its more about the cost of the work booking it beforehand, then saying hello on the day and filling out paperwork (and charging for work done at pick up), then the tech taking 10 mins to find and get in the workshop, and then plugging it in to talk to base to see what muddle up the bike is in - altogether that'll be 30 mins chargeable labour easily - and the rental on the dealer online diagnostic equipment on a Merc is €12000 a year ongoing - I expect a BMW dealer won’t be charged much less to lease the equipment
I can see a number of pitfalls
1) the VIN listed in the cluster unit now on your bike isn't likely to be your bikes original VIN so BMW systems will bulk at any further work - unless someone has helped you sort this - its all doable just not easy and most don't have the kit. No idea how on the TFT cluster from 2017 to 2024, but I bet its doable. (note: this is not case on newer 2025 model year bikes, they have a new setup stopping play)
2) it maybe that HEX have done some work that maybe give insights on both the VIN change and the Mileage issue - worth asking the question
3) maybe you are unaware - the TFT clusters have been full of quite buggy software and a number of minor issues, and with user weirdness and features not behaving - there is about 10 cluster software updates that say a 2018 bike hasn't got vs an up to date 2024 unit has
so if the VIN inside the unit is OK it likely needs an update and you could come out in a good place....
