2026 BMW X1 Check Engine Light Codes

In Medford, drivers bring their 2026 BMW X1 to Herb Chambers BMW Certified Preowned Medford for precise code diagnosis and lasting repairs. Common DTCs include P0420 (catalyst system efficiency), P0171/P0174 (fuel trim lean conditions), P0300 (random/multiple misfires), and P0455 (large EVAP leak). Ignoring P0420 risks catalytic converter damage that can escalate into a $1,000–$2,500 repair; untreated misfires (P0300) can damage pistons or catalytic hardware, costing hundreds to thousands. EVAP leaks may cause emissions failures and poor fuel economy; left alone, they contribute to wasted fuel and failed inspections. Our Medford team uses BMW factory scanners to read live data, identify root causes, and show you the problem before we act—reducing unnecessary parts replacement and delivering immediate and long-term savings. Book with confidence: OEM parts, certified technicians, and transparent estimates mean faster turnaround and better resale value.
