How to Solve Yanhua ACDP Module 31 Error “System status: Normal, need upgraded”

Customer problem:

When I used Yanhua ACDP2 with Module 31 to write coding on my 2015 X5 xDrive 30d BDC via OBD, a prompt appeared on the screen “System status: Normal, need upgraded”. What can I do?

OBDExpress.co.uk engineer replied:

The version is low and needs to be restored.

Please operate as follows:
Select BMW>> FEM/BDC>> Restore
Complete the steps below:
Step 1: Backup coding data
Step 2: Program the FEM/BDC system
Step 3: Write coding data
Then use other tools to set coding.
(If the chassis is F15, you can use Autel MaxiPRO MP808S)
