The dreaded P2015 fault code. If you’re an Audi A4 TDI owner, seeing this code pop up on your diagnostic tool can be a real headache. This guide provides a comprehensive breakdown of the Audi A4 TDI fault code P2015, helping you understand the problem, diagnose it, and explore solutions. We’ll cover everything from the most common causes to DIY fixes and professional repair options.

The P2015 fault code typically indicates a problem with the intake manifold runner position sensor/switch circuit, specifically Bank 1. This sensor plays a crucial role in regulating the airflow into the engine for optimal performance and fuel efficiency. A malfunction can lead to various driveability issues, decreased fuel economy, and even potential engine damage if left unaddressed. Let’s dive deeper into this common Audi issue.

Understanding the Audi A4 TDI P2015 Fault Code

What Does the P2015 Code Mean?

The P2015 code specifically refers to the “Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 1”. This indicates an issue with the sensor itself, the wiring harness, or the motor that controls the intake manifold flaps.

What does “Bank 1” signify? In engines with multiple cylinder banks (like the V6 found in some A4 TDI models), Bank 1 refers to the side of the engine that contains cylinder number one. Knowing this is essential for accurate diagnosis and repair. For those with the audi a4 b8 2.0 tdi engine code, understanding bank configuration is equally important.

Common Symptoms of P2015

Experiencing any of these symptoms alongside the P2015 code could point to the intake manifold runner position sensor as the culprit:

• Check Engine Light illuminated
• Reduced fuel economy
• Loss of power, especially at low RPMs
• Rough idling
• Hesitation or stumbling during acceleration

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

1. Retrieve the Fault Code: Use an OBD-II scanner to confirm the P2015 code.
2. Inspect the Wiring Harness: Check the wiring and connector for the intake manifold runner position sensor for any damage, corrosion, or loose connections.
3. Test the Sensor: Use a multimeter to test the sensor’s resistance and voltage according to the manufacturer’s specifications.
4. Check the Intake Manifold Runner Control Motor: The motor itself can fail, causing the P2015 code. Inspect it for any signs of damage or malfunction.

Knowing your specific audi a4 3.0 tdi engine code will help in sourcing the correct parts. Sometimes, knowing the audi tt engine code can provide helpful context for similar systems.
