MS430069

This is the latest software version developed for the Siemens MS43 and was released by BMW in 2005.

Notes:

• 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. EU2 and EU4 are different in catalyst configurations.

Please use the most suiting file according to your needs:

• E39 5-series
  • M54B30: EU4 LHD || US

• E46 3-series
  • M54B22: EU4 LHD || EU4 RHD
  • M54B25: EU4 LHD || EU4 RHD || US
  • M54B30: EU2 LHD || EU2 RHD || EU4 LHD || EU4 RHD || US

• E53 X5-series
  • M54B30: EU4 || US

These files are fully compatible with the MS4X Community Patchlist.
