P200A is an OBD-II diagnostic trouble code meaning “Intake Manifold Runner Performance Bank 1.” P200A indicates the engine control module (ECM) has detected that the intake manifold runner control (IMRC) system for Bank 1 is not performing within its expected range. The intake manifold runners (swirl/tumble flaps) adjust airflow into the cylinders to optimize fuel atomization and combustion across different engine speeds and loads, and this code sets when the actual runner position or resulting airflow does not match the commanded value. This code is most commonly reported on 2006-2015 Mercedes-Benz M-Class (ML320 CDI, ML350 CDI, ML350 BlueTEC, ML250 BlueTEC), with repair costs ranging from $150 to $700.
