Diagnostic Actions to Diagnose the Issue

Check for Software Updates

BMW has been releasing updates of iDrive to fix bugs and improve compatibility. The latest version is checked using the software update feature.

Restart the System

Perform a soft reset. In most BMWs the volume/power knob must be held down for 20-30 seconds until the screen reboots. This is sometimes just a clear-up procedure.

Examine Hardware Connections

Unless uncomfortable inspect below the dashboard or at the back of the infotainment screen to check for loose wires or damage.

Test Functionality

Try other features such as Play Radio, use Bluetooth or use the navigation. When certain features are functioning and others are not then this can help determine whether the problem is software or hardware related.

Measure Environmental Conditions

Record when problems occur such as when the car has been in the sun or in the cold. Intermittent failures might be caused by overheating and condensation.

Solutions and Troubleshooting Hints

Software Update or Reset

Install new applications on the official BMW site or your Connected Drive portal.

To perform a hard reset, unplug the negative battery terminal for a few minutes although only if you are sure of your automotive DIY skills.

Consult the Owner's Manual

Search for infotainment error codes or behaviors. Some codes provide workarounds or trip-to-dealer instructions.

Use Diagnostic Tools

Hardware faults or software bugs can be identified using BMW's proprietary scanner or third-party OBD-II readers.

Professional Consultation

If the problem persists then visit a certified BMW service center. Numerous screen or module problems demand training and tools.
