Most Reported On
P2008 is an OBD-II diagnostic trouble code meaning “Intake Manifold Runner Control (IMRC) Circuit/Open (Bank 1).” P2008 is a generic powertrain code indicating the engine control module (ECM) has detected an open or out-of-range electrical fault in the Intake Manifold Runner Control circuit for Bank 1. The IMRC system uses an actuator (solenoid/motor) to open and close runner control flaps in the intake manifold to optimize airflow, torque, and emissions across the RPM range; this code means the control circuit is not responding as commanded. This code is most commonly reported on 2005-2018 Mercedes-Benz G-Class (G 320 CDI, G 350 CDI, G 350 d, G 350 BlueTEC), and 2009-2016 Volkswagen Phaeton, with repair costs ranging from $200 to $1,500.
