In this guide we cover how to replace the primary catalytic converter (bank 2) on the base model (VR6) Porsche Cayenne (955, 957) (2003 - 2010) (9PA).
This is helpful for resolving P0431, "Warm Up Catalytic Converter, Bank 2-Efficiency Below Threshold.” This is a last resort after cleaning the catalytic converters with fuel additives and replacing oxygen sensors.
