2024 Mercedes-Benz AMG GT Check Engine Light Codes

The 2024 Mercedes-Benz AMG GT presents a set of codes technicians see frequently: P0300 series (random/individual cylinder misfires), P0420 (catalytic converter efficiency), P0101 (MAF sensor), P0171/P0174 (fuel trim/lean condition), P0442 (EVAP small leak), and oxygen sensor faults. Left unresolved, a misfire can overheat and damage catalytic converters, turning a modest sensor replacement into a four-figure repair; EVAP leaks can allow fuel vapors to escape and trigger drivability concerns; poor fuel trims or MAF faults reduce fuel economy and accelerate component wear. At Mercedes-Benz of Chesterfield in Chesterfield, MO, our factory-trained technicians use OEM diagnostics to read live data, identify the primary fault, and recommend the most cost-effective repair path. This approach reduces unnecessary parts replacement and provides immediate and long-term savings compared with repeated visits — we often deliver lower total cost of ownership than indie shops by preventing cascading failures. We back repairs with dealership warranty coverage; if a condition is warranty-covered, executing the repair here preserves that protection.
