Re: code P0470
sounds like your DPF is fouled up, in which case you need to try a DPF regeneration, try driving it for a prolonged period ( 20 minutes or so ) holding it at extremely high RPM's,
apparently this can burn off the built up particles that the DPF is designed to trap,
an other way is have a Lexia run a forced re/gen

It could also be a blocked catalytic converter but try citronuts idea first as its an easy fix.

Re: code P0470
Could be the DPF blocked or blocking.
