I'm going to monday-morning quarterback here and say "you shouldn't have
ignored it".

Okay, so your car is smoking like crazy, which it has NEVER done before save
the last 2-3 days when it has been getting worse..but you continued to drive
it?  It sucks having to wait for a flatbed, trying to find a ride home, etc.
It sucks even more when you blow up your engine.

You probably got the O2 sensor code either because there's a fuel system
problem and the ECU can't get proper mixture...or the O2 sensor has been
damaged by whatever you're burning(they are sensitive to contamination-
response slows until the sensor becomes useless, hence the Audi-recommended
50k-mile change interval).

Regardless, you've got a serious problem, and the car should NOT be driven
until the cause is determined, IMHO.  Provided there are no obvious leaks,
loose hoses, etc...'seek professional help' applies.  Driving the car presents
a serious chance of further damage and I recommend you have it flat-bedded to
your mechanic.
