What is the p0411 code for secondary air injection?
The PCM monitors the secondary air injection system for faults. If it detects a problem, it turns on the check engine light and triggers a P0411 code. It’s worth noting that not all vehicles have a secondary air injection system. Users have reported P0411 for the following makes: Volkswagen (especially on a VW Jetta), Chevrolet, BMW, GMC, and Audi.

Can a p0411 leak cause an Audi A4 to break down?
An exhaust leak can cause the ECM to think that the AIR system is not working right. Look for damage to the exhaust system. If there’s a leak, you should be able to hear it. P0411 in the Audi A4 is not likely to cause the vehicle to break down, but can affect drivability.

What is the error code for secondary air injection?
Inspect the steel line that connects to the exhaust catalyst for any damages or holes that could send false information, include the exhaust ports in your inspection. Other related secondary air injection system error codes include P0410, P0412, P0491, and P0492.
What is the diagnostic code for secondary air injection?
Cost of diagnosing the P0411 code. P0411 is a diagnostic trouble code (DTC) for “Secondary Air Injection System Incorrect Flow Detected”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
