Important Buyer Notes & Requirements

 Professional Installation & Verification Still Required.

• Condition: Sold as a used, complete assembly. A pre-purchase inspection of critical items (turbo shaft play, injector seal surfaces) is advised.

• Components YOU Must Still Provide/Transfer:

  • Engine Control Unit (ECU) and complete engine wiring harness.

  • Starter Motor, A/C compressor, and engine mounts.

  • Any emission components (DPF, EGR valve) not visibly attached.

  • All coolant hoses, pipes, and intercooler.

• Electronic Integration: The vehicle’s original ECU must be used and will require adaptation via Mercedes-Benz diagnostic systems (e.g., DAS/XENTRY).

• VIN Verification: Contact seller to confirm compatibility using your VIN, as variations exist within the OM646 family for different power outputs and emissions standards.
