But, does stop-start damage your engine? PLENTY OF OPINIONATED writers will tell you how stop-start is all about carmakers gaming the system in lab-based fuel economy tests, and to some extent it is, but there’s more to stop-start than that. Sit back and let uncle Isaac learn you… What’s the history of stop-start?
Stop/Start Technology† automatically stops and starts the vehicle’s engine under certain conditions. By turning off the engine when not needed, Stop/Start Technology can help improve fuel efficiency, thereby reducing greenhouse gas emissions (compared to the same vehicle with Stop/Start Technology not in use).

Dear all, I repentantly acquired a BMW 520d F11 Touring (184hp) and, for that reason, I am new to this forum. About 2 months ago a very annoying problem started. After driving some km (>50), a warning of "low battery" would appear on the front panel. After this warning, if I stopped the car, I would have to wait about 1 hour to start it again.

The stop/start feature on your BMW may not be working properly for a variety of reasons. One possibility is that the battery is not properly charged. Another possibility is that the stop/start sensor is dirty or damaged. If the sensor is dirty, you can try cleaning it with a soft cloth. If the sensor is damaged, you will need to replace it.
I don't remember the start/stop feature on my former 2016 330e nor my current 2018 530e. Yestechnically it is there but the electric motor keeps running so the car does the traditional "creep" at a light (e.g.) unless one activates autohold or keeps one's foot on the brake.
Yet, with it turned off, the start-stop improved fuel economy by 9.5%. Additionally, the Jaguar and BMW models tested alongside the Mini also cut their fuel use by roughly 10% using start-stop tech. In short, stop-start systems can help you save fuel, and they won’t damage your engine.
Auto Start Stop function. Red lights, traffic jams, road works - in everyday driving situations there are countless instances where the engine is idling, unnecessarily burning fuel. The Auto Start Stop function, a BMW EfficientDynamics technology, makes this a thing of the past. The Auto Start Stop function switches off the engine when the
A lack of fuel pressure or fuel volume can easily lead to engine stalling. Common culprits include a faulty fuel pump or fuel pump relay. A clogged fuel filter or bad fuel pressure regulator is also common on return-type fuel systems. Another often overlooked problem is the vehicle simply being out of fuel.

John MS said: If the question is whether the starter will wear faster with auto stop start on than off the answer is obviously yes. It's duty cycles. That begs the question of how long before the starter wears out. My guess is it will last for longer than you own the car. 0Z2AeY1. 565 610 964 476 499 482
