I'm thinking of moving to a diesel 159JTDm and possibly buying from the UK.

A lot of owners have drilled the DPF (why?) and completely removed the EGR.
I'm not sure if the JTD 1.9 engine has swirl flaps but these are possibly removed too.

However, if I import one with these mods, am I screwed with the NCT emissions test?
