According to Maverick's site: Volkswagen Australia Passenger Vehicle Model Year 2012 (MY12) Changes | my-gti.com
There's no MY12 Tiguan at this point in time!
So supposedly still rolling out MY11 after calendar week 22 (i.e. June 2011).
Therefore, there can be no mistake or way of denying that MY12 is referring to the "facelift" model and nothing else!
