boiling pt = 140degC or 284degF. aliphatic polyether-based, can be mixed
with DOT4, characteristics will be (linearly) in between DOT3/DOt4
parameters. Cheap, most widely used, eats paint, absorbs water easily, eats
natural rubber seals.
DOT4: Brake Fluid Grade - Min dry boiling pt=230degC or 446degreesF.  Min
wet boiling pt = 155degC or 311degreesF.  borate ester based, can be mixed
with DOT3, characteristics will be (linearly) in between DOT3/DOT4
parameters, 50% more expensive than DOT3, eats paint,  significantly
increased resistance to moisture absorption compared to DOT3 (but still
absorbs water), does not eat natural rubber seals.
DOT5.1: Brake Fluid Grade - Min dry boiling pt=260degC or 500degF.  Min wet
boiling pt = 180degC or 356degF. It's a stupid name (5.x) as it's
glycol-based (borate ester) like DOT3/4 and has NO silicone.  Absorbs
water, eats paint, more expensive than DOT4, difficult to locate.
DOT5: Brake Fluid Grade - Min dry boiling pt=260degC or 500degF.  Min wet
boiling pt = 180degC or 356degF. Cannot mix with other fluids as it
contains silicone, turns to jelly if done so; colored purple. Used mostly
for antique cars and some motorcycles because it does not damage paint and
does not absorb water (it allows water to pool in the low pars of the
braking system).  Is more compressible than DOT3/4 though.  Twice as
expensive as DOT4 (and thus 3 times as expensive as DOT3) and has limited

Mr. Bentley: Publisher of the best shop manuals for Audis, he sadistically
removes seemingly non-pertinent information from the manuals (when doing
this, he's a genius, see above) that is highly pertinent.  This information
can then only be imparted from an Audi-certified technician under a full
moon whilst inebriated and concurrently undergoing secret fraternity
initiation rites.  Or by asking here on the list (booze may be required at
a later date, however).

SUV: Sport-Utility Vehicle.  Large pondering vehicles that reside in the
left lane doing 65, noted for their fine handling and excellent gas mileage
(if you need to ask....).  They are the yuppie-mobile of the 90's and
beyond.  So popular our buddy Al wants to tax them extra. Usually driven by
a clueless person with a cellphone stuck to one ear.  At stoplights, said
clueless person can often be seen reading the newspaper.  Unfortunately,
this phenomenon does not stop when the lights go green.  Some say this is a
vehicular example of Darwin's laws.  We'll see......
Scoobie or Scoobie-Doo: Subaru (affectionate term)

oh-so-reliable door handles on Type 44 and others.
Torsen, T*sen, T*rsen: another type of differential, gear based.
Triple Square: A driver design that resembles a 12-pointed star, with 90
degree ends.  Imagine 3 super-imposed squares with a 120 degrees rotation
in relation to each other ("tips" 30 degrees in relation to each other)
--or-- a 12 pointed Torx.  Use the correct tool because while Torx bits
will fit a 12-point head and _sometimes_ work, when (not if, when) they
strip, you're up that proverbial creek.
UFOs: UFO shaped front brake calipers sometimes used by AoA while on the
Roswell project, a form of military technology transfer.
UK-QOC: UK Quattro Owners Club
Ur: Original in German, refers to the Original Quattro. e.g. Ur-Q, urq, UrQ

number.  This almost always indicates a special tool that VAG recommends
you use to perform some sort of basic system maintenance.  Of course, you

expensive is an understatement.  Some genius came up with this system (see
