Got lucky I guess...?
Most other folk that have done this EGR delete seem to have ended up with a check engine light. But maybe the M57TU DDE 5 map on the 330d and 530d cars are very different - the reports of a CEL after an EGR delete are mainly from these vehicles. And what
Clavurion says is also probably relevant - different markets have very different maps.
I've never done this mod myself (my EGR is clean and working fine) so I have zero first-hand experience.
