Hi everyone, i'm new so be nice............

This may sound like a daft question but I was just wondering.....

I have a 2006 A4 Avant 2.0T quattro and some nice lady ran into the back of me last week so I am having a complete new bumper being fitted on insurance. As I have factory fitted reverse parking sensors, does the new bumper the repair centre orders come with the holes already in it or do they have to drill new ones????? Just curious as I obviously want it looking perfect as it was before the shunt.

Does anybody know such information???
