2022 Mercedes-Benz GLS-Class Check Engine Light Codes

Common diagnostic trouble codes on a 2022 Mercedes-Benz GLS-Class in Arlington often include oxygen sensor signals (P0130–P0167), misfire codes (P0300 series), and evaporative system faults (P0440–P0455). Ignoring these codes risks higher repair costs: unresolved oxygen sensor issues reduce fuel economy and can damage the catalytic converter, turning a small sensor job into a multi-thousand dollar repair; misfires cause engine damage and reduced safety; evaporative leaks increase emissions and may lead to failed inspections. At Park Place Motorcars Arlington we translate codes into clear next steps and fixed-price estimates. Our Mercedes-Benz-certified technicians use OEM diagnostics to diagnose the root cause, not just clear codes, saving you money over time by preventing repeat visits and protecting vehicle longevity. We also provide transparent pricing, warranty confirmation, and options for service financing to keep repairs affordable. Take advantage of our local convenience in Arlington, TX: quick shuttle, comfortable waiting area, OEM parts, and factory-trained staff dedicated to restoring performance and peace of mind.
