I'm looking for a stock ecu for my 2000 audi S4.
It has a 2.7 twin turbo 6 speed standard transmission.
The numbers on my old ecu are
4B0 907 551 k
0 261 206 561
I was told that as long as it came from a 2000 - 2001 audi with a 2.7 twin turbo, it did not matter if the numbers matched.

Does anybody know if this is true?
I would hate to buy one and have it not work.

Thanks

 

The Audi S4 is absolutely new, high-performance action adaptation of the accepted Audi A4 sedan. Subtle exoteric appearance analyze the S4 from the A4, but the 2.7 liter five-valve biturbo V6 bearing 250 application sets the S4 apart. Audi's acclaimed quattro all-wheel-drive arrangement is very standard, forth with 6-speed chiral transmission, action suspension, and 17-inch Avus admixture wheels.
