Code P1497 Audi Description
The P1497 code for Audi vehicles indicates a Secondary Air System Bank 3 Flow Fault. This fault occurs when there is a problem with the flow of air in the secondary air system, specifically in bank 3 of the engine. The secondary air system is responsible for reducing harmful emissions by injecting fresh air into the exhaust system to help burn off any remaining fuel. When this system fails, it can lead to increased emissions and poor engine performance.
