P0264 Audi Code - Cylinder 2 Injector Circuit Low
Quick Answer
The P0264 diagnostic trouble code (DTC) for Audi vehicles specifically refers to an issue with the Cylinder 2 Injector Circuit registering a low voltage. Common causes include Faulty Fuel Injector: The most common cause of a low voltage condition in the Cylinder 2 Injector Circuit is a defective fuel injector that is not operating correctly, Wiring Issues: Damaged or corroded wiring connections leading to the fuel injector can disrupt the electrical signal and cause low voltage readings, PCM Malfunction: A problem with the powertrain control module (PCM) responsible for regulating the injector circuit could lead to voltage irregularities. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0264 Audi Description
The P0264 diagnostic trouble code (DTC) for Audi vehicles specifically refers to an issue with the Cylinder 2 Injector Circuit registering a low voltage. In simpler terms, this means that there is a problem with the fuel injector in the second cylinder of the engine not receiving enough electrical power to function properly. Fuel injectors are crucial components responsible for delivering the precise amount of fuel into the combustion chamber for efficient engine operation. When the injector circuit is not functioning correctly, it can lead to various performance issues and potentially cause long-term damage if left unaddressed.
Common Causes of P0264 Audi
- Faulty Fuel Injector: The most common cause of a low voltage condition in the Cylinder 2 Injector Circuit is a defective fuel injector that is not operating correctly.
- Wiring Issues: Damaged or corroded wiring connections leading to the fuel injector can disrupt the electrical signal and cause low voltage readings.
- PCM Malfunction: A problem with the powertrain control module (PCM) responsible for regulating the injector circuit could lead to voltage irregularities.
- Poor Electrical Connection: Loose or poor connections at the injector or PCM can result in insufficient power supply to the injector.
- Injector Control Circuit Malfunction: Issues with the control circuitry that governs the injector's operation can also trigger this code.
Symptoms of P0264 Audi
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Engine Misfires: A decrease in engine performance, such as rough idling, hesitation, or misfires, can occur due to improper fuel delivery to Cylinder 2.
- Decreased Fuel Efficiency: A drop in fuel efficiency may be noticed as the engine compensates for the inadequate fuel supply to one cylinder.
- Engine Stalling: In severe cases, the engine may stall or struggle to maintain a consistent idle due to the injector circuit issue.
- Increased Emissions: A malfunctioning injector can lead to increased emissions output, potentially causing the vehicle to fail emissions tests.
How to Fix P0264 Audi
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific DTC and pinpoint the problem area within the Cylinder 2 Injector Circuit.
- Inspect Wiring and Connections: Check the wiring harness and connections leading to the fuel injector for any signs of damage, corrosion, or loose connections.
- Test Fuel Injector: Test the functionality of the fuel injector in Cylinder 2 to determine if it is operating correctly and delivering the proper amount of fuel.
- Replace Faulty Components: If the fuel injector, wiring, or PCM is found to be faulty, replace the defective components with new ones to restore proper operation.
- Clear Codes and Test Drive: After completing the repair, clear the DTCs from the PCM memory, and test drive the vehicle to ensure that the issue has been resolved.
Cost to Fix P0264 Audi
The cost estimate for addressing a Cylinder 2 Injector Circuit Low issue in an Audi vehicle can vary depending on the specific cause of the problem and the parts/labour required for the repair. On average, the parts cost for a new fuel injector can range from $150 to $300, while the labour cost for the repair process may fall between $150 to $300. Additional costs for diagnostic time, potential wiring repairs, or PCM replacement could increase the overall repair expenses.
