This manual introduces how to conduct BMW FEM/BDC ECU Renew on Auro OtoSys IM100/IM600 key programmer.
Two options are available when accessing FEM/BDC Renew:
Copy Data Update : When the immobilizer information of the vehicle can be read
from the original FEM/BDC module, perform this function to read the information
and write it into the replacing FEM/BDC module.
Calculate Data Update : When the immobilizer information of the vehicle cannot
be read from the original FEM/BDC module, perform this function to generate
the information via the input VIN code, vehicle frequency and engine ISN code
and then write it into the replacing FEM/BDC module.
NOTE
Illustrations used in this manual are samples, and the actual testing screens may vary by
vehicle. Observe the menu titles and on-screen instructions to make correct selections
and operations.
FEM/BDC Renew via Copy Data Update
Preparation
1. Attention: If there’s an ELV in the vehicle, the ELV may not be unlocked after
performing FEM/BDC Renew. You’ll need to solve the locked problem yourself, so
please start the operation with careful consideration.
2. To perform the Copy Data Update function, a working key or the engine ISN code is
needed.
3. The hardware version of the original and replacing modules can only vary slightly.
Otherwise, the DTCs of the vehicle may not be cleared.
4. Remove the FEM/BDC module from the vehicle.
8). Remove the module from the vehicle.
5. Conduct ECU preprocessing on the replacing (used) module and the original module
to make them able to learn keys. No ECU preprocessing is needed for the replacing
module if it is a brand new one.
6. Prepare a blank key.
Procedures
1. Connect the OtoFlash to the original FEM/BDC module via the included main cable.
2. Connect the OtoFlash to the IM600 tablet via USB connection.
3. Turn on the IM600 tablet and tap OtoSys > IMMO. A vehicle menu displays and a
disclaimer prompts up. Tap Accept to continue
NOTE
1. You can click the icon near the top-right corner to record the operation data. If you
encounter any difficulties, click the icon again to send us the data and the problem,
so that our engineers could help. The network should be connected when uploading
the data.
2. Please make sure the engine is off before the operation gets started.

data.
NOTE
If the working key is verified in this step, it can be directly used to start the engine when
the FEM/BDC Renew is completed.
11. When the immobilizer data is read successfully, tap Save > Confirm to save thedata. When a “File saved successfully!” message displays, tap OK > Close and exit
to the function menu.
NOTE
1. The data file can be renamed.
2. Memorize or note down the name and location of the file for later use.
12. When Read Immobilizer Data is completed, connect the OtoFlash with the replacingmodule via the included main cable.
13. Then tap Write FAFP to write the saved FAFP data into the replacing FEM/BDC
module. Read the function information and tap OK to continue.
14. Select the saved FAFP data file and tap Confirm to complete Write FAFP. Then tapOK and exit to the function menu.
15. Tap Write immobilizer data to write the saved immobilizer data into the replacingmodule.
16. When a module menu displays, make selection accordingly.NOTE
New Module: Perform this function if the replacing module is a brand new one.
Used Module: Perform this function if the replacing module is a used one.
18. Tap Write data to ECU. When Write Data to ECU is completed successfully, tapClose and exit to the function menu.

21. Tap Key learning to add a key to the new FEM/BDC module. Read the functioninformation and tap OK to continue.
NOTE
1. The password must be read out before the key can be written or cleared.
2. A key position must be selected before the key can be written or cleared.
23. When a “Do you have a working key?” message displays, make selectionaccordingly. Tap Yes and then put the original key close to the emergency start coil
to read the password information, or tap No to input the engine ISN code.
25. Follow the instruction to put the NEW key close to the emergency start coil and tapOK to start Key Learning.
26. When a “Write Key successful!” message displays, tap OK to check the key ID status.Then tap Close to exit to the function menu.

successfully, Copy Data Update is completed.
28. Install the replacing FEM/BDC module into the vehicle and check if the engine canbe started.
NOTE
1. DTCs may be detected and specific machines are needed for programming, coding
and clear DTC.
2. If the remote function of the original working key doesn’t work after the operation,
please disable the key first and then enable it via Expert Mode > FEM/BDC > Key
enabled/disabled.
