For persistent hard faults, the vehicle should be plugged into an official JLR diagnostics terminal running . A technician can check if the Audio Amplifier Module is configured to the incorrect power mode or if an official software update patch is available to fix false-positive logging. Step 4: Physical Wiring and Module Inspection

In most 2021 Land Rover models, the amplifier is tucked away in the rear cargo side panels or underneath the front seats.

The B1D9F11 code in a 2021 Land Rover points almost exclusively to a physical wiring or connector fault under the passenger seat—not a software glitch.
