A genuine Audi secondary air pump hose (OEM 04E131149B) is now available as a used replacement. Also called a secondary air injection line, this part routes air from the pump to the exhaust manifold during cold starts to reduce emissions. It fits the 1.4L TFSI gasoline engine and the 1.4L plug-in hybrid (PHEV) in the A3 and A3 Sportback e-tron. Over time, the hose can dry and crack, leading to a check-engine light or a failed emissions monitor.
