Some normally aspirated Audis have a failure mode which results in incredible
plumes of white smoke exiting the tail pipe- and it's a cheap, simple problem,
not requiring a new engine.

Some models with a vacuum-operated power brake booster also have a check valve
in the line running from the intake manifold to the vacuum assist unit. When
this check valve fails, the engine vacuum can draw brake fluid from the assist
unit. Replace the check valve, smoke goes away!

Look for a larger diameter vacuum line running from the intake manifold to the
large black cylindrical assist unit mounted on the firewall. See if you have a
small device in the line somewhere; usually, it's a two-toned in color (black
and white, but on mine the white is always beige); it has an arrow pointing in
one direction. Remove it; if it passes air in both directions, it's bad. Get a
new one, put it in, see if your smoke goes away.
