Quick Answer
BMW Speed Limit Assist (SLI) coding activates the Speed Limit Info system, which reads traffic speed signs via the front camera (KAFAS) and displays the current speed limit in the instrument cluster and Head-Up Display. The feature is present on most G-series BMWs but disabled by factory software in certain markets. Activation is a remote ENET coding service — no hardware required, session takes 20–30 minutes.
