If I was in the market for a 928, this is the first one I'd look at - well knowing that it is actually a 1991 S4:

Anybody know how I could tell at a glance that it was a 1991, and not a 1990?

Hilton

Leather handbrake?

Nicole

The handbrake is one way to tell (different shape and leather), but there is something much more obvious about this car that is only available on 91 and later models... and hard to retrofit.

Any guesses?

Here are a few things the 91 model has that are not visible on the pictures:

- more power assist in the steering (different pump and rack - if the rack has not been replaced with an incorrect one)
- re circulation function for the HVAC
- better sound insulation
- check engine light (instruments)
- improved alarm system
- improved under-hood light

Grey interior?

StratfordShark

Airbag? (I dont know when airbags arrived in US models - in UK not till GTS so MY92)

That thick insulation mat in hatch? My MY91 has it and previous MY88 I owned had much thinner material

Nicole

No, on the US models, airbags started in 1990. The mat in the hatch is aftermarket Lloyd.

What's the interior color of your Amazon Green 1991 model?

Leon Speed

Could it be:
-painted rear wing
-analog clock
-LH cover button
-cabin lights dimmer on the console face (and wiper interval wheel on the other side)?

Nicole

Sorry - None of the above.

Analog clock started in 1990
Painted rear wing started with GTS
Not sure what you mean by LH Cover Button
No change in Cabin Lights from 1990 to 1991

Driver's side knee bolsters rather than a shelf? (not sure if that's the correct term)

Nicole

Knee bolster came with airbags, starting in 1990 (in the US).

Niles

The third switch on the driver's seat does not look like the lumbar control on mine.

MFranke

The defroster vents have the inserts/covers to help prevent cracking of dash - Is that it?

Gary Knox

Location of the mirror switch?? (never owned a '90 or '91, but as I recall, this is certainly different location than my '89 and other S4's where it was up by the seat memory buttons).

Bertrand Daoust

Improved door seals.
Cooling flaps in front of radiator eliminated.

I'm going to go out on a limb (and not a thin limb because I just checked two '91s I have in my garage at the moment to be sure) that this car is indeed a '90 and not a '91.

There is something present in the pictures that would not be on a '91 that indicates the presence of a system that no one in their right mind would retro-fit to a '91.

Hint: do not look for it in interior pictures.

Edit: Although I am open to the possibility that this car is a very early '91 and used a few stray '90 bits still lying around the factory floor.
