FDL (Function Data List) coding allows you to change the values of individual operational parameters within an ECU. This lets you toggle hidden features on or off without altering the global vehicle profile. Examples include: Disabling the default behavior. and selecting the appropriate TargetSelector (e
Open the NCD file, change your values (e.g., from nicht_aktiv to aktiv ), save, and hit "Code FDL." Safety First: The Golden Rules
