Critical Buyer & Swapper Advisory
 Verification and Planning are Essential.

Condition: Sold as a used, complete assembly. VANOS health, DISA valve integrity, and oil leak history should be assessed. A pre-purchase compression test report is highly valuable.

Swap Specifics: For non-native applications, you will need custom engine mounts, an adapted exhaust, possibly a different oil pan/sump, and detailed wiring integration. The included ECU may require immo-deletion or coding to work in a different chassis.

Direct Replacement: For a direct replacement, you must match the engine’s attachment points (e.g., E46 vs. E39 oil pans and engine mounts differ) and confirm the ECU is compatible with your vehicle’s immobilizer system.

Action Required: Contact seller before purchase. You must:

Confirm the exact donor vehicle (chassis) this engine was removed from.

Obtain a complete list of included components with photos.

For swaps, research the specific adapter parts needed for your target chassis.
