2025 Volkswagen Atlas Cross Sport Check Engine Light Codes

Common codes for the 2025 Volkswagen Atlas Cross Sport include P0420 (catalyst system efficiency), P0300 (random/multiple misfire), P0171/P0174 (fuel trim/cylinder bank lean), and various oxygen or EVAP sensor codes. Ignoring these codes can escalate costs: a bad oxygen sensor left unfixed can reduce fuel economy and foul the catalytic converter, potentially increasing repair costs by hundreds or thousands of dollars. A misfire that’s not addressed can damage pistons or the catalytic converter, costing significantly more than timely diagnosis. At Larry H. Miller Volkswagen Tucson we offer dealer-grade diagnostics that identify code causes quickly, transparent cost estimates, and OEM repairs that protect vehicle longevity and resale value. Our service advisors will explain repair urgency, available service specials, and financing options so you can make an informed decision.
