New Parts list for Face Lifted Conversion. (Front & Rear)
 

based on Parts List for Face Lifted BMW X5 Contributed by LeMansX5,

it shows everything you need for face lift conversion, but only listed part number of 3.0i & 4.4i bumper with headlight cleaning system and PDC and contains old part numbers.
so, I've made new version of parts list for face lifted X5.
hope LeMans doesn't mind ;)
