    Do you have a scan showing the fault codes (VCDS saves all the auto-scans in C:\Ross-Tech\VCDS\Scans) as that would give more clues?

    "Too lean" is either air unmetered getting into the engine somehow, or not enough fuel.

    But I don't know this engine or the SIMOS management it has on it.

    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.
