Are you experiencing annoying flickering LED lights in your BMW F15 after an upgrade? This is a common issue, and fortunately, it’s easily solvable with Carly BMW coding for your F15. This guide will walk you through understanding the cause of this flickering and how Carly coding can help you eliminate it by adjusting the voltage monitoring settings in your BMW F15.
BMW vehicles, including the F15 X5, are equipped with sophisticated systems to monitor the functionality of their lights. This system includes voltage monitoring to detect if a bulb is burnt out. However, when you switch to LED lights, which consume significantly less power than traditional halogen bulbs, this voltage monitoring system can misinterpret the lower power draw as a malfunction. This misinterpretation often leads to the frustrating flickering of your LED lights.
The good news is that with Carly BMW coding and an OBD2 adapter, you can easily access and modify your BMW F15’s control units to deactivate this voltage monitoring for specific lights. By doing so, you tell your BMW that the LED lights are functioning correctly, even with their lower voltage draw, thus eliminating the flickering.
Let’s explore the specific voltage monitoring parameters you can adjust using Carly coding on your BMW F15. These settings are typically found within the GBDCMAIN (Body Domain Controller Main) module of your vehicle.
Voltage Monitoring Options for Lights on BMW F15
With Carly BMW coding, you have granular control over voltage monitoring for various lighting systems in your F15. Below are the parameters you can expect to find and adjust to resolve LED flickering issues. For each light type, there are generally two parameters: one to activate voltage monitoring and a second to deactivate it. You’ll want to deactivate the monitoring to stop flickering with LEDs.
