Restore Mercedes-Benz Performance to Your C220 CDI W203 or W204 with a New Turbo Core (CHRA)! Is your Mercedes-Benz C220 CDI (W203 or W204 chassis, equipped with the OM646 engine) experiencing a noticeable loss of power, sluggish acceleration, increased fuel consumption, excessive black or blue exhaust smoke, or unusual, loud noises from the engine, especially a high-pitched whine or grinding sound? These are clear and critical indicators of a worn or damaged turbocharger core. Our high-quality Turbo Core (CHRA - Center Housing Rotating Assembly) provides a cost-effective and reliable solution to revitalize your turbo without the need for a complete replacement unit. The CHRA is the vital heart of your turbocharger. It contains the precision-machined compressor wheel, turbine wheel, and the robust bearing system that allows them to spin at immense speeds. Mercedes-Benz CDI engines, renowned for their smooth power delivery, impressive torque, and fuel efficiency, rely heavily on their turbochargers to provide the refined driving experience expected from a C-Class. Over time, due to the extreme temperatures, high rotational speeds, and demanding conditions, these internal components can degrade, leading to shaft play, oil leaks, and a significant loss in boost pressure. Replacing just the CHRA is a smart and economical choice when your turbocharger's external housings (compressor and turbine) are still in good, undamaged condition, offering substantial savings over a brand-new turbo. This approach is ideal for maintaining the premium driving dynamics and robust capabilities your Mercedes-Benz is known for, whether it's the elegant W203 or the modern W204 chassis. Why Choose Our Turbo Core? For Mercedes-Benz C220 CDI W203 and W204 owners, maintaining the turbocharger's health is key to enjoying the vehicle's luxurious driving experience, impressive fuel economy, and responsive performance. Our high-quality CHRA offers an excellent value proposition, allowing you to address internal turbo wear without the significant expense of a complete new turbo. By choosing to replace the turbo core, you effectively extend the life of your turbocharger and ensure your vehicle continues to deliver its expected dynamics and efficiency.

• Precision-Balanced for Optimal Performance: Each CHRA is rigorously tested and dynamically balanced to extremely tight tolerances. This ensures smooth, vibration-free operation at high RPMs, crucial for maximizing efficiency and extending the lifespan of the turbocharger in your C220 CDI (OM646 engine).
• Restores Full Engine Power & Torque: Directly replaces the worn internal components, bringing your turbocharger back to its factory specifications for efficient air compression and optimal boost pressure. This restores your vehicle's original power, torque, and outstanding fuel efficiency, essential for responsive acceleration and confident driving in both W203 and W204 models.
• Reduced Oil Consumption & Smoke: Equipped with new, high-grade bearings and seals, this CHRA effectively eliminates internal oil leaks, which are a common cause of blue/white exhaust smoke and excessive oil consumption in failing turbos.
• Durable & Robust Construction: Manufactured with premium-grade materials, including high-strength alloys for the wheels and a robust bearing system, designed to withstand the extreme temperatures and pressures inherent in modern diesel engines.
• Direct Fit Replacement (GTA1852VK Series): Engineered to perfectly match the OEM specifications of the GTA1852VK series turbocharger found in your Mercedes C220 CDI (OM646 engine), specifically for W203 and W204 chassis. This ensures seamless integration with your existing turbo housings and simplifies the rebuild process.
