Interpreting Audi's order system

[Gary Erickson]

Morning all,

Recently my father placed an order for a 2001 A6 2.7t to be delivered
sometime in March or early April.

The dealer (Carrera in Bend, OR) has been doing a great job of keeping
him posted via email, and last night sent along a scan of the car's
current status.  (May be seen at

It's yet to be built, so there's not much information there other than
the specifics of the order.  Under the options heading, the following
list occurs:

PAW 
PFX
PPL
PST  <-- Sport Pkg w/17" BBS wheels -- Go Dad!
QTR
WM2  <-- Anyone recognize this one?
3Y5

He thinks he's got most of the list translated to the corresponding
options that he ordered, but can't quite figure out what "WM2" might be?

Anybody familiar with Audi's ordering codes (or who ordered a car with
that option) able to shed any light?

TIA!
