Understanding common check engine light codes for a 2012 Volkswagen Routan helps you prioritize repairs. Typical codes include P0420 (catalyst efficiency), P0300–P0306 (misfires), P0171/P0174 (lean condition), and oxygen sensor failures (P0130–P0167). Ignoring these codes can lead to higher fuel consumption, failed emissions tests, or expensive damage like a failed catalytic converter. At Larry H. Miller Volkswagen Tucson in Tucson, AZ, our certified technicians interpret these codes with OEM-grade tools and recommend repairs that save you money over time. For example, addressing a P0420 early may involve replacing an oxygen sensor or correcting running conditions—far less costly than replacing a converter.
