How to Restart BMW's On-Board Computer?
2 Answers
The method to restart BMW's on-board computer is: press and hold the volume button for about ten seconds. The on-board computer is located below the instrument panel, displaying daily information such as gear position, time, remaining range, outside temperature, total vehicle mileage, and single-trip mileage. The display page content can be set using the control buttons on the right side of the steering wheel. BMW models include: BMW X1, BMW 3 Series, BMW X5, BMW X6, BMW X7, etc. Taking the 2021 BMW X1 as an example, it is a compact SUV with body dimensions of: length 4565mm, width 1821mm, height 1620mm, and a wheelbase of 2780mm.
Rebooting the BMW onboard computer sounds complicated but is actually quite simple—I've done it myself several times. Over time, the onboard computer can occasionally freeze, causing abnormal dashboard displays or other glitches. Here's the tried-and-true method I follow: First, find a safe spot to park, turn off the engine, and remove the key to prevent accidents. Then, pop open the trunk, locate the battery compartment, and use a wrench to loosen and disconnect the black negative terminal cable. Wait at least 10 minutes to let the system fully discharge and clear its cache. After that, reconnect the cable and tighten the screw. Upon restarting the engine, the system will reset and usually resolve minor issues. This method is straightforward, cost-effective, and saves a trip to the dealership. Just remember to wear insulated gloves during the process and avoid touching other metal parts to prevent electric shocks. If problems persist, it's best to have a professional inspect for potential issues like aging wiring. You can also perform this reset as a preventive measure during routine maintenance. All you need is a basic 10mm wrench—easy to handle.
