    Will this ECU work? One letter off.

    Hello, all,

    I want to buy a 2nd ECU for my Avant and have Oliver at SpeedTuningUSA flash it for me. My ECU has the number 4D0 907 551 AH, and I see this one at eBay:

    ...that has the number 4D0 907 551 H. Does the extra "A" in my number mean it won't work?

    Thanks :)

    I realized after posting this that I could just go to "the horse's mouth" as it were. I emailed Pignataro VW in Everett, WA (where I have the service done for my Avant, they are an authorized Audi Service Center with 4 Master Certified Audi techs on staff) and here is the reply I received:

    "So after doing a little digging it sound like the h code ecu supercedes to the ah. You should have no issues running this ecu.

    Thanks,
    Justin"

    Just FYI for y'all... :)
