When I took delivery of my car 21 months ago, the person doing the handover stuck the vehicle data stickers (one on the boot floor, the other in the owner’s manual) during the vehicle handover. I seem to remember it was an item on their handover checklist rather than something that would’ve been done as part of the PDI.
If it’s the PR codes you’re specifically interested in, then your dealer should be able to provide you with a print out of your car’s build data sheet and that ought to include the PR codes.
