we have not worked with the replacement of controllers yet...
but from the autoscan I can see they have different part numbers...
the fault code:
37685
Discrepancy in values of total mileage between BMS-KP and KOMBI (instrument cluster)
The fault is currently present.
you will always get when replacing either a BMSK or a Cluster... as the mileage is backed up in the BMSK... This can be fixed by BMW on a GT1.. from what I've learned, this can ONLY be done on a GT1 (if it is a used unit) as the the 3rd Generation MOSS only allows setting of the mileage on a NEW cluster (to promote the replacement of NEW units only)
is this a Used or a New cluster ?
Then it will need to be "matched" or "married" as well.. as every cluster saves the bikes VIN number etc, and if that's a mismatch, the unit bike will not be happy either...
I still intend to play with matching/replacement of Control units, but that's a bit down the line... too much else to do at this point...
best,
Stephan
