The dreaded P2015 code. If you own a 2007 Audi A8, you may have encountered this frustrating trouble code. This comprehensive guide will delve into what the P2015 code means for your Audi, its potential causes, how to diagnose it, and ultimately, how to fix it.

Understanding the Infamous P2015 Code

The P2015 code refers to the “Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 1.” In simpler terms, it signifies a problem with the system that controls the airflow into your engine. This system uses flaps inside the intake manifold to optimize airflow at different engine speeds and loads. The position sensor tells the engine control unit (ECU) where these flaps are located. When the sensor reports a value outside the expected range, the P2015 code is triggered.

What Causes the P2015 Code on a 2007 Audi A8?

Several factors can contribute to the dreaded P2015 code. These include a malfunctioning intake manifold runner position sensor, a faulty intake manifold runner control motor, a wiring issue within the circuit, or even a clogged or damaged intake manifold.

Diagnosing the P2015 Code: A Step-by-Step Guide

1. Use an OBD-II scanner: Retrieve the trouble codes from your vehicle’s ECU. Confirm the P2015 code presence.
2. Visually inspect the wiring and connectors: Look for any signs of damage, corrosion, or loose connections in the intake manifold runner control circuit.
3. Check the intake manifold runner position sensor: Using a multimeter, test the sensor’s resistance and voltage output. Compare your readings to the manufacturer’s specifications.
4. Test the intake manifold runner control motor: Apply voltage directly to the motor to see if it operates correctly.
5. Inspect the intake manifold: Check for carbon buildup or any physical damage to the manifold or its runner flaps.

How to Fix the P2015 Code on your 2007 Audi A8

Depending on the diagnosis, fixing the P2015 code might involve:

• Replacing the intake manifold runner position sensor: A relatively straightforward process.
• Replacing the intake manifold runner control motor: This can be a bit more involved.
• Repairing or replacing damaged wiring: Trace and repair any broken or corroded wires.
• Cleaning or replacing the intake manifold: This is usually the most extensive and expensive repair.

“Remember to always disconnect the battery before working on any electrical components,” advises Hans Schmitt, a veteran automotive engineer with over 25 years of experience. “Safety should always be your top priority.”
