Disable Auto Start-Stop in 2024 BMWs: Buttons, Modes & Tips
BMW vehicles are renowned for their performance and driving dynamics. However, in recent years, models across the BMW lineup have been equipped with a fuel-saving technology called an auto start/stop system. This system automatically shuts off the engine when the vehicle comes to a stop and then seamlessly restarts it when you lift your foot off the brake.
While shutting down the engine rather than idling can provide small fuel efficiency benefits, some drivers find the auto start/stop behavior disruptive. The shutdowns and subsequent restarts can be jarring, especially in stop-and-go traffic. This has led many BMW owners to ask: is there a way to disable auto start/stop in 2024 BMW models?
What Exactly Does the Auto Start/Stop System Do?
The auto start/stop system uses sensors to monitor parameters like vehicle speed, brake pedal position, battery charge level and engine temperature. When it determines conditions are right for an engine shutdown, it will automatically cut power when you come to a stop by pressing down the brake.
As soon as you lift your foot off the brake, the engine will restart and you can accelerate as normal. The transition is meant to happen smoothly and seamlessly, although responsiveness varies. BMW states this system can improve fuel consumption by up to 3% in certain driving conditions by minimizing engine idling.
Why Some BMW Drivers Dislike Auto Start/Stop
While the auto start/stop system works as intended, it can cause some abrupt shutdowns and restarts. Drivers may find it disruptive in stop-and-go traffic situations if the engine cuts out every time they reach a stop light or sign.
Other complaints include:
- Decreased responsiveness if engine doesn’t restart quickly enough
- Discomfort from noticeable vibrations when unit shuts on/off
- Cabin cooling concerns since air conditioning stops with engine off
This has led many BMW owners and enthusiasts to seek out ways to disable the auto start/stop function. However, on 2023 and earlier models, there is no permanent defeat method available.
Good News for 2024 Models: There Are Now Ways to Disable
The owner’s manuals for the 2024 BMW model year indicate there will now be auto start/stop disable buttons available across vehicle lines:
- X5 and X7 SUVs: Button placed on lower console near gear shifter
- 7 Series sedans: Located higher on center console closer to gauge cluster
- M Performance models: Disable switch on center console
By pressing this button in 2024 BMW vehicles, an indicator light should illuminate showing that auto start/stop has been manually deactivated for the current drive. While not necessarily permanent, it does allow the system to be quickly turned off as desired by the driver.
Other Ways to Temporarily Switch Off Auto Start/Stop
In addition to the manual shutoff buttons, there are some other techniques 2024 BMW owners can use to temporarily defeat the auto start/stop system:
Shift into Sport Mode
Vehicles equipped with Adaptive Transmission can disable auto start/stop by shifting into Sport mode, which changes the vehicle into a more performance-oriented setting. This can be done by hitting the Sport button on the console and then confirming the mode change on the central display.
Manually Select S Gear
On models with standard Steptronic automatic transmission, pulling back the gear selector puts the vehicle into manual S mode. This has the effect of deactivating auto start/stop as well. Just note that in either case, when you shut off and restart the vehicle it will default back to having auto start/stop enabled.
The Takeaway: More Control and Choices for Drivers
The ability to actively switch off auto start/stop in the new 2024 BMWs, even if just temporarily, is a win for drivers. It provides more flexibility whether you want to prioritize efficiency or performance for your drive. Quick access disable buttons and drive mode selections give owners more control.
While not perfect solutions for those wanting permanent ways to defeat the system, these methods do offer improvements over 2023 and earlier models where auto start/stop had to remain on once enabled. As battery and shutdown/restart technology continues to develop, BMW engineers may eventually provide additional options to cater to driver preferences.
Tips for Driving New BMWs Without Auto Start/Stop
Now that we’ve covered how 2024 BMW owners can disable auto start/stop, here are some suggested best practices for smooth driving without it:
Leave It Off in Heavy Traffic
Frequent stop-and-go traffic with continual shutdowns and noisy restarts is when most drivers report issues with the system. Use your center console button to disable auto start/stop when you first hit congestion so it stays inactive.
Shut Off on Cold Days If Using Seat or Wheel Warmers
To reduce battery drain in frigid winter temperatures, manually deactivate auto start/stop if relying on heated surfaces like steering wheels and seat cushions. Limiting shutdown cycles reduces electrical load.
Drive Gently for Optimal Fuel Economy
Aggressive accelerating and braking significantly reduces mileage as the auto stop/start technology tries to keep pace. Driving smoothly without rapid variations in speed or throttle position maximizes efficiency.
Perform System Updates When Available
As auto start/stop tech matures, BMW will periodically provide enhanced software logic to make the shutdown and restart process less intrusive. Checking for updates helps take advantage of improvements.
The Future: Evolving Methods to Regulate Auto Start/Stop
Looking ahead, BMW will likely continue refining engine shutdown situations and restart timing on models equipped with auto start/stop. More sophisticated sensors and programming should alleviate some complaints over vibration, harshness and disconnected feeling.
There also may be additional ways provided to govern system behavior based on driver preferences. For example, startup setting adjustments that delay restart by certain durations in stop-and-go traffic. Or only enabling auto stop below a certain vehicle speed threshold.
For now manual on/off functionality is a good step toward catering to individual driver needs. But as battery tech improves and the shift to electric vehicles picks up steam, seamless auto start/stop operation will become increasingly important for mainstream integration.
Conclusion: Auto Start/Stop Gives More Control to 2024 BMW Drivers
While fuel saving auto start/stop technology has benefits, the shutdowns and restarts have been an irritant for BMW drivers wanting responsive performance. The lack of permanent defeat options in earlier models also left many owners frustrated.
Fortunately, with the 2024 BMW line providing disable buttons and alternative drive modes, auto start/stop can now be easily switched off according to personal preference. This puts more power in the hands of the driver to determine whether maximum mileage or active dynamics takes priority for any given trip.
So for shoppers eyeing new 2024 BMWs who have found auto start/stop behavior unpleasant in the past, the increased flexibility and simple on/off access should provide some welcome relief. You now have the ability to enjoy the Ultimate Driving Machine with one of its more contentious elements temporarily muted.
