Function Audi A8 D3 рестайлинг

Function

  1. In the cold start phase, the ECM - 3 - activates the Secondary Air Injection (AIR) pump - 1 - via the Secondary Air Injection (AIR) pump relay - 2 -. Air reaches the combination valves for Secondary Air Injection (AIR) - 4 - and - 8 -.
  2. The Secondary Air Injection (AIR) valve - 5 - is activated in parallel, which allows the vacuum to reach the combination valves for Secondary Air Injection (AIR) - 4 - and - 8 -. The appropriate combination valve for Secondary Air Injection (AIR) thereby opens the path for secondary air to the exhaust channels of the cylinder head.
