Afternoon Phil,
there should be another 4 x numbers after the 03L906023 A / B number, these 4 x numbers are the software version.
The latest version of software for this ecu is 9971.
However without seeing what version of software it is currently on I cant advise why it has been updated (unless it is currently on the latest software?)
