2024 Volkswagen Jetta GLI Check Engine Light Codes

At Larry H. Miller Volkswagen Tucson we see common codes on the 2024 Volkswagen Jetta GLI that point to predictable causes: P0420 (catalytic converter efficiency), P0171/P0174 (fuel trim issues), P0300–P0304 (misfires), and O2 sensor faults. Ignoring these codes can compound costs — a failing O2 sensor often leads to poor fuel economy and higher emissions, while an untreated misfire can damage catalytic converters, turning a modest sensor replacement into a multi-hundred-dollar exhaust repair. Our certified technicians diagnose codes with OEM-grade tools, explain repair options, and prioritize fixes that protect your engine and wallet. In Tucson we combine fast diagnostics with genuine Volkswagen parts, and our service advisors will outline immediate savings from prompt repair and the long-term value that comes from proper factory procedures.
