As said many times...
A diagnostic device (IID) for a modern vehicle is as essential as pliers, spanners etc.
In BMs case, it's now paid for itself in full...
No Flatbed ride hundreds of kilometres, no loss of vehicle use during that time, no diagnostic charges from dealer..
On top of that:
CCF editing - got that Global close working yet BM?
ECU remapping
And best of all, quickly read the vehicle and can have all ECUs (20+) updated to the latest firmware revisions quickly and effectively.
