The camera involved with the BMW lane departure warning is built to guide the lane sensor with proper directional measurements. So read on to learn how to solve almost any issue via a quick master reset or camera recalibration.

What Causes The Lane Departure Warning System Is Not Working?

A couple of reasons come to mind if we talk about the lane departure warning sensor of BMW. This very nifty tool lets the user stick to their appropriate lane. 

When the lane departure warning system notices an altercation on the driver’s route, it vibrates the steering wheel. This safety measure lets users know they aren’t driving in the appropriate lane.

The reasons for this navigation module not working would be:

  • Connection error
  • Recalibration Issue
  • Software bugs
  • Country-specific speed limits

Solutions For Lane Departure Warning Not Working 

The BMW lane departure warning system system warns you when you also start to displace from your route. This is a perfect preventive measure for many unwanted accidents. 

But as this is modern technology, it is susceptible to malfunctioning. Some common fixes for problems with your lane departure warning system would be as follows:

Check If The Rear Camera Is Properly Connected

The lane departure system works based on sensors and a camera. This camera is built into the rear-view glass to visualize the road ahead properly. It can capture up to 164 feet of ground in front of the car for proper guidance.

Once it captures the landmarks, the system will notify the user about any unnecessary altercation from their respective lane. This camera is a core ingredient for the system to keep on running. This is why when it gets disabled, the system will not function. 

If your lane departure system is not working, check if the rear camera is connected correctly. You must connect it when you change the glass if it’s disconnected. Your lane navigation system should be working correctly now.  

Recalibrate Your Rear-View Camera

You might need to calibrate your camera if it’s connected, but the lane departure system is still not working. Due to a poor angle on your camera, you might not be able to cover enough ground. 

The lane departure system captures the image of the 164 feet of the ground before properly evaluating your position. Due to a poor angle or positioning, this might not be able to cover enough ground. 

To solve this, you need to take a test drive and adequately measure the correct angle, where the readings are correctly adjusted with the grounds you covered. 

This is easier if you have another person to aid you with the adjustments. One needs to be on the camera, and the other person needs to keep a close look on the monitor to justify the adjustments. 

This also comes down to precisely what type of camera your vehicle uses. Some cameras can be easily moved around in their casing. But some need specialized tools to remove the case before performing adjustments. 

If the camera works perfectly, one person can move in front of the camera while the other verifies. But this can cause some errors in measurements.

Restart To Remove Software Bugs

Aside from the camera, the whole process is calculated by the computer on your BMW. This is a rare instance, but it’s probable because it is ultimately a software-based utility. 

The system and driver assistance might not be updated. This can lead to the software having bugs. A bug in software means despite perfectly working hardware, the system is malfunctioning.

To solve this issue, you need to reset your system. Use the volume-up button to do this on your BMW. Press and hold it for thirty seconds before letting go. Then wait for another thirty seconds before pressing the same button for the second time. This will cause your system to restart.

Performing a master reset should help you deal with any software bugs. If it doesn’t, you need to contact BMW customer care and report this bug. And you will get help convincingly. 

Bypass Country-Specific Speed Limit 

The lane departure warning system works based on the speed limits. It doesn’t work in the USA if your speed is below 40 mph. This is to prevent unnecessary vibration on your steering. 

But this isn’t true for all countries. Different countries have different speed limits. And because the lane departure warning system works only above a specific speed limit, it might not activate at the same speeds everywhere. 

This can lead many users to misunderstand that their lane departure system might not work. So you should learn about the speed limits of your country first if you notice that your lane departure warning system is not working correctly. This will save you some unnecessary trouble.
