Software updates are supposed to enhance the performance of your BMW and even introduce new features in it, but when something goes wrong with the software update, it can cause a number of problems ranging from flickering screens to a stalling engine to total system failure. If you are having issues with your BMW after an update, or if the update process was interrupted, this article is for you.
What Does a BMW Software Update Do?
BMW updates are performed in order to enhance the car’s infotainment system, navigation, engine control units, and driver assist features. These updates ensure that your car operates smoothly, safely, and efficiently. While most of the latest BMW models can receive updates over-the-air (OTA), older models may have to be taken to a service center to be updated through the BMW diagnostic tools. In either case, the idea is to ensure that your car gets the latest upgrades or features for better performance.
Common Signs of Software Update Failure
- Warning Lights Stay On: There are several warning lights on your dashboard and if any of them stay on even after a reset, then this is a clear indication that something is wrong with your BMW. Warning lights can stay on if the update is not completed properly or if there is an issue with the control unit software.
- Loss of Functions: Does your radio, backup camera, parking sensors or even your climate control buttons not respond or function as they used to? Sometimes some of these systems may fail to work as expected or may shut down due to a failed software update.
- Performance Problems: You might notice that your BMW vibrates, shifts abnormally, or fails to start. Since most of the car’s operations are managed by software, any glitch in the update process affects how the engine, the transmission, or the fuel system will work.
- Error Messages: In some cases, you might start seeing error messages such as “software update failed” and “control module not responding,” which are indicators that the update process was not successful.
How To Solve BMW Software Issues
- Diagnostic Scan: The first step in the process is to perform a comprehensive diagnostic scan of the car with BMW compatible software. This process enables your technician to diagnose which particular modules are faulty, if firmware is outdated, or if there are other electronic issues. It can read error codes as well as live data from any of the vehicle’s electronic control units, which makes it easier to determine what is wrong.
- Battery and Voltage Check: It is recommended to check the battery status and voltage before proceeding to any software reset or update. If the voltage drops during reprogramming, it can interfere with the update and worsen the condition of control modules.
- Software Reprogramming or Update: The next thing that has to be done is to reprogram or update the affected module(s) using official BMW software platforms if the issue is determined to be of software origin. These updates may correct existing glitches, enhance speed, or reinstate features that have been disabled. The update must be installed accurately to prevent the control units from becoming bricked.
- Testing and Calibration: It is important that after the reprogramming, each of these systems should undergo testing and calibration. This helps to check if all aspects of the car ranging from engine management to the navigation or the Infotainment systems are working correctly.
