Crankcase breather hoses: Cold weather and NO oil

[SuffolkD at aol.com]

Here is a post about a winter driving student who couldn't make the event 
because he had no oil on the dipstick and his CEL was on.
Feel free to pass this on to anyone you think would benefit from this.
MY Q is:
This a 2.7 T thing or any V6?

Guys,
 
It sounds like it was a fun weekend.   On 7:30 Saturday morning, at 27 
degrees below zero, about 10 miles before Twin Mountain, my check engine light came 
on.   There was no oil reading on the dipstick.  So, after a tow back to 
Nashua, which took most of the day and included an initial 4 hour wait for the 
truck to come, I later found out that the crankcase ventilation hoses/valves 
frozen up because of the condensation and sludge inside them.  The increased 
crankcase pressure forced the oil out through the rings.   When I picked the car up 
from Audi of Nashua later that week, there were five other Audi's with the 
bi-turbo engine with the same problem being repaired.   It turns out that Audi 
has redesigned the vent hoses to make them more resistant to freezing (i.e. it's 
a known problem).   Anyway, I'm back and running again, and looking forward 
to next winter's school.
