Ever noticed the “BC” button on your BMW’s indicator stalk and wondered what it actually does? You’re not alone. Many BMW owners aren’t sure what the BC button is for or how to make the most of it.
This article breaks it all down—what the BC button is, what it controls, and how you can use it to get more info from your car’s onboard system. Let’s dive in.
What Is the BC Button on a BMW?
The BC button on a BMW stands for “Board Computer.” It helps you scroll through different types of driving information on your instrument cluster. You’ll usually find this button at the end of the turn signal stalk, and it gives you access to a range of data about your car’s performance and status.
This includes things like:
- Average fuel consumption
- Range (how far you can go with remaining fuel)
- Average speed
- Outside temperature
- Digital speedometer (on some models)
- Real-time fuel economy
- Trip data (distance, time)
It’s a simple but powerful tool that makes your drive smarter and more informed.
Where Can You Find the BC Button?
You can find the BC button on the left stalk behind the steering wheel—usually the same one you use for turn signals. It’s a small push-button on the end of the stalk. Once you know where it is, it becomes second nature to use it.
BMW places it here to keep it easy to access without taking your hands far from the wheel. You can safely toggle through your driving stats while on the move.
How Do You Use the BC Button?
To use the BC button, simply press it to scroll through the different onboard computer displays on your dashboard. Each press will cycle through one data screen at a time. Hold it down in some cases to reset data like average fuel consumption or trip time.
Step-by-step instructions:
- Turn on your ignition or start the car.
- Look at the screen in your instrument cluster (behind the steering wheel).
- Press the BC button once to scroll to the next information display.
- Keep pressing to cycle through all available stats.
- To reset data like average consumption, hold the button down while on that screen.
And that’s it. You don’t need to dive into any menus. Everything is right there, one press away.
What Does Each BC Button Display Mean?
Let’s break down the common data types the BC button lets you see:
| Display | What It Means |
|---|---|
| Average Fuel Consumption | Shows how many liters or gallons your car uses per 100 km or per mile on average. |
| Range | Estimates how far you can drive before refueling based on current fuel level and driving habits. |
| Average Speed | Displays your average driving speed since the last reset. |
| Outside Temperature | Tells you the current temperature outside the car. |
| Trip Distance | Measures how far you’ve driven on your current trip or since the last reset. |
| Trip Time | How long you’ve been driving since starting the car or last reset. |
Why Should You Use the BC Button?
The BC button helps you stay informed and optimize your driving habits for better fuel economy and efficiency. It’s a simple feature that gives you real-time feedback. Whether you’re trying to save fuel, plan your next gas stop, or track trip details, this button gives you instant answers.
Real-world benefits of using the BC button:
- Fuel Savings: By monitoring fuel economy and adjusting how you drive, you can save money on gas.
- Trip Planning: Helps estimate arrival times and plan fuel stops more accurately.
- Safe Driving: Outside temp alerts you to icy conditions or extreme heat.
- Convenience: No need for separate apps or tools—everything is on the dash.
Common Mistakes When Using the BC Button
Even though it’s simple, a few mistakes can limit your use of the BC button:
- Not resetting data: Forgetting to reset trip data can lead to inaccurate averages.
- Ignoring the range: Not watching fuel range can lead to running low unexpectedly.
- Misreading metrics: Make sure you know whether your car displays MPG, L/100km, or km/L depending on your region.
Once you get the hang of it, you’ll find it’s a great tool to keep track of everything that matters while driving.
Can You Customize BC Button Settings?
On newer BMWs, yes—you can customize what info shows up when using the BC button via the iDrive menu. You can choose which displays you want to see and which ones to hide.
Just follow these general steps:
- Go to your iDrive menu.
- Navigate to “Settings” > “Instrument Cluster” or “Displays.”
- Select or deselect the BC data you want to appear.
This way, your BC button only cycles through the stats that matter to you.
BC Button Not Working? Here’s What to Check
If your BC button isn’t working, check for basic issues like a stuck button or software glitches first. It could be a simple fix, or it might need a trip to the mechanic.
Quick troubleshooting tips:
- Restart the vehicle—sometimes it resets the system.
- Make sure your instrument cluster is functioning properly.
- Try holding the button for a few seconds instead of tapping.
- Check for blown fuses or wiring issues behind the stalk.
If none of these work, it might be time for a diagnostic scan or help from a professional.
