The P2015 error code is a common issue found in Volkswagen vehicles that use the EA888 engine, such as certain models of the VW Golf, Audi A3, Seat Leon, and Skoda Octavia. This code refers to a problem with the intake manifold runner position sensor. Here's a step-by-step guide to address this issue:
1. why indicate error code P2015?
The P2015 code indicates a malfunction in the intake manifold runner control. The intake manifold system has an actuator that adjusts the length of the intake runners, optimizing airflow into the engine. When this system malfunctions, the engine control module (ECM) triggers the P2015 error code, signaling that the manifold flaps are out of their expected range.
2. Potential Causes of P2015 code
The P2015 issue is typically related to:
- Worn or damaged intake manifold actuator: Over time, the actuator wears out and the flap mechanism can move beyond its operational limits.
- Sensor misalignment: The intake manifold position sensor may get stuck, incorrectly registering the runner flap's position.
- Carbon buildup: Over time, carbon deposits can form around the intake valves and the manifold flaps, affecting their movement.
3. Proposed Solution
Solution 1: Install a P2015 Repair Bracket One of the most common and cost-effective fixes is to install a P2015 repair bracket, which limits the movement of the intake runner flaps to their normal operational range. This prevents the actuator arm from moving out of the specified range and triggering the error code.
- Procedure: The repair bracket can be installed with basic tools, and it's often a DIY solution for those with mechanical experience. It prevents excessive movement of the flaps, thus eliminating the P2015 code.
Solution 2: Clean the Intake Manifold Carbon buildup can restrict the flaps' movement. Removing the intake manifold and performing a thorough cleaning with specialized cleaners can restore smooth operation.
- Procedure: Use a carbon-cleaning spray or brush to remove deposits from around the flaps and intake valves. Ensure everything moves freely before reinstalling.
Solution 3: Replace the manifold position sensor, here is the link with orignal part:

Solution 4: Replace the Intake Manifold If the intake manifold has severe wear or damage to the actuator system, it may be necessary to replace it entirely.
