VW's 3 Year Extended Warranty

[yowie]

So you are agreeing with my assumption that it is a clever way for VW to keep you for another 3 years of servicing...?

You could look at it that way, Jetta, or maybe look at the number of things that, were any one of them to fail with-in the next three years, alone would justify the 1300 odd cost. Try pricing a head unit or gearbox or cracked head for that matter.
In my humble, its a no-brainer. Unless you have the original fail-safe DSG, go for it
