Purpose and function of the turbo oil line

The turbo oil line for the Audi A3, Audi Q3, and Volkswagen Golf 1.5 TSI is responsible for supplying engine oil to the turbocharger. Proper lubrication of the turbine bearings reduces friction, stabilizes operating temperatures, and reduces the risk of rotor seizure.

Using a cable that meets factory specifications is crucial for:

• maintaining proper oil pressure in the turbocharging system,
• ensuring even lubrication of rotating elements,
• reducing leaks and turbocharger performance losses,
• maintaining stable operating characteristics of the 1.5 TSI engine.

OEM build and fitment to the 1.5 TSI engine

The hose is designed as an original Volkswagen part, ensuring compatibility with factory mounting points and oil flow parameters. This allows installation in the 1.5 TSI engines used in the Audi A3, Audi Q3, and Volkswagen Golf without the need for modifications.

Key design features of the turbo oil line:

• geometry adapted to the drive system of the Volkswagen Group platform,
• appropriately selected internal diameter for stable oil supply,
• factory-designed ends for serial connectors in the turbocharger and engine block.

Used condition and service aspects

This component is offered in used condition, allowing for cost-effective turbocharger repair while maintaining original build quality. A used turbo oil line is a good solution in situations where:

• the existing cable has been mechanically damaged or corroded,
• there are leaks in the area of the turbocharger oil supply,
• it is necessary to replace the cable preventively when replacing the turbine.

Oil line replacement is recommended after any major intervention in the turbocharging system to reduce the risk of oil contamination and extend the life of the turbocharger.

Application in Volkswagen turbochargers and parts

This product falls into the turbocharger and parts category, meaning it's a component that works directly with the turbine in the 1.5 TSI engine. A properly selected oil line affects:

• stability of turbocharger operation in the full load range,
• maintaining the proper bearing temperature,
• reducing the risk of failures caused by insufficient lubrication.
