Before making any FDL modifications, always read the coding data from the module, select the underlying NCD file, and save an unedited copy to a secure backup folder on your computer.

– Expand the SVT tree and locate the ECU you wish to code. For example, to adjust lighting settings, you might choose BDC_BODY or FEM_BODY depending on the chassis.

VO coding updates the car’s master blueprint to recognize newly installed factory hardware (e.g., retrofitting paddle shifters or LCI taillights). Go to > Coding .

– Switch to the “SVT” (System Variable Tree) tab, then click “Read”. This builds a tree of all ECUs present in the vehicle, along with their current CAFD versions. The SVT can also be saved for later reference.

However, if you own a modern G-series or an electric i4/iX, you must look to ESYS 4.x or paid tools like BimmerUtility. The security protocols in modern BMWs (S18A, S18S) have effectively locked out 3.40.2. Before making any FDL modifications, always read the

FDL (Function Data List) coding allows you to change individual lines of code within a module. Examples of popular modifications include: Disabling the Auto Start/Stop feature by default. Enabling Video in Motion (ViM) for passenger entertainment.

Use an (Ethernet to OBD). For F-series, a standard ENET works. For early G-series with ESYS 3.40.2, you may need an ICOM emulation, but most G-series work via direct Ethernet with the correct connection profile.
