bmw e90 330d differences 56/07- 08 onwards

Hi people im wondering did the e46 330d engine get run in the e90 model? if so when did they change it upgrade it?



also ive found that the e90 330d 07 plate has different power rating to the e90 330d 08 plate onwards....



Does anyone know what was changed and why? this details are taken from parkers car guide..



Many Thanks
