- Some 2001 cars came with Bosch MAFs (and presumably A-Box ECUs).
- There is some confusion with cars near the 09/00 build mark (none verified)
- Some are 2001, some are 2001.5
- Some 2001.5 came with H-boxes and do not appear to have F-hoses
- Some 2001.5 are reported to have mismatching wheel/trunk badges
- Andy Whittaker's UK 1999 S4 seems to have a C box.
- The L and AA box information may be incorrect. Please mail me or post a comment in the talk section.
