P2015 on Mercedes-Benz
Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 1)
P2015 on Mercedes-Benz vehicles indicates intake manifold runner position sensor/switch circuit range/performance (bank 1). Au7o has documented this code across 2 Mercedes-Benz models — most commonly on G-Class, Sprinter. This code reports a range or performance problem with the intake manifold runner position sensor or switch on engine bank 1. Many modern engines use intake manifold runner control flaps that open and close to optimize airflow for low-speed torque versus high-speed power, and a position sensor reports the flaps' actual position back to the engine computer. The code sets when that reported position doesn't match what the computer commands or expects, often because the flap linkage is broken or the sensor reads incorrectly. It commonly causes rough running, reduced power, or hesitation, and on some engines the plastic linkage breaking is a well-known weak point. Typical repair costs on Mercedes-Benz range from $50 to $900, depending on the specific model and root cause.
Common Causes of P2015
- •Broken or disconnected intake manifold runner flap linkage
- •Faulty intake manifold runner position sensor
- •Stuck or seized runner control flaps from carbon buildup
- •Failed runner control actuator or motor
- •Wiring or connector fault at the position sensor
- •Vacuum leak or failed vacuum actuator (on vacuum-controlled systems)
- •Cracked or warped intake manifold housing
P2015 on Mercedes-Benz by Model
Mercedes-Benz G-Class(1 issue)
- OM642 Diesel Intake Manifold Swirl Flap (Runner) Failure2005-2018
On diesel G-Class models with the OM642 V6, the plastic intake-manifold swirl flap linkage becomes brittle and snaps, and the swirl-flap actuator motor can fail (often after being contaminated by oil weeping from the turbo inlet seal). The broken plastic rods can also be drawn into the engine in worst cases. This is a well-known weak point that triggers intake-runner control faults, limp mode, and emissions test failures. Particularly relevant to higher-mileage EU diesel examples.
Mercedes-Benz Sprinter(1 issue)
- Intake Manifold Swirl Flap Linkage Breakage (P2015)2007-2018
The OM642 V6 intake manifolds use plastic swirl/runner flaps driven by a small actuator through a plastic connecting linkage. Oil mist and heat make the plastic linkage and pivots brittle; they crack and break, leaving the flaps stuck and triggering P2015 (and runner-control codes). A failed swirl-flap motor (often from an oil leak into the actuator) produces the same fault. The result is rough idle, power loss, a lit engine light and limp mode.

What does P2015 mean on Mercedes-Benz?▼
P2015 stands for "Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 1)." This code reports a range or performance problem with the intake manifold runner position sensor or switch on engine bank 1. Many modern engines use intake manifold runner control flaps that open and close to optimize airflow for low-speed torque versus high-speed power, and a position sensor reports the flaps' actual position back to the engine computer. The code sets when that reported position doesn't match what the computer commands or expects, often because the flap linkage is broken or the sensor reads incorrectly. It commonly causes rough running, reduced power, or hesitation, and on some engines the plastic linkage breaking is a well-known weak point. On Mercedes-Benz specifically, this code is documented across 2 models.
