iDrive Service History Retrospective Update - M135i

[rlli]

Hey all,

Have been looking at picking up a used M135i, one of the cars I was interested in has the following service history:

21k – Serviced by BMW (recorded on iDrive)
42k – Serviced by independent (not recorded on iDrive)
45k – Current mileage

Just wondering whether the service done by an independent can retrospectively be added to iDrive? Either through BMW dealer or someone with BimmerCode etc. Have done a few searches but haven’t found anything conclusive.

Thanks!
