. Pure circuit faults are P0AD5, P0AD7 and P0AD8. Besides software, a sticking flap or a slipping actuator can cause it.
- What you may notice

- Likely causes
- LikelyBattery controller software loses learned end stops (Audi Q5 hybrid, fixed by update)
- PossibleFlap binding from dirt or a deformed duct
- PossibleActuator gears or position feedback worn
- RareEnd stops not relearned after battery or actuator work
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
