Understanding the BC Button

What is the BC Button?

If you have ever taken a peek inside a BMW vehicle, you might have noticed a button labeled ‘BC’ on the steering column or stalk. While it might seem insignificant at first glance, this button, often referred to as the “BC button,” stands for “Board Computer” and plays a vital role in the overall functionality and operation of your vehicle.

The BC button is designed to offer BMW drivers access to a range of essential vehicle data right at their fingertips. It enables the display and control of various features such as journey data, fuel economy stats, speed limit information, tire pressure monitoring, among other critical parameters. In essence, the BC button acts as a bridge between the driver and the vehicle’s onboard computer, allowing an easy way to access, understand, and manage an array of information about the car’s performance and status.

Where is the BC Button Located in BMW Cars?

The BC button’s location can slightly vary depending on the model and year of your BMW vehicle. However, it is typically located on the turn signal stalk, which is found on the left side of the steering wheel. It’s designed to be conveniently accessible to the driver, enabling them to navigate through the various functions without taking their hands off the wheel. This strategic placement underscores BMW’s commitment to safety, convenience, and driver experience.

In some models, it’s a stalk on its own with an upward and downward movement feature to scroll through the different functions. On other models, it is a button at the end of the turn signal stalk. In either case, the BC button’s purpose remains the same: to offer an intuitive, user-friendly interface for drivers to access important vehicle data and features.

Exploring the Functionality of the BC Button

The BC button is akin to a miniature command center, providing drivers access to a host of valuable information and functionality. Let’s unravel each of these features one by one.

Trip Computer

The trip computer is perhaps one of the most commonly used features of the BC button. By pressing the BC button, drivers can quickly access important information about their journey. This includes details such as the distance covered during the trip, the average speed, and the estimated time of arrival (ETA) at the destination if navigation is active.

Understanding these parameters can help drivers plan their journey better, make timely decisions, and even improve their driving habits. For example, the data on average speed can provide insights into how changes in driving style can affect fuel economy.

Journey Data

Beyond the confines of a single trip, the BC button provides an overview of journey data. This includes details like total distance covered since the last reset, the average fuel consumption, and the average speed for the duration. This feature is particularly useful for tracking long-term trends in driving behavior and vehicle performance.

Fuel Consumption

One of the most critical aspects the BC button allows drivers to monitor is the vehicle’s fuel consumption. It offers real-time data on current fuel consumption as well as the average fuel consumption over a certain period. This information is crucial for drivers looking to maximize their vehicle’s fuel efficiency or simply keep tabs on their fuel expenditure.

Speed Limit Info

Some newer BMW models equipped with Speed Limit Info technology use a camera mounted in the windshield to identify speed limit signs. The BC button allows drivers to access this information, displaying the current speed limit in the driver information display. This feature contributes significantly to driver awareness and safety.

Check Control Messages

BMW’s Check Control system monitors various systems and functions in the vehicle. If the system identifies a potential issue, a Check Control message will appear in the vehicle’s information display. The BC button allows drivers to scroll through and acknowledge these messages, helping them stay informed about their vehicle’s health and maintenance needs.

Tyre Pressure Monitor

Last but certainly not least, the BC button provides access to tire pressure monitoring information. It allows drivers to check the tire pressure status without the need for any additional equipment, ensuring optimal tire health and safety.

These are just some of the functions available through the BC button, each contributing towards making your drive safer, more informed, and ultimately more enjoyable. But like all technology, there may be times when you face issues or difficulties.

Common Issues and Troubleshooting

While the BC button is designed to offer seamless functionality, there can be instances where drivers might encounter problems. Understanding these issues and knowing how to troubleshoot them can help ensure uninterrupted access to the vital information the BC button provides.

Common Issues with the BC Button

One of the most common issues that BMW drivers report with the BC button is that it sometimes fails to respond or displays incorrect information. This can be caused by various factors, such as a software glitch, a faulty stalk, or issues with the vehicle’s onboard computer.

Another problem often reported by users involves the inability to scroll through the menu or the BC button sticking when pressed. These problems could be due to mechanical issues within the stalk or, in some cases, could be a symptom of a broader electrical issue within the vehicle’s system.

Troubleshooting the BC Button

Before jumping into complex solutions, start with simple troubleshooting steps. The first approach should be to perform a soft reset of the onboard computer. You can do this by turning off the vehicle, removing the key, and waiting for a few minutes before restarting the vehicle. This procedure can often resolve minor software glitches that may be interfering with the BC button’s functionality.

If the issues persist, consider consulting the vehicle’s user manual or seek assistance from a professional BMW technician. It’s essential not to ignore persistent issues as they could indicate more serious underlying problems that need immediate attention. In certain cases, a software update or a hardware replacement might be required to restore the BC button’s proper functioning.

Understanding and addressing common issues with the BC button will not only improve your user experience but also enhance your vehicle’s overall health and performance.


In the modern era of automotive technology, a simple push of a button can reveal a world of information and control at your fingertips. The BC button, a seemingly small feature in the intricate web of BMW’s advanced vehicle interface, plays an outsized role in augmenting the overall driving experience. It offers a bridge between you, the driver, and a wealth of vital information about your vehicle’s status and performance.
