    I wonder what they used to reprogram the ECU?

    I wonder if it was some sort of home-made equipment? Or one of those handheld programmers? HPTuners' new MPVI II now has Audi support but I highly, highly doubt that is the one they used as that is very new.

    Or probably one of the other diagnostic tools that we don't talk about on here

    I would not know, vcds straight from Ross Tech being my first experience programming anything on an import

    I do have an HP tuners mpvi unit BTW.... I just figured it made more sense to purchase the hex-v2 since it has such a track record and is similar to the factory tools.

    No.

    And exactly what you need depends on what methods were used to install the FOD to begin with. Back when that car was new, some tuners were still soldering in new chips, some even with piggy-back boards, and after that some who just flashed put countermeasures in their code to make it impossible to update the ECU without their proprietary tools.

    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.

    I googled "09D927750FH" and found out that is the transmission control module?

    I then googled "4L0910560C" and found that is the engine computer?



    but what do the "Calibration Verification Number" mean?

    Think of them as a fingerprint or hash or checksum of the software in that module.

    How to I find out what method was used and what I need?

    The safety screws on the ECU looked as if they had never been touched, so I am doubtful that anything was modified on that computer module physically.

    Hopefully it hasnt been locked because of propriety tools designed to prevent tampering.

    I hope I can get this figured out!

    Ah that is what I figured. I am familiar with those on the american domestic vehicles I have tuned.
