P2010 on Mercedes-Benz
Intake Manifold Runner Control Circuit / Open (Bank 1)
P2010 on Mercedes-Benz vehicles indicates intake manifold runner control circuit / open (bank 1). Au7o has documented this code across 1 Mercedes-Benz model — most commonly on Sprinter. This generic powertrain code indicates the Engine Control Module (ECM) has detected an open or fault in the electrical control circuit for the intake manifold runner control (IMRC) actuator on Bank 1. The IMRC system uses flaps or valves in the intake manifold to vary airflow length/velocity for optimal performance at different RPMs; a circuit fault prevents the ECM from properly commanding or monitoring the actuator. On many engines (notably VW/Audi) this points to the intake manifold runner control valve/motor itself being faulty. Typical repair costs on Mercedes-Benz range from $400 to $1,500, depending on the specific model and root cause.
Common Causes of P2010
- •Failed intake manifold runner control (IMRC) actuator/motor or solenoid
- •Open, shorted, or corroded wiring/connector in the IMRC control circuit
- •Carbon buildup binding the intake manifold runner flaps
- •Damaged or stuck intake manifold runner valve/flap assembly
- •Faulty intake manifold position sensor feedback
- •ECM fault (rare)
P2010 on Mercedes-Benz by Model
Mercedes-Benz Sprinter(1 issue)
- Turbocharger VNT Actuator Failure (Boost Faults, Limp Mode)2007-2022
Sprinter diesels use a variable-geometry turbo whose vane position is controlled by an electronic actuator (PWM-driven on the OM642; vacuum/wastegate-controlled on some OM651). The actuator's electronics or worm-drive wear out, so the ECU can no longer command correct boost. The van loses power intermittently and falls into limp mode, often with under/over-boost codes. A complication on the OM642: each actuator carries vehicle-specific programming, so an un-coded replacement will itself throw a fault and stay in limp mode.

What does P2010 mean on Mercedes-Benz?▼
P2010 stands for "Intake Manifold Runner Control Circuit / Open (Bank 1)." This generic powertrain code indicates the Engine Control Module (ECM) has detected an open or fault in the electrical control circuit for the intake manifold runner control (IMRC) actuator on Bank 1. The IMRC system uses flaps or valves in the intake manifold to vary airflow length/velocity for optimal performance at different RPMs; a circuit fault prevents the ECM from properly commanding or monitoring the actuator. On many engines (notably VW/Audi) this points to the intake manifold runner control valve/motor itself being faulty. On Mercedes-Benz specifically, this code is documented across 1 model.
What causes P2010 on Mercedes-Benz vehicles?▼
Common causes on Mercedes-Benz: Failed intake manifold runner control (IMRC) actuator/motor or solenoid, Open, shorted, or corroded wiring/connector in the IMRC control circuit, Carbon buildup binding the intake manifold runner flaps, Damaged or stuck intake manifold runner valve/flap assembly, Faulty intake manifold position sensor feedback. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2010 on a Mercedes-Benz?▼
Repair costs on Mercedes-Benz range from $400 to $1,500, depending on the specific model and root cause.
