P2010 on Mercedes-Benz by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Intermittent power loss / limp mode
- Underboost or overboost
- Check engine light
- Poor acceleration
- Higher fuel consumption
How to Fix
Confirm the fault with a scan (e.g., P2010 pointing to the turbo actuator Y77/1, or P0299 underboost) and rule out boost leaks (cracked hoses, failed turbo resonator) and a bad vacuum transducer first. Replace or rebuild the turbo actuator; on the OM642 the new actuator must be programmed/adapted to the vehicle. Clear codes after repair.

Frequently asked questions
What does P2010 mean on a 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 it is documented across 1 model: Sprinter.
What are the most common causes of P2010?
The most common causes of P2010 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P2010 on a Mercedes-Benz?
Published repair estimates on Mercedes-Benz range from $400 to $1,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
