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:

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

  2. Obtain a complete list of included components with photos.

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