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.

Likely causes

Overloaded particulate filter burning off too fast

Regeneration not reaching target temperature (VW low-side check)

Probe aged and misreporting

Symptoms

MIL on
Filter regeneration aborted or repeated
Emergency mode with reduced power possible
