Here is the user guide about how Auro OtoSys IM100 renew BMW FEM/BDC. There are two ways that Auro IM100 could do BMW FEM/BDC renew: via Copy Data Update or Calculate Data Update. This guide will share both in two part.
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 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 module.
Note: this guide is an operation as sample, while the screen may not the same as shown in this guide. It depends on the car model.

Part1: FEM/BDC Renew via Copy Data Update
Before you do FEM/BDC renew, please prepare:
- 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.
- To perform the Copy Data Update function, a working key or the engine ISN code is needed.
- The hardware version of the original and replacing modules can only vary slightly. Otherwise, the DTCs of the vehicle may not be cleared.
- Remove the FEM/BDC module from the vehicle. (See Appendix.)
- 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. (Please refer to BMW-A001 for details on ECU preprocessing.)
- Prepare a blank key.
