In details...

Step 1: read key info

MUST read key information first

Step 2:pre-process FEM/BDC system

MUST DISCONNECT THE BATTERY

1: OBD back up original coding data:

On the car or test platform, connect to FEM/BDC system, then back up original back up coding files

2: read out EEPROM backup data & generate a service-mode EEPROM:

-> Disassemble FEM/BDC module, find out chip 95128 or 95256, read EEPROM data usinga ECUprogramming tool: VVDI-Prog,Orange5and the like;

->Copy the EEPROM data into to theLonsdorK518ISEcustomfilefolder;

->Run the program, read original EEPROM data and generate a service-mode EEPROM, upload data of the service-mode EEPROM, write it into chip 95128 or 95256 with help ofa ECUprogrammer

->Restore FEM/BDC system, supply battery to the car and connect

3: programming

->This stepneedto be done on the BMW FEM/BDC test platform;

->Make sure that Step 1 & 2 is finished

->Connect FEM/BDC system to power supply and connect

4: restore EEPROM data

-> disassemble FEM/BDC module, write original EEPROM data (Step 2) into chip 95128/95256

-> restore FEM/BDC system, connect to OBD

5: restore coding data

-> load the backup coding files (Step1),restore coding information

6: pre-processing is complete.

Step 3: make a dealer key

1:LonsdorK518ISE read out data, select the will-be key position

2: a "used”keyto make a dealer key

All keys lost: enter 32bit ISN codes to make a dealer key

3: put the key near the carimmoinduction loop

4: detect the original key, read outimmodata

5: put a new key near the carimmoinduction loop

6: detect thekey key, key learn (don’t move the key, keep stable)

7: key learn is complete

Step 4: disable the key

1:LonsdorK518ISE read out data, select the key ID position to disable

2: put a "used” key near the car induction loop

3: K518ISE system tries to connect to CAS, disable the key with current ID position, disable key successfully

Step 5: enable the key

1:LonsdorK518ISE read out data, select the key ID position to enable

2: put a "used” key near the car induction loop

3: K518ISE system tries to connect to CAS, enable the key with current ID position, enable key successfully

Step 6: delete the key

1: K518ISE read out data, select the key ID position to delete

2: read FEM/BDC key password

3: delete the key successfully; the key position is blank

THE MOSTIMPOERTANT IPS

1: You must read key info before everything you’ll do

2: to pre-process FEM/BDC, you should pay attention to:

- backup coding codes to continue

- disconnecttothe power supply/battery, havea ECUprogrammer to read EEPROM data,up loaddata inK518customfilefolder, read new EEPROM data loaded just now, generate service-mode EEPROM data, read service-mode EEPROM data, write data into the chip, install CPU on the car

- ECU programming: need 6 min, with power supply connected

- disconnecttothe power supply, disassemble CPU, write the original EEPROM data into the chip, install CPU on the car, connect to the power supply, make surecommunicateis successful

- upload coding files (Step 1), restore original coding info to pre-process, then make a dealer key

3: 32bit ISN codes is required to program a new key when ALL KEYS ARE LOST

Job’s done withLonsdorK518ISE!

Go to BMW Key Match

The current FEM/BDC needs to update the ECU program before performing key matching. Please ensure that the car battery has enough power, the programming process, please keep the equipment cable connection

Please remove the FEM/BDC and then use the CGDI Prog programmer to read and save data from the P5XXX EEPROM chip on the FEM/BDC computer board, then click on Next

Read the original car EEPROM data file

Use the CGDI Prog BMW to write the calculated new data to the 95XXX EEPROM chip, then put the FEM/BDC back into the car,thnclick on Next

Car battery voltage: 11.93V

Prepare the programming ECU

Security authentication is in process

Safety certification through

The ECU is being programmed

step 5:

loading coding file (read step 1), write to FEM/BDC ,finish FEM/BDC programming

Attentionplease!!!

- You can directly backup/restore coding

- You have to pre-setup the FEM/BDC module before deleting/adding keys or resetting keys

- You’ll be told other tools need to be used first to program the FEM/BDC system, then setup FEM/BDC via VVDI2. It happens when you do FEM/BDC key learning, and you don’t have a working software version

- You’d better not close the VVDI2 interface when you pre-setup FEM/BDC

- You need do with 95128(FEM) or 95256(BDC) chip when pre-setup FEM/BDC

Note: there are two 8-pin chips; do not disassemble the wrong chip; better refer to the wiring diagram

- You must restore original EEPROM data, restore coding when pre-setup FEM/BDC. If you fail to restore coding or the remote cannot start or something wrong with the window (or other failures probably) after coding restore and FEM/BDC installation, please use other tools to do re-coding FEM/BDC

- Ask tech support @obdexpress.co.uk for help, if the replay soundscontinuouslyafter supplying power to the FEM/BDC. Usually, it needs programming.
