    ECU Part Number?

    Hey all, I just picked up my spare ECU from a shop it had been sitting at for a while, and Google is failing me at the moment - is Bosch 8E0909518AK the right ECU for our RS6s?

    Thx,
    Steve

    I'm showing 4D1907558, 4D1907558A, 4D1907558B, and 4D1907558F. All should work but the new parts catalog shows all part #'s with an 'X' suffix added to the end which means remanufactured only available new.
    The one in my car is 4D1907558D which Audi is showing NLA.

    Hi Steve!

    8E0909518AK is totally wrong, it's a 4-banger ME7.5 ECU. Ours is ME7.1.1 and specific to the RS6. Part numbers above.

    Best,
    Alex-
