The Bluetooth control module in the Discovery 4 L319 is responsible for managing phone calls and data transmission between the vehicle and mobile devices.

- correct integration with the vehicle's factory software,
- stable operation of hands-free and multimedia functions,
- compatibility with the existing wiring harness and connectors,
- preservation of the original operating logic from the steering wheel and radio panel.
A used OEM part is a sensible choice for servicing premium vehicles – it allows you to maintain the vehicle's character and functionality at controlled repair costs.
Condition, Verification, and Installation
The module is a used part obtained from disassembly, which means it retains its factory design and compatibility while offering reduced costs. Before installation, standard diagnostics of the vehicle's electrical system are recommended, including checking power, grounds, and bus communication, to rule out other sources of faults.
In most cases, installation is a plug-and-play replacement for the damaged controller, using the original brackets and mounting points. Depending on the car's configuration, adaptation or coding using an appropriate diagnostic tester may be required after installation for the module to be correctly recognized by the vehicle's system.
