Description

This listing is for a reconditioned BorgWarner BV39 turbocharger, specifically designed for the Audi A3 1.9 TDI, covering engine codes BKC and BLS, with 105 horsepower, manufactured between 2003 and 2009. This unit, with OE part number 54399880022 and alternative 03G253014G, offers a cost-effective and reliable solution to restore your vehicle’s performance and efficiency.

As Birmingham-based turbocharger specialists since 1986, Gap Turbos meticulously reconditions these BV39 units to meet or exceed original equipment specifications. The BorgWarner BV-series, common in VAG group fitments, often experiences common failure modes such as oil seal leaks, which typically manifest as excessive blue smoke from the exhaust, indicating oil bypassing the seals into the exhaust system. Another frequent issue is compressor or turbine wheel imbalance, often leading to reduced boost pressure, a noticeable loss of power, and audible whining or screeching noises from the turbocharger itself. These failures are frequently linked to inadequate lubrication, contaminated engine oil, or foreign object ingestion.

What this turbocharger fits

This reconditioned BV39 turbocharger is a direct fit for:

• Vehicle: Audi A3
• Engine Codes: BKC, BLS
• Horsepower: 105 HP

• Original Equipment (OE) Part Number: 54399880022
• Alternative Part Number: 03G253014G

Our comprehensive reconditioning process for this BV39 unit involves full disassembly, thorough cleaning of all components, and meticulous inspection for wear or damage. All critical wear parts, including bearings, seals, and thrust components, are replaced with new, high-quality equivalents. The rotating assembly undergoes precision balancing to ensure optimal performance and longevity, critical for preventing future wheel imbalance issues. Beyond reconditioned units, we also offer new exchange units for a quicker turnaround, a professional fitting service at our Birmingham workshop, and full system cleaning.

Common faults & troubleshooting

[“Loss of power or engine in ‘limp mode’: This often indicates a boost leak, a faulty N75 boost control valve, or a stuck VNT mechanism within the turbocharger.”, ‘Excessive blue smoke from the exhaust: This is a strong indicator of failed oil seals within the turbocharger, allowing oil to enter the exhaust system.’, ‘Whining, screeching, or grinding noises from the engine bay: These sounds often suggest damage or severe imbalance to the compressor or turbine wheels, or worn bearings.’, ‘Visible oil leaks around the turbocharger housing: Inspect the oil feed and drain lines for blockages, cracks, or loose connections, as well as the turbocharger seals themselves.’, ‘Increased engine oil consumption without visible leaks: This symptom frequently points to internal turbocharger oil seal failure, where oil is burnt off in the combustion or exhaust process.’]

Fitting notes for this unit

[‘Always replace the oil feed pipe and associated gaskets; blockages in the old pipe are a common cause of premature turbo failure.’, ‘Ensure the oil drain pipe is completely clear of carbon deposits or sludge to allow unrestricted oil flow back to the sump.’, ‘Pre-fill the turbocharger oil inlet with clean engine oil before fitting the oil feed pipe to ensure immediate lubrication upon first start-up.’, “Torque all exhaust manifold, downpipe, and oil line bolts to the manufacturer’s specified settings to prevent leaks and stress.”, ‘Allow the engine to idle for several minutes after fitting the new turbocharger before revving, to ensure the oil system is fully primed and circulating.’, ‘Thoroughly clean all associated pipework, the intercooler, and catalytic converter to remove any metal fragments, oil residue, or carbon deposits from the previous failure.’]
