These will put all of this crap to rest.
Thank you and have a nice day.
Gee golly, I hate to put more fuel on this fire, but the only exterior pictures of your car that you've posted are from 1)a dealership and 2)a public parking lot, with the car in a "Reserved" spot (where it probably is parked every single day). However, you did not post an exterior shot of the car from inside your garage last night.
More to that point, the interior... I don't trust interior shots on manufacturer's websites, since they tend to post European models, pre-production models, etc, which don't necessarily match what ends up in the U.S. So, I went to a local dealership's website, and pulled up a 2012 S4 from their inventory:
Here's yours (I lightened it up so it's easier to see some details):
A few differences between the two that I noticed:
-The center/spoke proportions on the steering wheels are different
-The dealer's S4 has a light-colored trim piece surrounding the steering wheel buttons (2012 A4's also have this)
-The speedometer markings are spaced and oriented differently
-The tachometer markings are spaced differently
-The space between the speedo and tach is different
-Yours has a small, circular gauge in the lower right corner of the instrument cluster. Such a gauge does not appear to fit in the cluster of the dealer's S4.
The dealership's S4 is the "Premium Plus" trim level. There is a higher trim level--"Prestige"--and maybe this is what you have? Of course, I'd be shocked if Audi put different instrument clusters in the two different trims, and that the "upscale" one would have fewer detailed "touches", and appear to be from the 2004-2008 era.
And in case you're wondering, yes, I do have too much time on my hands, and no, I don't have anything better to do right now.
