P2008 on Volkswagen
Intake Manifold Runner Control (IMRC) Circuit/Open (Bank 1)
P2008 on Volkswagen vehicles indicates intake manifold runner control (imrc) circuit/open (bank 1). Au7o has documented this code across 1 Volkswagen model — most commonly on Phaeton. 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. Typical repair costs on Volkswagen range from $400 to $1,500, depending on the specific model and root cause.
Common Causes of P2008
- •Failed or seized intake manifold runner control actuator/solenoid (motor)
- •Open, shorted, corroded, or chafed wiring in the IMRC control circuit
- •Loose or corroded electrical connector at the IMRC actuator
- •Stuck, broken, or carbon-fouled intake manifold runner flaps or linkage
- •Blown fuse or loss of power/ground to the IMRC actuator
- •Faulty ECM (rare)

- 3.0 V6 TDI Intake Manifold and Swirl Flap Carbon Clogging (EU-spec)2009-2016
On the European 3.0 V6 TDI, the intake manifold and its swirl flaps progressively clog with a hard carbon/oil sludge formed from EGR soot mixing with crankcase breather oil mist. The deposits restrict airflow and jam or wear the swirl-flap mechanism and its actuator/position sensor, throwing fault codes and hurting performance and economy. The swirl-flap actuator linkage can also fail mechanically. This is a well-known shared VAG 3.0 TDI weakness discussed extensively on German and UK forums.

What does P2008 mean on Volkswagen?▼
P2008 stands for "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. On Volkswagen specifically, this code is documented across 1 model.
What causes P2008 on Volkswagen vehicles?▼
Common causes on Volkswagen: Failed or seized intake manifold runner control actuator/solenoid (motor), Open, shorted, corroded, or chafed wiring in the IMRC control circuit, Loose or corroded electrical connector at the IMRC actuator, Stuck, broken, or carbon-fouled intake manifold runner flaps or linkage, Blown fuse or loss of power/ground to the IMRC actuator. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2008 on a Volkswagen?▼
Repair costs on Volkswagen range from $400 to $1,500, depending on the specific model and root cause.
Which Volkswagen models have P2008 documented?▼
Au7o has documented P2008 on 1 Volkswagen model: Phaeton.
