detailed, with HQ photos and explanation

The BMW LCM (Light control module) most often fails due to water infiltration. Since the BMW LCM is combination of a light module and a check control module, the LCM failure usually results in lights-related problems or monitoring malfunction (pressure monitoring, wrong mileage shown etc). Replacing a LCM is a cumbersome procedure: there are many versions for one particular car model and you need to find the exact same version your car is equipped with.


A faulty LCM module can have many consequences. The following symptoms usually indicate a faulty BMW LCM module in need of a repair:

Headlights remain on after the car is shut down
Headlights do not turn on or function intermittently
Indicators flash randomly
Non-functional high beams
Brake lights do not function or are intermittent
Turn signals do not blink or blink too quickly
Emergency hazard lights do not blink or blink too quickly
The dashboard is no longer lit
