Genuine BMW TCU Module - Telematics Control Unit — Overview

This is the factory BMW telematics control unit, not a tuning part despite how some catalogs file it. It handles vehicle communication features tied to the car's connected services architecture, so when this module fails you usually see SOS, ConnectedDrive, or communication-related faults rather than drivability issues. If you need an OE replacement for a supported F-chassis or G-chassis car, this is the right route instead of gambling on a used module with unknown coding history.

Fitment spans a pretty wide mix of cars including F30, F36, F15, F16, F26, F39, F44, F48, F90, G01, G02, and G05 applications. I would only buy this after confirming the exact part number against your VIN, because BMW telematics hardware changed by production date and option package. Also plan for programming and coding after install - this is not a simple plug-it-in-and-go repair on most cars.
