Description

This reconditioned BorgWarner BV43 turbocharger is a direct replacement for the Audi A6 2.0 TDI (140 HP) models from 2004-2008, specifically for BRE and BLB engine codes. It addresses common issues associated with the original unit, restoring your vehicle’s performance and efficiency with a meticulously rebuilt component.

As a leading Birmingham specialist since 1986, Gap Turbos provides this BV43 series turbocharger as a professionally reconditioned exchange unit. This means we supply a fully rebuilt turbocharger in exchange for your old, failed core. Our reconditioning process involves a complete strip-down, thorough cleaning, inspection of all components, and replacement of worn parts with new, high-quality equivalents. The core assembly is then balanced to exacting standards, ensuring smooth operation and optimal performance, meeting or exceeding original equipment manufacturer specifications. This approach offers a cost-effective and environmentally friendly alternative to purchasing a brand-new turbo.

Typical failures for this BV43 unit on the Audi A6 2.0 TDI often involve oil seal leaks, which commonly manifest as excessive blue smoke from the exhaust, indicating significant oil consumption. Another frequent issue encountered is wheel imbalance. This can lead to noticeable noise, reduced boost pressure, and, if left unaddressed, can result in catastrophic failure of the compressor or turbine wheels. Additionally, carbon build-up within the variable geometry mechanism is a prevalent problem, causing the turbo to either over-boost or under-boost, triggering engine management light warnings and impacting drivability.

Specifications

Vehicle fitment

• Audi A6 2.0 TDI

Common faults & troubleshooting

• Excessive blue smoke from exhaust: Indicates oil is burning, likely due to worn oil seals within the turbocharger.
• Whining or screeching noise from engine bay: Often a sign of failing turbo bearings or contact between the compressor/turbine wheel and housing.
• Loss of power or ‘limp mode’: Can be caused by the turbo failing to produce adequate boost, possibly due to a seized variable geometry mechanism or boost leak.
• Engine management light illuminated with boost-related fault codes: Points to issues with boost pressure regulation, often linked to the turbo’s variable geometry or actuator.
• Excessive oil consumption without visible leaks: Oil is being burnt through the engine, frequently through compromised turbo oil seals.

Fitting notes for this unit

• Always replace the oil feed pipe and drain pipe gaskets to prevent oil leaks and ensure proper lubrication.
• Thoroughly clean the intercooler and all associated pipework to remove any debris or oil contamination from the previous turbo failure.
• Ensure the engine oil and oil filter are replaced with the correct specification prior to fitting the new turbocharger.
• Prime the new turbocharger with clean engine oil through the oil feed hole before starting the engine to ensure immediate lubrication.
• Torque all exhaust manifold and turbo mounting bolts to the manufacturer’s specified settings to prevent leaks and stress.
• Allow the engine to idle for several minutes after the first start to allow oil pressure to stabilise and thoroughly lubricate the new unit.
