Audi has replaced the 2.0FSi and 2.0TFSi engines with a new 1.8TFSi for the latest 4 cylinder models. The six pot 3.2L remains and in some markets, the 2.7L as well.
The old 2L engines have been phased out as far as the A4 is concerned. I am not too sure about USA but this should be true round the world.
Nope, the current A4 in the USA (2009) is either a 2.0 Turbo or 3.2, my friend just bought one.
