Common check engine light codes for the 2010 Volkswagen GTI PZEV include oxygen sensor faults (P0130–P0167), turbocharger boost control or actuator issues (P0234/P0299 range), EVAP leaks (P0440–P0457), and misfire codes (P0300–P0304). Ignoring these codes can quickly increase costs: a faulty O2 sensor will degrade fuel economy and damage the catalytic converter, turning a modest sensor replacement into an expensive exhaust repair; unaddressed turbocharger faults can lead to engine damage and major labor costs; EVAP leaks often begin as inexpensive seal or hose replacements but grow into larger emissions-system repairs if delayed.
