Critical Buyer Advisory & Installation Notes

⚠️ 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.
Ancillaries NOT Included (Typically): Engine Control Module (ECU), turbocharger, fuel injectors, high-pressure pump, alternator, A/C compressor, starter motor, wiring harness, sensors (unless mounted on block), and exhaust manifolds. Confirm exact contents via provided photos.
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.
