2011 Rolls-Royce Phantom Coupe Check Engine Light Codes

In Boston, Rolls-Royce Motor Cars Boston handles diagnostic codes for the 2011 Rolls-Royce Phantom Coupe with precision and care. Common codes include P0300 (random/multiple misfires), which can quickly damage catalytic converters if left untreated and may lead to repair costs from several hundred to thousands of dollars; P0420 (catalyst system efficiency low), where delays usually escalate to full converter replacement; P0171/P0174 (lean/too much air), often tied to vacuum leaks or fuel delivery issues that degrade fuel economy; and P0455 (large EVAP leak), which can be inexpensive to fix if caught early but allows fuel vapors to escape and can trigger further emissions test failures. Our certified technicians use factory diagnostic equipment to identify root causes, explain repair timelines and costs, and recommend the most cost-effective path forward. Choosing Rolls-Royce Motor Cars Boston in Boston, MA ensures access to OEM parts, technician certification, and a service experience tailored to Phantom Coupe owners — balancing immediate savings via accurate diagnostics and long-term value through correct repairs.
