Description
This is a reconditioned BorgWarner BV43 turbocharger, specifically engineered for the Audi A6 2.0 TDI, 140 HP models manufactured between 2004 and 2008. It is a direct replacement for units with OE part number 53039880109 or alternative 03G145702H, ensuring precise fitment and restored performance for your diesel engine.
Common failure modes for this particular turbocharger often involve the oil seals, leading to characteristic blue smoke emissions from the exhaust as engine oil enters the exhaust system. Another frequent issue is wheel imbalance, which can result in excessive noise, reduced performance, and ultimately catastrophic turbocharger failure if not addressed promptly. These issues typically stem from prolonged use, inadequate lubrication, or foreign object damage.
At Gap Turbos, we specialise in providing high-quality solutions for these common problems. Our reconditioned units undergo a rigorous remanufacturing process where all worn components are replaced with new, high-specification parts, and the unit is balanced to OE standards. We also offer a new exchange service for customers requiring a brand new unit. For those local to our Birmingham facility, we provide a professional fitting service, which includes a thorough inspection of the vehicle’s ancillary systems and a full clean of the intercooler and associated pipework to prevent future contamination. We meticulously check oil feed lines and breathers to ensure optimal conditions for the new or reconditioned turbocharger.

Common faults & troubleshooting
[‘* Blue Smoke from Exhaust: Often indicates worn oil seals within the turbocharger, allowing engine oil to enter the exhaust system. This unit likely requires reconditioning or replacement.’, ‘* Excessive Turbo Whine/Screech: Can point to damaged compressor or turbine wheels, or worn bearings due to imbalance. Inspect for foreign object damage or shaft play.’, ‘* Loss of Power/Limp Mode: Could be due to a seized variable geometry mechanism or a boost leak. Check actuator movement and all boost pipe connections.’, ‘* Oil Leaks around Turbocharger: Verify the oil feed and return lines for blockages or loose connections, as internal turbo seals may also be failing.’, ‘* Engine Management Light (EML) with Boost Fault Codes: Often caused by incorrect boost pressure, which can stem from a faulty turbocharger, wastegate actuator, or boost sensor.’]
Fitting notes for this unit
[‘* Oil Prime: Crucially, before starting the engine, manually prime the turbocharger with clean engine oil through the oil feed hole to prevent dry running on initial start-up.’, ‘* New Gaskets & Seals: Always fit a complete new set of gaskets and seals, especially for the oil feed and return lines, to prevent leaks and ensure proper sealing.’, “* Clean Oil Feed Pipe: Inspect and thoroughly clean or replace the turbocharger’s oil feed pipe to ensure unrestricted oil flow and prevent carbon deposits from recirculating.”, ‘* Intercooler & Pipework Clean: Flush the intercooler and all associated boost pipes to remove any oil residue or debris from the previous turbo failure, which could contaminate the new unit.’, “* Check Breather System: Verify that the engine’s breather system (PCV valve and associated pipes) is clear and functioning correctly, as blockages can lead to excessive crankcase pressure and oil seal leaks.”]

Need this turbo cleaned or reconditioned?
Many turbo faults are actuator-only or VNT vane carbon buildup, not a failed core. We strip, ultrasonically clean, rebuild, and balance to OEM tolerances with a 24-month parts and labour warranty.
