The OEM Vacuum/Breather Hose (Part Number 1K0133778AF) is designed for precise integration within the crankcase ventilation system, primarily located in the engine bay of Audi A3 Quattro models from 2005 to 2009. Its primary function is to facilitate the proper flow of crankcase gases, preventing pressure build-up that can lead to oil leaks and engine inefficiency. This part connects vital components such as the crankcase to the intake manifold, ensuring optimal engine performance.
Common issues necessitating replacement include wear, cracking, or disconnection, which can lead to an increase in emissions and reduced engine efficiency. This part is also known as a crankcase breather line. Alternative part numbers include 1K0133778AK. Ensure your vehicle maintains its factory-original functionality with this authentic part sourced from salvage operations.
