This used genuine OEM vacuum hose/line (part number 8W0201991AK) comes from a donor Audi. It's the factory vacuum line that connects to the turbocharger's wastegate actuator on 2.0L TFSI engines, including the MHEV mild-hybrid variant. A failing or cracked vacuum hose can cause boost leaks, resulting in a loss of power, poor throttle response, or a check engine light for underboost conditions.
