 Professional Installation & Pre-Purchase Verification Mandatory.

Condition & Testing: Sold as-is, untested, in “as-removed” condition. A professional inspection prior to purchase or upon receipt is strongly recommended.

Core Component: Ideal for use as a direct replacement core or for a professional rebuild. All ancillary components from your original engine must be transferred.

Electronic Integration: The original ECU from the recipient vehicle must be used and will likely require adaptation coding via Mercedes-Benz diagnostic systems (XENTRY/DAS) for proper operation.

VIN Verification is REQUIRED: Contact us before ordering. You must provide your vehicle’s VIN and original engine number to confirm compatibility of engine mounts, auxiliary drive, sensor types, and emission control hardware.
