Description

This is a reconditioned Garrett GT17V turbocharger for the Ford Focus 1.8 TDCi (115hp) models produced between 2005 and 2010. Our service provides a cost-effective, reliable replacement for a failed original unit, rebuilt to OEM specifications in our Birmingham workshop.

The GT17V is a variable nozzle turbine (VNT) turbocharger, also known as a variable geometry turbo (VGT). This technology uses adjustable vanes to control exhaust gas flow over the turbine wheel, allowing for improved throttle response and efficiency across a wide range of engine speeds. It is a common unit found on many mid-sized diesel engines of this era, known for its balance of performance and fuel economy. However, the complexity of the VNT mechanism can also be a point of failure, particularly on vehicles used for frequent short journeys.

Common failure modes for this specific 742110-5007s unit are well-documented. The most frequent issue we see is the seizure of the VNT mechanism due to carbon (soot) build-up. This prevents the vanes from adjusting correctly, leading to either underboost or overboost conditions and triggering the engine management light. Another common fault is with the electronic actuator that controls the vane position. Internally, failure of the main shaft bearings within the central housing rotating assembly (CHRA) can occur due to oil contamination or starvation, resulting in excessive play, noise, and eventual catastrophic failure.

What this turbocharger fits

This reconditioned turbocharger is a direct replacement for the original Ford/Garrett unit on the 1.8 TDCi engine. It is specifically intended for the 115hp variants with engine codes KKDA and KKDB. These engines were fitted to the Ford Focus Mk2 and C-Max models manufactured from approximately 2005 to 2010. To ensure correct fitment, it is essential to match the part number from your original turbo. The primary OE part number is 742110-5007s, but you may also find alternative numbers such as 4M5Q6K682AG stamped on the unit’s identification plate.

At Gap Turbos, we offer several options. This listing is for a reconditioned unit, where we completely strip, clean, and inspect the original turbo. Worn or failed components, such as the bearing assembly, seals, and VNT mechanism, are replaced with new parts before the unit is balanced and calibrated on our specialist equipment. We can also supply brand new exchange units. For local customers, we provide a full fitting service at our Birmingham workshop, which includes changing the engine oil and filter, and replacing the oil feed pipe. We also strongly recommend and can perform intake system and DPF cleaning to prevent a repeat failure of the new unit.

All our reconditioned turbochargers come with a standard warranty. Please contact us with your vehicle registration or original part number for a precise quote and to confirm availability.

Specifications

Vehicle fitment

• Ford Focus 1.8 TDCi

Common faults & troubleshooting

• Significant loss of power: Often caused by a seized VNT (variable nozzle turbine) mechanism due to carbon build-up, preventing the turbo from creating sufficient boost.
• Black smoke from the exhaust: This indicates over-fuelling, a common symptom when the turbo is not providing the correct amount of air to the engine.
• Limp mode or engine management light: The ECU will detect an overboost or underboost condition from a faulty VNT mechanism or a failed electronic actuator, triggering a fault code.
• High-pitched whistling or siren noise: This sound, which changes with engine speed, points to a damaged compressor wheel, often from contact with the housing due to bearing wear.
• Blue smoke and high oil consumption: This is a clear sign that the turbo’s internal oil seals have failed, allowing engine oil to be burned in the intake or exhaust.

Fitting notes for this unit

• Change engine oil and filter: Always use the manufacturer-specified grade of fully synthetic oil to ensure correct lubrication and prevent premature failure.
• Replace the oil feed pipe: The original pipe can become restricted with carbonised oil. Failure to replace it is a primary cause of repeat turbo failure and will invalidate the warranty.
• Prime the new turbo: Before starting the engine, use a syringe to inject clean engine oil into the turbo’s oil feed port to ensure the bearings are lubricated on first start-up.
• Check oil drain pipe for blockages: Ensure the oil drain pipe returning to the sump is completely clear of sludge or obstructions to prevent oil backing up into the turbo housing.
• Clean the intake system: Thoroughly clean the intercooler, EGR valve, and all boost pipes to remove any oil residue or debris from the previous turbo failure.
• Torque all fixings correctly: Pay close attention to the manufacturer’s torque specifications for the exhaust manifold nuts and oil feed banjo bolts to prevent leaks or damage.
