New Service - FEM and BDC Cloning

We are excited to add new offer to our service list.

We see more and more failed FEM/BDC modules, Mainly they are damaged by cheap clone tools that are used for adding keys or matching with DME/DDE modules.

We've been Cloning / Reviving / Repairing them before but as number grows we decided to make separate page for it on our website.

This along with many other our services are mainly for shops and technicians who work on BMWs.


More Details

What is FEM or BDC?

Some models of F series switched to FEM and BDC from CAS modules

  • FEM stands for Front Electronic Module 

  • BDC stands for Body Domain Controller

These two are pretty much the same

FEM is used on

1 Series - F20, F21 (and F52 in China)

2 Series - F22, F23, F45, F46, and F87 (M2) 

3 Series - F30, F31, F34, F35 and F80 (M3)

4 Series - F32, F33, F36, F82 and F83 (M4)

BDC is used on

X1 - F48 and F49

X2 - F39

X3 - F25

X4 - F26

X5 - F15 and F85

X6 - F16, F86

Mini - F54, F55, F56, F57


The main reason of failed FEM and BDCs we have seen is done by cheap tools trying to add keys to them and failing

Obviously the other reason is when it gets flooded. 


We do offer Cloning or Repairing service for existing FEM or BDC

How it works:

1) You will need to send us original FEM or BDC module,

2) We will check it and if its not repairable we will clone it to other unit.

3) Ship it back to you
