The Start and Stop system has two indicators on the dashboard: a standard light confirming system availability and a crossed-out version indicating that the system is unavailable.
So, how can you tell if the system is faulty?
How do you diagnose the issue?
And how do you reset the warning lights?
Are you looking for a car scanner ?

Why does the Start & Stop warning light stay on?
Since the system has two indicators to display its status, one of them will always be visible on the dashboard.
Is it dangerous to drive with the Start and Stop warning light on?
Driving with a faulty Start and Stop system is not dangerous. The system only turns off the engine when the car is idling or moving at a very low speed (up to 15 km/h), such as at a red light, in traffic jams, or in a drive-through queue. The starter will not cause the engine to stall while driving, even if the Start and Stop system is malfunctioning.
The only potential risk when the Start and Stop system is not working is related to the battery. Since the Start and Stop system is part of the vehicle’s electronic systems, it is powered by the battery.
A Start and Stop system that does not activate may be a sign of a failing battery, which can lead to further issues.
Is a warning light a problem for the vehicle inspection?
Since Start & Stop malfunctions do not pose a safety risk, a faulty system will not cause a failure during a vehicle inspection.
So, if your vehicle inspection is approaching and your Start and Stop system is not working, there is no need to worry—it will not be taken into account. However, if the issue is caused by a battery problem, that could lead to a failed inspection.
Repairing the Start and Stop system
Since at least one of the warning lights is always on, how can you tell if the system is faulty?
A simple sign is if your Start and Stop system does not activate when it should. For example, if you are stuck in traffic and the system does not engage, that is a bad sign.
But the key question is why? The repair process will be different depending on whether the issue stems from a low battery voltage or a failing starter motor.
The best approach is to run a vehicle diagnostic using a Car Diagnostics Scanner. This will allow you to clearly identify the issue and carry out the necessary repairs.
Conclusion
When the Start and Stop system no longer activates, the most challenging part is not fixing the issue, but identifying its cause. This is why performing regular diagnostics on your vehicle helps detect faults as early as possible.
