2016 Volkswagen Jetta Check Engine Light Codes

At Larry H. Miller Volkswagen Lakewood in Lakewood, CO, we frequently diagnose common check engine codes on the 2016 Volkswagen Jetta. Typical codes include P0420 (catalyst efficiency), P0300 (random/multiple cylinder misfires), P0171/P0174 (lean condition), and oxygen sensor faults. Left unaddressed, a P0420 can lead to reduced fuel economy and potential emissions test failure; a misfire code like P0300 can damage the catalytic converter and rapidly increase repair costs. Our certified technicians use OEM-grade scanners to pinpoint codes and provide a clear cost picture — addressing root causes often prevents repeat visits and saves money long term. We emphasize transparent estimates and the use of genuine Volkswagen parts to maintain performance and resale value.
