New Bi-Turbocharger Replacment K04+BV39 – Mercedes OM651 2.2 CDI

Restore the massive torque and high-efficiency power of your Mercedes-Benz with this brand-new premium Bi-Turbocharger assembly. Specifically designed for the sophisticated OM651 twin-stage charging system, this unit provides the seamless transition between the high-pressure and low-pressure stages required for modern Sprinter and Vito/Viano applications.

Detailed Vehicle Compatibility & Power Output

This turbocharger assembly is a direct 1:1 replacement for the following models equipped with the OM651 DE 22 LA engine:

Technical Specifications & Cross-Reference

This complex assembly replaces multiple BorgWarner (KKK) stages used in the twin-turbo setup. Verify compatibility using these identification numbers:

Key Product Features

• 100% Brand New: Zero-mileage assembly. Unlike remanufactured units, this features a factory-new manifold, actuators, and both high/low-pressure turbo cores.
• Precision Stage Calibration: The bypass valves and actuators are factory-synced to ensure the correct handover point between the small and large turbos.
• VSR High-Speed Balancing: Both rotating assemblies are precision-balanced at high RPMs to ensure quiet operation and maximum bearing life under heavy commercial loads.
• Advanced Thermal Alloys: Constructed with high-nickel content materials to withstand the extreme temperatures found in Euro 5 and Euro 6 emission-controlled engines.

Critical Installation Requirements

The OM651 twin-turbo system is highly sensitive to lubrication and installation errors:

1. Mandatory Oil Feed Replacement: Always replace the oil supply lines. Carbon deposits in these lines are the leading cause of immediate failure in new OM651 turbos.
2. Prime Both Units: Ensure both the small and large turbochargers are pre-lubricated with clean engine oil before the first start.
3. Oil Specification: Use only Mercedes-Benz approved MB 229.51 / 229.52 low-SAPS synthetic oil.
4. Cooling System Check: Verify the cooling system is free of air locks, as these turbos rely on efficient thermal management to survive long highway hauls.
