Purpose and function in the supercharging system

The turbocharger oil line is responsible for transporting engine oil at the correct pressure to the turbine bearings. In the 2.0 TDI CFHD engines, this is crucial for:

• maintaining a stable oil film on the rotor and bearings,
• reducing friction and overheating of rotating elements,
• reducing the risk of turbocharger seizure under engine load,
• maintaining repeatable boost parameters in a diesel engine.

Selecting the correct oil line is particularly important in modern diesel engines, where the turbocharger operates at high engine speeds and elevated exhaust gas temperatures.

Original origin and product category

The offered component falls into the turbocharger and parts category, meaning it has been designed specifically for use in supercharging systems, taking into account Audi's design requirements. Its original origin translates into:

• correct geometry of connections and bent sections,
• appropriate inner diameter of the pipe,
• compatibility with factory mounting points in the Audi A1 8X,
• consistency with the operating parameters of the diesel engine.

Thanks to this, the hose works with the turbocharger and engine block without the need for modifications or adapters.

Technical condition and benefits of choosing a used item

The hose is offered in used condition, allowing for cost-effective repair of the supercharger system while maintaining the original manufacturer's specifications. In practice, this means:

• attractive cost-to-quality ratio compared to new substitutes,
• maintaining the factory fit for the turbocharger and engine,
• the ability to quickly replace a damaged or leaking hose.

A used oil hose is a good choice for both workshops and individual users who want to restore proper turbine lubrication without overextending their service budget.

The Importance of a Correct Oil Line in a Diesel Engine

In diesel engines, the turbocharger operates in demanding conditions, so a functioning oil line has a direct impact on:

• boost pressure stability across the full rev range,
• reducing oil leaks around the turbine and engine block,
• reducing the risk of oil entering the intake system,
• extending the life of the turbocharger and associated components.

Replacing the hose is particularly recommended when regenerating the turbine, if signs of corrosion appear on the old hose or if a leak is detected in the lubrication system.

Part selection by numbers and substantive support

The turbocharger oil line for the Audi A1 8X was designed with a specific engine variant in mind, so it's worth using the manufacturer's markings and vehicle data when making your selection.
