Huh? Some certainly don't, but 2014 TDI Passats like mine use DEF. My reservoir currently lasts about 10000 miles, which is also the manufacturer's service interval.
I was not aware that both versions were affected -- looks like this information came out a bit later. I'll edit the original post.
Edit: Or not...looks like too much time has passed.
