Description

This listing is for a reconditioned Garrett GT17V turbocharger, suitable for the Toyota Avensis 2.0 D-4D (1AD-FTV engine, 126 HP) manufactured between 2006 and 2010. This unit is a direct replacement for original equipment part numbers 727210-5001s and 172010G01C, offering a cost-effective solution for turbocharger replacement.

The Garrett GT17V is a variable nozzle turbine (VNT) turbocharger, known for its ability to optimise boost pressure across a wide RPM range for improved engine response and fuel efficiency. Common failure modes for this specific application often involve the variable vane mechanism seizing due to carbon and soot build-up from exhaust gases. This can lead to over-boosting or under-boosting, resulting in reduced engine performance, ‘limp mode’ activation, or excessive smoke from the exhaust. Electronic actuator faults are also prevalent with this series, preventing proper control of the VNT mechanism even if the vanes are free, leading to similar performance issues. Additionally, like many turbochargers, wear to the compressor and turbine shaft bearings (CHRA) can occur. This is typically caused by issues such as oil starvation, contamination of the lubrication system, or excessive heat. Symptoms of CHRA wear include excessive shaft play, oil leaks into the exhaust or intake system, or a distinct high-pitched whining noise under acceleration.

What this turbocharger fits

This reconditioned GT17V turbocharger is specifically designed for the Toyota Avensis 2.0 D-4D diesel engine, identified by the 1AD-FTV engine code, producing 126 horsepower. It covers vehicles produced from 2006 to 2010. To ensure correct fitment, it is crucial to cross-reference your existing turbocharger’s part number with OE number 727210-5001s or its alternative, 172010G01C. This unit is a critical component for maintaining the specified performance, fuel economy, and emissions compliance of your Avensis.

At Gap Turbos, we specialise in providing high-quality turbocharger solutions. This reconditioned unit has undergone a meticulous process, including full disassembly, thorough inspection of all components, comprehensive cleaning, and the replacement of all worn parts with new, high-quality equivalents. The core assembly (CHRA) is then balanced to exacting OEM specifications using advanced VSR (Vibration Sorting Rig) machinery to ensure optimal longevity and performance. Finally, the variable geometry mechanism is calibrated and tested for correct operation. We also offer new exchange units for certain models, and our Birmingham workshop provides professional fitting and pre-installation cleaning services for associated pipework and intercoolers. All our reconditioned turbochargers come with a comprehensive warranty.

Specifications

Vehicle fitment

• Toyota Avensis 2.0 D-4D

Common faults & troubleshooting

• Reduced engine power or ‘limp mode’: Often indicates a seized variable vane mechanism or a faulty electronic actuator, preventing correct boost control.
• Excessive black smoke from exhaust: Can be a sign of the turbocharger not providing enough boost, leading to incomplete combustion of fuel.
• High-pitched whining or siren-like noise under acceleration: Suggests wear to the turbocharger’s internal bearings (CHRA), indicating excessive shaft play.
• Blue/white smoke from exhaust or oil consumption: Points to oil leaking past worn turbocharger seals into the exhaust or intake system.
• Check engine light (CEL) with boost-related fault codes (e.g., P0234): Confirms an issue with the turbocharger’s boost pressure regulation, likely the VNT or actuator.

Fitting notes for this unit

• Oil Feed Line: Always replace the turbocharger oil feed pipe and banjo bolts. These lines are prone to carbon build-up, restricting oil flow and causing premature turbo failure.
• Oil Drain: Ensure the oil drain pipe is clear and free from obstructions. A blocked drain can cause oil to back up in the CHRA, leading to seal failure.
• Intercooler and Pipework: Thoroughly clean the intercooler and all associated intake pipework to remove any debris, metal fragments, or oil residue from the previous turbo failure.
• Engine Oil & Filter: Use new, manufacturer-specified engine oil and a new oil filter. Prime the oil system before starting the engine to ensure immediate lubrication to the new turbocharger.
• Gaskets: Always use new gaskets for the exhaust manifold, downpipe, and oil lines. Do not reuse old gaskets to prevent leaks.
• Actuator Calibration: If the turbocharger comes with a new electronic actuator, ensure it is correctly calibrated to the vehicle’s ECU using appropriate diagnostic tools after installation.
