I recall the change happened in 1995 Model year: A4, A6, and A8.

I don't recall.

ABS is combined with EBV (electronic brake proportioning valve), which
allows for each of the wheels to be separately controlled as opposed to the
old mechanical brake proportioning valve. Also the Mk5 Bosch ABS can
include such as EDS (EDL in some markets), and ASR. The new system can be
diagnosed with the VAG 1551 and VAG 1552 tools. Much more detail
differences, this is what I recall off the cuff.
