Symptoms of a BMW X7 Headlight Fault
Owners of 2021-2023 BMW X7 vehicles, along with other BMW models, may experience specific warning messages related to their high beam headlights. These messages appear on the vehicle's instrument cluster and indicate a malfunction in the lighting system. The primary symptoms of a BMW X7 headlight fault include:
- The display of the control message: "Left high beam headlight faulty"
- The display of the control message: "Right high beam headlight faulty"
Fault Codes / DTCs
When a BMW X7 headlight fault occurs, a vehicle diagnostic test may reveal specific Diagnostic Trouble Codes (DTCs) stored in the vehicle's system. These codes pinpoint the nature of the communication problem within the headlight control system.
| Code | Description | Module |
|---|---|---|
| 805A22 | MLC: Communication fault timeout FLM-03 left | MLC (Module for Light Control) |
| 805BA2 | MLC: Communication fault timeout FLM-03 right | MLC (Module for Light Control) |
Diagnosis and Trigger Conditions
The fault codes 805A22 and 805BA2 indicate a communication fault timeout with the FLM-03 (Front Light Module) on either the left or right side. This suggests that the Module for Light Control (MLC) is not receiving timely communication from the respective FLM-03 module, leading to the reported BMW X7 headlight fault. These conditions are typically detected during a vehicle test or when the high beam function is activated.
What Owners Should Do
If your 2021-2023 BMW X7 displays a "Left high beam headlight faulty" or "Right high beam headlight faulty" message, or if you suspect a BMW X7 headlight fault, it is recommended to schedule an appointment with an authorized BMW service center. Technicians can perform a diagnostic test to confirm the presence of fault codes 805A22 or 805BA2 and determine the necessary steps to resolve the communication issue with the FLM-03 modules.
