    Post an Auto-Scan please so we can see exactly what ECU you have.

    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.

    Compare specified and actual MAF readings in MVB 003. If specified and actual MAF readings do not diverge much, then EGR is working as designed. If they do diverge substantially, then there is a problem with your EGR system.

    Log the actual MAF reading during a full-throttle run through second gear, from as low an RPM and you can to the engine's redline.

    It seems to me that you are trying to apply information/procedures that are specific to petrol-fueled engines to your diesel. Your diesel engine management system does not use the concept of fuel trim, and your ECU does have fuel trim data in MVB 032.

    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.
