Audi Secondary Air Injection Solenoid Replacement

Audi Secondary Air Injection Solenoid

The secondary air injection solenoid in your Audi plays a key role in regulating airflow to the exhaust system during cold starts. It opens and closes the secondary air valve to help reduce emissions quickly. If it fails, it can cause increased exhaust emissions and trouble codes.

Why the Secondary Air Injection Solenoid Matters

Essential for timed control of air flow into the exhaust stream.

• Optimizes Cold Start Emissions: Helps reduce hydrocarbons during engine warm-up.
• Improves System Efficiency: Coordinates with the ECU for precise air injection timing.
• Supports Catalytic Converter Function: Assists in rapid light-off of the catalyst.
• Prevents Emissions-Related Faults: Reduces risk of check engine light activation.
