Description

This reconditioned Garrett GT17V turbocharger is a direct replacement for the Audi A3 1.9 TDI (BXE/BLS engine codes, 105 HP) manufactured between 2003 and 2010. It addresses common issues associated with the original unit, restoring performance and efficiency to your vehicle. As Birmingham’s turbocharger specialists since 1986, Gap Turbos ensures each reconditioned unit meets stringent quality standards, providing a cost-effective and reliable solution.

The GT17V series, known for its Variable Nozzle Turbine (VNT) technology, is a popular choice for these diesel engines, offering responsive power delivery across the rev range. However, over time, these turbos can experience specific failure modes that compromise engine performance and fuel economy. The most common issues we encounter include seizure of the VNT mechanism due to carbon build-up and soot accumulation, particularly prevalent in stop-start driving conditions. This seizure can lead to either persistent over-boosting, causing limp mode, or under-boosting, resulting in a noticeable lack of power. Electronic actuator faults are also prevalent, often manifesting as incorrect vane operation and triggering engine management warning lights on the dashboard. Additionally, wear to the Compressor Housing Rotating Assembly (CHRA) bearings can occur, resulting in excessive shaft play, increased oil consumption, and characteristic whining or grinding noises emanating from the turbocharger itself.

At Gap Turbos, our meticulous reconditioning process for this 03G253016N / 713672-5006s unit involves a comprehensive strip-down, thorough inspection of all components, and the replacement of all worn parts with new, high-quality equivalents. This includes new bearings, thrust collars, seals, and a precision re-balanced CHRA to ensure smooth, long-lasting operation. The VNT mechanism is meticulously cleaned, de-carbonised, re-calibrated using specialist equipment, and rigorously tested to ensure optimal vane movement and boost control. We also offer new exchange units for customers requiring a quicker turnaround, full fitting services here at our dedicated workshop, and professional diagnostic cleaning of associated induction components and pipework to prevent recurring issues caused by residual contamination.

Specifications

Vehicle fitment

• Audi A3 1.9 TDI

Common faults & troubleshooting

• Loss of power or “limp mode”: Often indicates a seized VNT mechanism causing over-boost or under-boost, or a faulty electronic actuator.
• Whining or grinding noise from the engine bay: Typically signifies worn CHRA bearings or contact between the compressor/turbine wheels and their housings.
• Excessive blue/grey smoke from exhaust: Can be a sign of oil leaking past worn turbo seals into the exhaust or intake system.
• Engine management light (EML) illuminated with boost-related fault codes: Points to issues with boost pressure regulation, frequently due to actuator or VNT problems.
• Oil leaks around the turbocharger: Check for damaged oil feed/drain lines, loose connections, or failing turbo seals.

Fitting notes for this unit

• Always replace the oil feed pipe and drain gasket when fitting a new or reconditioned turbocharger to prevent oil starvation or leaks.
• Ensure the engine oil and oil filter are replaced with the correct specification prior to fitting, and prime the new turbo with clean engine oil through the oil feed port.
• Thoroughly clean all intercooler pipework and the intercooler itself to remove any residual oil or debris from the previous turbo failure.
• Torque all critical bolts, especially those on the exhaust manifold and oil lines, to the manufacturer’s specified settings to prevent leaks and ensure proper sealing.
• After installation, disconnect the fuel pump and crank the engine for 10-15 seconds to allow oil pressure to build and lubricate the turbocharger before initial start-up.
• Check for exhaust leaks and boost leaks after fitting; a small leak can significantly impact performance and turbo longevity.
