    Will a ECU from 2000 2.8 work in a 1998 2.8?

    Hello experts,

    I'm having issues with my 1998 2.8 30 valve auto. I'm thinking at this point I have a bad, over heating ECU. A local yard has a 2000 A4 2.8 auto FWD with a ECU.

    Mine is 4D0 907 551 H

    2000 is 3B0 907 551 AN

    I believe the 2000 A4 is also a FWD, the same as mine. Both are auto's too. Does anyone know if it will work in my older car?

    Many thanks..

    Paul

    One is ME7.1 DBW, the other is M5.92 DBC. Not interchangeable.

    98-99 Passat, a4, or a6 DBC (AHA engine) will all work.

    Good news is the ecu you need is relatively cheap. If you need one, Shoot me a PM. I have a couple.
