The I-levels (Integration level) are 2 sets of numbers known as the Factory I-level and the Dealer Organization I-level (also known as "Actual I-level"). These I-levels represent the software/data release versions programmed into the vehicle.
The Factory I-level (sometimes referred to as the "model I-level", represents the software release when the vehicle was built.
The Actual I-level (sometimes referred to as "vehicle data release", represents the current software release programmed in the vehicle.
The I-level typically looks as follows: K024-09-08-500,
The 1st set ("K024") represent the chassis/build type (K024 represents all CAN-bus enabled models, K2x, K4x, K7x etc.) ,
The 2nd set ("09") represents the year of the release,
The 3rd set ("08") represents the month of the release and
The 4th set ("500") represent a version for that release - a bug fix or update on this could be: K024-09-08-550 or K024-09-08-600
I've read that If your motorcycle does not have the absolute latest I-level, it does NOT necessarily mean that it's Firmware is out of date or that it needs a Firmware update. The ECU's have a limited number of times that the Firmware can be updated, and thus a Firmware update is only released by BMW, for specific models... you might have a K024-08-02-500 I-level (released February 2008), but that does not mean that it is not the most up to date version of the Firmware available for your model!
Does anyone know if there is a list of the latest (up to date) I-levels per model?
My '07 K12GT shows:
Factory I-Level K024-07-01-500
Actual I-Level K024-08-01-500
Seems like pretty old firmware but it might actually be current considering the model is discontinued.
