How to solve BMW FEM/BDC OBD Programming Coding Loss by Xhorse BIMTool Pro

When you program the BMW key by Xhorse VVDI BIMTool or BIMTool Pro, it may appear the issues below:

BMW CAS4+ and FEM/BDC OBD show unsupported versions and require upgrades.

BMW CAS4+ and FEM/BDC OBD preprocessing completes but indicates coding loss with no recovery possible.

BMW OBD Preprocessing is unexpectedly interrupted due to missing SWFL version, halting further processing.

The vehicle's SWFL or coding version mismatch causes functional deficiencies.

You can check this article to find the solution if you encounter these issues.

Here we take the FEM module as an example.

When the SWFL, CANFD coding, and key position are missing, we can use to solve the issues by the following steps.

Step 1: Connect tools

Connect VVDI BIMTool Pro and computer via USB cable

Connect BIMTool Pro and FEM/BDC module via OBD cable

Step 2: Connect car

Run BIM Tool software

Select “Fxx/Gxx Program/Code” on the main screen of the software

Select “Auto detect” in the dropdown menu and click on “Connect car”

Step 3: Calculate programming

After detecting the vehicle info, click on “Vehicle programming”

And click on “40 FEM (FEM BODY)” and “Calculate programming file”

Detect programming file which calculated successfully for the vehicle. Press “Yes” to load the calculated programming file directly

Note: The “target istufen lev” should be the same as the “Shipment date”.

Step 4: Programming

Tick “40 FEM (FEM BODY)”

The gray area indicates the module’s current version information

The orange area indicates the calculated programmable information

Click on “Programming” to proceed

After the programming is completed, click “DTCs” to read the vehicle’s DTCs and clear them.

Step 5: Key learning

Click on “FEM/BDC Key Learn”

And click on “Get Key Info”

Now the CANFD coding and key position info have been restored.

Alright, BMW FEM/BDC OBD programming coding and key position loss issues have been resolved.
