F30 owner complaints:

I have a problem with my BMW F30 2014
I change the FEM ( buy a new FEM by BMW)
And now i try with Ista P (Icom a2) to coding the FEM. But always failed to that.

Below is a the suggestion of BMW FEM coding… Wish helps

You need:

An BMW ENET cable for connection (Ethernet to OBD)

Working E-SYS to save the FA from the old FEM. Don’t think you can with ISTA.

E-SYS vsISTA:

With E-sys you can read and save VO to a file.
If you don’t have ISTA license and you are not online, this is the way you can transfer the car VO to the new FEM.
If you haveISTAlicence and you are connected to BMW servers, then ISTA-P will download VO automatically and insert it into the new FEM.
How to code a new FEM:
1. plug your old FEM (I hope it is not completely dead and you can still read VO from it) read VO and save it to a file with E-sys.
2. Disconnect old FEM and plug new FEM, then connect with ENET cable to the car, go to VCM and load VO from the file you saved previously. Then go to master tab and click "write FA” which will write the car VO to the new FEM.
3. Start ista-p and when you see window for replaced modules click Yes and when you see the list, in the bottom tick FEM. ISTA-p will code(configure) and initialize the new FEM to the car.
How to code an old FRM:

I have read both, that Immobilizer (EWS4) is an issue for FEM, and that it is not. For sure it is an issue for DME replacement. I don’t think attempting to flash FEM would do anything to DME. Worst case is FEM takes VIN, and still won’t sync / decrypt key with DME.
