On the BMW 4 Series F32, the factory Start/Stop system can quickly become frustrating in daily driving: unwanted engine shut-offs in traffic, vibrations on restart, and a slight delay when pulling away.
Our electronic module permanently solves this issue:
→ The Start/Stop function is automatically deactivated at every ignition start — no button press required.
Our module remembers your latest setting at every startup. Once installed, simply deactivate your car’s Start/Stop functionality, and it will remain disabled until you decide otherwise.
Prefer to return to factory behavior?
→ Simply press your Start/Stop button again. No coding, no permanent modification, and no trace left on the vehicle.
Free shipping – 1-year product warranty
While intended to reduce fuel consumption, the Start/Stop system can place additional strain on key components such as the battery, starter, and turbocharger, particularly in urban driving. It may also cause noticeable vibrations and disrupt the smooth, refined driving experience expected from a BMW coupe.
With this module installed, the engine remains ready at all times, restarts are smoother, and the vehicle feels more responsive and enjoyable in everyday use.
