Auto Start-Stop Disabler with Seatbelt & Speed Warning Eliminator

For BMW U Series (2023+ with Curved Display)

The Auto Start-Stop Disabler is an all-in-one plug-and-play device designed for BMW U Series vehicles (from 2023 onwards) equipped with curved displays. It allows you to permanently disable the auto start-stop system and suppress seatbelt and speed warning alerts — all without coding or permanent vehicle modifications.

Once installed, the device remembers your preference, so you no longer need to manually deactivate these functions every time you start your car.

What is the auto start-stop system?

The auto start-stop system automatically switches off the engine when the vehicle comes to a stop (for example, at traffic lights or in congestion) and restarts it when you move off again. The aim is to reduce fuel consumption and emissions, particularly in urban driving.

While this technology can be beneficial in some situations, many drivers find it intrusive and unpleasant to use on a daily basis.

Why disable auto start-stop?

Although manufacturers highlight fuel savings and environmental benefits, the system also comes with drawbacks that can affect driving comfort and long-term ownership:

1. Jerky or delayed restarts, especially when pulling away in traffic
2. Reduced refinement, which can detract from the premium driving experience BMW is known for
3. Increased strain on components such as the battery and starter motor
4. Potentially higher maintenance costs over time

BMW allows the system to be switched off manually, but the setting is not saved. On newer BMW models, permanent deactivation through coding is no longer possible — making a dedicated disabler the only practical solution.

What does this device do?

This Auto Start-Stop Disabler connects seamlessly to the vehicle’s CAN bus system and allows you to control multiple functions at once using simple button presses. Installation is quick, completely reversible, and requires no specialist tools or technical knowledge.
