[Biturbos4] Smoking and high oil consumption in cold weather solved

[be_larson at access-4-free.com]

A week or so ago, my 2001 a6 2.7tq/6 speed smoked
excessively on the way home from work.  It was negative 20
degrees F, and the car had warmed up for 5 minutes after
starting due to the cold weather.  The car burned 1 quart in
15 miles on the way home, and I at first thought, crap I
have a bad turbo!  But the problem ended up being a froxen
breather hose on the back of the motor, and FYI, the three
Audi dealers I talked to in Minnesota sold two dozen of
these parts in January, so it seems to be a common problem. 
The part was around $200, and I installed it myself, it took
a few hours.  Part number depending on your car is
078-103-235-r (or B, G, etc).  My car had a R part on it,
and the replacement was insulated, so the problem might not
happen again?  Just posting this for archive information.
