What?!? You doubt my figures? Most of the info on this page is directly from Audi (and we know they NEVER document anything wrong, do they?).
- 1990 Coupe Quattro "AT A GLANCE" media information
- 1990 Coupe Quattro technical specifications
- 1991 Coupe Quattro "AT A GLANCE" media information

Have you found the sticker in the trunk with the feature and color codes? Now you can decipher them by checking out these tables from the parts fiche.
- Airbag added beginning with Coupe chassis #1109, and Sedan chassis ????. Non-airbag cars have a package shelf in front of the driver's knees.
- Sway bars changed from just a front, to front and rear, starting with Coupe chassis #3682, Sedan chassis ????.
- Various hydraulic system parts changed, starting with Coupe chassis #6901, Sedan chassis ???? (October '89 build). They changed again for the '91 model year. (see hydraulic steering pump)
- Tubular stainless steel exhaust header changed to a cast iron manifold starting with Coupe chassis #13611 (March '90 build), Sedan chassis ????.
- ECU changed P/N, starting with Coupe chassis #15001 (March '90 build), Sedan chassis ????. The older ECU uses the simple VAG 1115 diagnostic tool (that you build with a diode), the newer one supposedly requires the expensive VAG 1551, but I believe that 1115 will still work (instructions coming soon).
- The sunroof changed from steel to smoked glass for 1991 model year (Coupe only?).

#* The parts fiche says that the letter for the CoupeQ should be "K", but all of the ones I know of are "G".
** I don't know what the differences between the "D" and "E" engine designations are, but the "D" engines are found in the early Coupes (presumably the early 90s too, but I haven't found an early example). The change took place sometime during the July 1989 build dates. However, the "7A" engine identification is used for both versions.
