Purpose and function in the turbocharging system

The oil line hose/pipe is responsible for precisely delivering oil to the turbocharger-connected components of the 1.4 TSI CAVC petrol engine. Proper oil flow is crucial for:

• cooling and lubrication of turbine bearings,
• maintaining stable oil pressure in the system,
• reducing the risk of turbocharger seizure and overheating,
• maintaining appropriate dynamics of the drive unit.

Using a component from the turbocharger group and parts with parameters consistent with the factory ones allows maintaining the proper operating conditions of the entire supercharging system.

Original origin and compatibility

The oil line comes from Volkswagen, which means the geometry, diameters, and connections are consistent with the manufacturer's factory specifications. This ensures:

• fits the turbocharging system in the VW Touran 1T with the 1.4 TSI CAVC engine,
• enables installation without structural modifications,
• maintains the original oil route, minimizing the risk of collision with other components.

OEM markings and available interchangeable numbers allow for clear verification of compatibility with a specific vehicle configuration, which is particularly important when working with TSI petrol units.

Used condition and operational aspects

The item is offered in used condition, which means it has been disassembled and has been previously used in a vehicle. This type of part is an attractive solution for users who:

• are looking for an economical alternative to a new oil line,
• want to keep the original specification of the turbocharging system,
• plan to repair or recondition a turbocharger within a reasonable budget.

Standard workshop procedures are recommended during installation: checking the tightness of connections, correct cable routing and replacing consumables (e.g. seals) in accordance with the vehicle manufacturer's recommendations.

Benefits of using the original oil line

The use of an original oil line in the turbocharging system of a petrol engine brings a number of practical benefits:

• Factory fit – maintaining the original oil route and correct positioning relative to the turbocharger and engine block.
• Stable operating parameters – the appropriate diameter and cross-section of the pipe support the correct oil pressure at critical points in the system.
• Operational safety – reducing the risk of leaks, spills and turbine overheating, which translates into longer component life.
• Compatibility with the petrol system – the hose design is adapted to the operating characteristics of a petrol-powered unit, including temperatures and loads typical of TSI engines.
