Adaptive headlights, also known as dynamic headlights, are a popular feature on modern BMWs, including the F10 5 Series. These headlights enhance visibility by swiveling horizontally, illuminating the road ahead as you turn the steering wheel. However, if your adaptive headlights on your BMW F10 are damaged, you might consider replacing them with non-adaptive units. This guide will discuss the process of replacing adaptive headlights with non-adaptive headlights on a BMW F10 and the necessary coding adjustments.
Replacing adaptive headlights with non-adaptive headlights on a BMW F10 requires not only physically swapping the units but also coding the car’s computer system to recognize the change. The original poster in a forum discussion inquired about the feasibility and potential challenges of such a swap on their 2014 F10 LCI. The initial confusion stemmed from a lack of clarity regarding the reason for the replacement. While initially perceived as a cost-saving measure (new non-adaptive headlights were purchased for £1200 on a Black Friday sale), it was later revealed that the original adaptive headlights were damaged in an accident.
The primary concern with replacing adaptive headlights (option 524) with non-adaptive ones is the potential for error messages. The car’s Front Electronic Module (FEM) or Footwell Module (FRM) needs to be recoded to prevent this. This involves removing option 524 from the vehicle’s order (VO) using coding software such as ESYS or potentially Bimmercode in expert mode. Recoding the existing module is generally possible, eliminating the need for a new one.
The process involves several key steps:
Understanding the Coding Process for BMW F10 Adaptive Headlights
The coding process is essential to avoid error messages after installing non-adaptive headlights. The car’s computer system needs to be informed that the adaptive functionality is no longer present.
- VO Coding: This involves modifying the Vehicle Order (VO) to remove the code for adaptive headlights (option 524). This tells the car’s system that this feature is no longer equipped. ESYS software is typically used for VO coding.
- FRM/FEM Coding: After changing the VO, the FRM (or FEM in later models) needs to be recoded to reflect the change. This step ensures that the module controlling the headlights operates correctly with the new, non-adaptive units.
Potential Challenges and Considerations
While replacing adaptive headlights with non-adaptive units is possible, there are some potential challenges to consider:
- Coding Expertise: VO coding and FRM/FEM coding require specialized knowledge and software. If you’re not comfortable with coding, it’s recommended to seek professional assistance from a BMW specialist or coding expert. Incorrect coding can lead to further issues.
- Software and Hardware: You’ll need the appropriate coding software (ESYS or Bimmercode), a compatible cable to connect to the car’s OBD-II port, and a laptop.
- Backup: Before making any coding changes, it’s crucial to back up your current coding data. This allows you to revert to the original settings if any problems arise during the coding process.
Conclusion: Successfully Replacing Adaptive Headlights on Your BMW F10
Replacing adaptive headlights with non-adaptive versions on a BMW F10 is achievable with proper coding. Understanding the coding process, potential challenges, and seeking expert help when needed are essential for a successful conversion. This modification can provide a cost-effective solution for replacing damaged adaptive headlights while maintaining essential lighting functionality. Remember to prioritize safety and consult with experienced professionals if you are uncertain about any part of the process.
