2022 BMW 3 Series Check Engine Light Codes

The 2022 BMW 3 Series commonly reports codes related to oxygen sensors (P0130–P0167 range), evaporative emissions system leaks (P0440–P0457), and misfire indications (P0300–P0314). Left unattended, these conditions can escalate: an oxygen sensor issue reduces fuel efficiency and can damage the catalytic converter, increasing repair costs substantially; an evaporative leak can raise emissions and trigger failed inspections; repeated misfires can damage pistons and catalytic systems. At Nalley BMW of Decatur our certified technicians interpret each code with BMW-specific tools to determine root cause and cost-effective repair options. We explain short-term fixes and long-term implications so you understand the value of timely service. Choosing our Decatur dealership means OEM parts, factory procedures, and documented repairs that protect warranty status and resale value. We also highlight immediate savings from accurate diagnosis and long-term savings from avoiding secondary failures. When you're ready, schedule service or check our service specials to reduce out-of-pocket expense while getting superior, certified care.
