P2015 on Audi: How to Diagnose & Fix
Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 1)
1 Audi model · 1 documented issue · $150-$1,200 repair
On Audi vehicles, P2015 (intake manifold runner position sensor/switch circuit range/performance (bank 1)) is most often reported on the 2015-2018 Audi Q3 as Intake Manifold Flap Changeover Valve N316 Corrosion (DTC P2015) - 2.0 TFSI CCTA ($150-$1,200 repair). Diagnose N316 with Guided Fault Finding. Per TSB 2044003/1, replace the valve with the revised part 06H 906 283 B (which adds a fresh-air connection) and install fresh-air line 06H 133 583 F routed along the cam cover. Each section below gives the symptoms, how to confirm the cause, the fix, parts and sources for that model.
Common causes of P2015 (all vehicles)
- 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 Audi by model: symptoms, diagnosis and fix
First-generation (8U) Q3s with the 2.0L CCTA engine set DTC P2015 (intake manifold runner position sensor range/performance, bank 1) and illuminate the MIL. Audi TSB 2044003/1 (Group 24, April 2016) attributes the fault on 2015-2016 Q3 to corrosion inside the changeover valve for the intake manifold flap (N316), which is fed unfiltered air. Owners on Q3 forums report the code recurring after clearing; dealers have replaced the valve or, in some cases, the entire intake manifold because the actuator arm stop wears and the flap over-travels. Carbon buildup on this DI engine can also physically jam the flaps and trigger the same code.
Common Symptoms
- Check engine light with P2015 stored
- Code returns after clearing
- Slight loss of low-end torque or rough idle
- Flap actuator arm visibly popped past its stop
How to Fix
Diagnose N316 with Guided Fault Finding. Per TSB 2044003/1, replace the valve with the revised part 06H 906 283 B (which adds a fresh-air connection) and install fresh-air line 06H 133 583 F routed along the cam cover. If the fault is mechanical (worn actuator stop), an aftermarket P2015 repair bracket (~$60) or a replacement intake manifold is needed; run the flap adaptation (VCDS basic settings) afterward. No recall exists; this was a warranty-era TSB.

What does P2015 mean on a Audi?
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 Audi it is documented across 1 model: Q3.
How do I diagnose P2015 on a Audi Q3?
Diagnose N316 with Guided Fault Finding. Per TSB 2044003/1, replace the valve with the revised part 06H 906 283 B (which adds a fresh-air connection) and install fresh-air line 06H 133 583 F routed along the cam cover. If the fault is mechanical (worn actuator stop), an aftermarket P2015 repair bracket (~$60) or a replacement intake manifold is needed; run the flap adaptation (VCDS basic settings) afterward. Published repair guidance and available estimates are in the Q3 section on this page.
What causes P2015 on Audi vehicles?
Documented causes on Audi: Intake Manifold Flap Changeover Valve N316 Corrosion (DTC P2015) - 2.0 TFSI CCTA. Generic 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.
How much does it cost to fix P2015 on a Audi?
Published repair estimates on Audi range from $150 to $1,200 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.
