Technically, as far as regional production release, they are correct, BUT it is only regional specific production packages. Using the same release versions, it does NOT make a difference. So it’s really a non issue in this case. (See the chart below.)
See above, regional production release. Sometimes the files are the same.
The 7D0-09-xx series is optional feature set menus that allow you to access the vehicle features thru the center stack display, or Sync. Most of them don’t apply to pre-2019 vehicles. However, some do and can be useful. You will need to upgrade the firmware to obtain these, as well as reload the asbuilt completely once that is done. Then you can use FORScan to turn on menus to access features of the vehicle. The 7D0-09-xx set does not add any features to the vehicle itself.
Calibration may be updated using FORScan but you have to follow a specific order below:
GB5T-14G376-AA.vbf (Bootloader) //Mandatory
XXXX-14G374-XX.vbf (Direct Config Configuration) //Mandatory
XXXX-14G375-XX.vbf (ECU Calibration Data) //Mandatory
GB5T-14G379-AA.vbf (ECU Cal-Config #1 AKA Audio Profiles) //Optional
XXXX-14G379-XX.vbf (ECU Cal-Config #2 AKA Illumination) // Optional
To determinate if a calibration is for a MY18.5 you have to read the first XXXX, they must have 1U5T or 5U5T. Also, it’s important to keep in mind that file 14G375 is different based on APIM region and Flash size:
XXXX-14G375-A*.vbf 8GB / 16GB EU without NAV
XXXX-14G375-B*.vbf 8GB / 16GB NA without NAV
XXXX-14G375-C*.vbf 8GB / 16GB ROW without NAV
XXXX-14G375-D*.vbf 32GB NA with NAV (Telenav)
XXXX-14G375-E*.vbf 32GB CHINA with NAV
XXXX-14G375-F*.vbf 32GB (ANY region) with NAV (Telenav)
XXXX-14G375-G*.vbf 32GB ROW With NAV (NNG)
XXXX-14G375-H*.vbf 64GB EU with NAV
XXXX-14G375-J*.vbf 32GB TURKEY with NAV
XXXX-14G375-K*.vbf 32GB UAE with NAV (NNG)
Based on the calibration files, it looks like your vehicle is a pre-18.5MY. (They are GB5T.)
Your APIM is clearly a pre-18.5MY unit looking at the .vbf information. I will tell you that updating this unit with the most current .vbf cal files will most likely result with incompatibility issues. The hardware is different than the 18.5MY and up APIM’s. Subtle differences, but enough to be an issue.
