Siemens MS42 Files


Siemens MS43 Files


This is the latest software version ever published for the MS43 by BMW.

The E39 5 series was already out of production when the MS430069 hit the streets, so we ported all the changes from the latest MS430066 to the v69 code base.

These files are fully compatible with the MS4X Community Patchlist.
