Do you have problems with the electronic system in your BMW? BMWs are considered some of the best cars in the market in terms of technology and performance, but like any car of this generation, they are controlled by electronics. If something is not working as expected, like your iDrive system is not responding as it should, the dashboard is blinking, or the battery dies, it can be inconvenient at best and affect your vehicle’s performance at worst. Here is a list of some of the most common problems in electronic systems of BMWs, and how you can deal with them.
Effective Solutions for BMW Electronic Problems
- Solving Battery Drain and Charging Issues: A professional voltage test can reveal whether the battery needs to be replaced or not. BMW batteries have an average lifespan of four to six years. If your battery dies often, then your alternator should also be checked to see if it is charging the battery.
- Fixing iDrive System Issues: Pressing the volume/power button for at least 30 seconds can help to reset the system and eliminate minor issues. It is also important to check for software updates and get them installed from a certified BMW service center, as this would also enhance the system’s performance. If the iDrive is still unresponsive or slow, the internal hard drive may need to be replaced.
- Resetting Faulty Electronic Steering Lock: Switching off and turning on the battery can sometimes help to fix the faulty electronic steering lock. If the problem continues, a technician can check the steering column module and either update or fix it. Many BMW car owners have decided to install an ESL emulator to get rid of constant steering lock issues.
- Addressing Dashboard Warning Lights: You should take your vehicle to a professional for a scan which will identify the exact issues that are causing the warning lights to remain on. If the problem is due to a bad sensor or loose connection, then fixing or replacing the problematic part should remove the warning. In some cases, a software reset is called for to clear up false alarms.
- Fixing Parking Sensor and Backup Camera Problems: Sometimes minor detection problems can be solved by cleaning the sensors or the backup camera lens. If the issue continues, a mechanic should check whether the wiring of the sensor is damaged. BMW often rolls out updates for the software that makes parking assist systems more accurate and less prone to failure.
- Transmission Control Module Glitches: If your BMW’s transmission shifts roughly, takes time to change gears, or goes into ‘limp mode,’ it may be due to the transmission control module. You can use a scanner to look for any error codes on the car. Sometimes minor problems with the TCM can be solved by a software update. If the module is defective, however, then it has to be repaired or replaced.
- Fixing Failed Lights: Sometimes, the headlights or the tail lights may flicker or fail to turn on fully in BMWs. This is commonly attributed to bad wiring, faulty control modules, or bad LED components. The first step is to check the bulb connections since poor connections due to loose or corroded contacts can lead to flickering. If your BMW is equipped with adaptive headlights, then the problem might be in the control module, which may require reprogramming or replacement.
