This is the latest software version developed for the Siemens MS43 and was released by BMW in 2005.
The E39 5-series was already out of production when the MS430069 hit the streets, so we ported over the calibration data from 66 to the 69 code base.
- LHD (left hand drive) and RHD (right hand drive) differ in exhaust gas temperatur models because of the different catalytic converter configuration.
- US and EU differ in diagnosis configuration.
- These files are fully compatible with the MS4X Community Patchlist
Please use the most suiting file according to your needs:
- E46 3-series
These are the older original Files from the MS43 Tuning Thread on e46fanatics.
They are listed here for archival reasons, Please consider using the MS430069 files and the patchlist instead.
