Primary Vehicle Compatibility
This OM651.955 Biturbo engine is specific to top-tier performance and 4×4 variants. Accurate VIN verification is ABSOLUTELY CRITICAL.
Target Applications (Model years circa 2014-2018):
Mercedes-Benz Vito (W447) 4×4 (4MATIC) models with higher output
Mercedes-Benz Vito (W447) Sport Edition models
Mercedes-Benz V-Class (W447) 250 d (High-Power Variant)

What’s Included & Condition Notes
This is a complete, ultra-low-mileage long block sold as removed. Includes the engine block, cylinder head, crankshaft, pistons, valvetrain, oil pan, valve covers, and timing case. The defining Biturbo components (both turbochargers, associated manifolds, and piping) may or may not be included; this MUST be confirmed with the seller via photographs. The extremely low mileage indicates negligible wear. Sold untested unless specified.
Critical Installation & Buyer Advisory
Expert-Level Installation & Explicit Verification Required.
Biturbo System: Confirm if both turbos, intercooler, and all vacuum/actuator lines are included. If not, your original components must be in excellent condition for transfer.
Ancillaries NOT Included (Typical): Fuel system (injectors, high-pressure pump), complete engine wiring harness, all sensors, ECU, alternator, A/C compressor, starter, and engine mounts.
Electronic Integration is Non-Negotiable: The vehicle’s original ECU MUST be used and will require extensive coding/adaptation via Mercedes-Benz XENTRY to match the new engine’s hardware. This process is complex and dealership-level.
Mandatory Pre-Purchase Action: Contact seller before any commitment. You must:
Provide your full VIN for exact compatibility check.
Request and scrutinize detailed, current photographs of the complete engine, focusing on the turbocharger assembly.
Confirm the precise list of included components.
