Thank goodness that no class B's (to my knowledge) use the VW diesel platform! Hopefully, as well, that Mercedes hasn't been playing any dirty tricks with the Sprinter's emissions.:S
about a week before the VW pantload, the Guardian UK was reporting the EU and UK regulators were looking at diesels from MB, BMW and VW group for emissions above allowable limits.
The EU recently adopted regs similar to 2010+ US regs ( 2009 California).
