Audi Secondary Air Injection Relay Replacement

Audi Secondary Air Injection Relay

The secondary air injection relay controls the electric air pump in your Audi’s emissions system. This relay activates the pump during cold starts to help reduce unburned fuel in the exhaust and speed up catalyst warm-up. A failed relay can cause check engine lights, emissions test failures and reduced performance.
