2026 Volkswagen Jetta Check Engine Light Codes

Common check engine light codes for the 2026 Volkswagen Jetta include P0171/P0174 (lean condition), P0300–P0304 (random/multi-cylinder misfires), and P0420 (catalyst efficiency). Each code has a cost and risk profile: unattended P030 misfires can ruin ignition coils and catalytic converters, driving repair costs far higher than an initial diagnostic; untreated P0420 often signals catalytic converter wear, which is expensive to replace if left until failure. At Larry H. Miller Volkswagen Lakewood our approach in Lakewood, CO emphasizes accurate, factory-level diagnosis to prevent escalating expenses. We explain the probable causes, repair timelines, OEM parts needs, and the immediate vs. long-term savings of addressing issues promptly. Our certified techs document the process and ensure warranty integrity; service financing is available to help manage repair costs, and our service specials can reduce out-of-pocket expense. For exact code evaluation and a transparent repair plan, schedule service with our team and protect your Jetta’s performance and value.
