Need 3 plug ecu for B6 5speed autozam....cant get a part#

[runey]

hi ive been searching all over for an ecu for my b6 5speed autozam..........i found a sticker on the old ecu with a part number tht was fairly worn...it looked something like b587 18881? last digit/letter is unknown.....evrywhere i look for a b587 ecu returns no result, can someone correct me on if this is the right #? or give me an idea of a compatible ecu.....
also it is DOHC and there are 3 plugs for the ecu
