P247AExhaust Gas Temperature Out of Range (Bank 1 Sensor 3)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P247A is the out-of-range verdict for the third bank 1 probe, which sits further down the aftertreatment line. It is the best documented code of this series. Volkswagen's 2014 quick-reference books for the 2.0L TDI CJAA (Golf, Beetle) compare the control deviation with an engine-speed and torque map, while the 3.0L TDI in the 2014 Touareg flags a gap between target and measured temperature above 200 K or below -100 K. Ford's 2015 diesel summary includes it with the high-side limit of about 1150 °C. A reading too high here often follows an uncontrolled soot burn in the filter, one too low a regeneration that never got hot enough.
- What you may notice
- MIL on
- Filter regeneration aborted or repeated
- Emergency mode with reduced power possible
- Likely causes

- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
