Help Needed and Hello

[oldblue1993]

Hey all, new here so forgive me well I am learning the site. Just brought home a 04 x5 3.0i , Come to find out I have major brake issues. The vacuum booster does not hold vacuum"tested with vacuum pump" and when I scan I get a fault in the dcs "only brake light is on".
I have purchased a new booster and a new abs module "will be in in a couple days" "figure this was why it was cheap"

My question is, will I need to code the abs module "exact same part number" and will I need to activate the abs to bleed?
I am stuck for cash as this has already chewed up more then anticipated and I see the Inap software may be able to activate abs, but finding it for the E53 seems fruitless, could anyone point me in a clear direction on this.

Oh and thank you for having me here.
