The Audi 5WA131128A Secondary Air Pump Hose / Line is a used genuine OEM part that also replaces 5WA131128. This air injection line delivers fresh air to the exhaust during cold starts to speed catalytic converter light-off. A cracked or leaking hose triggers a check engine light for insufficient secondary air flow. Designed for 2.0L turbocharged and mild-hybrid engines in the A3 lineup.
