P0471
Exhaust Pressure Sensor "A" Circuit Range/Performance
DTC P0471, sometimes indicated as P047100 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing exhaust pressure sensor "a" circuit range/performance.
The DTC P0471 code is caused by a problem with the exhaust pressure sensor circuit. The exhaust pressure sensor monitors the pressure in the exhaust system. If the pressure is too high or too low, the code will set.
Possible causes of this code include a faulty exhaust pressure sensor, a faulty wiring harness, or a faulty PCM.
If the code is caused by a faulty exhaust pressure sensor, the sensor will need to be replaced. If the code is caused by a faulty wiring harness or PCM, those components will need to be replaced.

My 2010 vw Jetta tdi is throwing check engine light codes of P0472 and P0471. Both of these have to do with exhaust pressure sensors and i think this is an environmental issue and should be subject to a mandatory recall. The local vw dealership denies any recall would cover these cel codes.
