Yes Chipple1 is correct. When I was looking in 2015/16 only the lower powered engines were Euro6. However all Caravels (and VW approved vans for campervan conversion), being classed as cars had to be E6 in 2015 by law, a year earlier than straight vans. VW were trying to unloading their stock of (higher powered) Eu5 engines on the van market in 2015/16 while they still could.
