No VW diesels until 2008 model year.There are some holdover 2006 diesels at some dealers.VW needed a while to make the changes new EPA regs required.

PS VWs small diesel cars get very good hy mpg-maybe 90% of what a Prius or HCH 2 get(low 40's),the city mpg is quite a bit less than a Prius, but still very good-very slow of course.
