    Please post a complete Auto-Scan for better context. Posting just fault codes without seeing what ECU they are in, connected to which engine, and installed in what car is almost pointless.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.
