Is auto start-stop technology bad for the engine? ASST reduces fuel consumption by shutting down a vehicle’s engine when idling. The technology has been around for more than 20 years. It has been present in European and Asian vehicles for a while now. It has recently become available in new models from several automakers in the US as well. But will low oil pressure cause vehicle not to start? Definitely, it would. When your car engine is not getting enough lubrication as required, it could develop faults, which can lead to your car not starting. As you may have heard, oil is the “blood” of every engine; hence, it is recommended by automakers that you change the oil in your The start/stop feature of your car is designed to save fuel and lower vehicle emissions. AAA’s engineering department did some tests and found that fuel savings have been as high as five percent. Regarding extra wear and tear, so far tests have shown no significant change in battery or starter motor life. See how the car runs on the highway, anything below 78-79C generally means tstat needs replacing. Since the problem goes away with restart, it sounds electrical. That always leads me to check the MAF's (and when you unlock the OBC, you can do the dynamic MAF test, #4, option #2) and the 4 CPS. Regards, Jerry. 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. I never had rough idle on start up until after BMW preformed recall #2017-470 Engine PCV blow-by-heater. Now engine shakes for 1st 10 to 15 seconds with RPM rising and falling. Then everything works itself out and the car runs great. My car is a 2011 BMW 328XI with only 42,000 kms. Called dealer and they said they doubt it is related to work. If you recently purchased Remote Engine Start, but it is not shown in your vehicle, this could be due to technical restrictions (e.g., low battery, low outside temperature, etc.) or you may need to complete several drives before the feature is shown.

Volkswagen of America first incorporated stop-start technology in 2017 on its new Atlas SUV and the redesigned Tiguan. Doug Skorupski, a powertrain strategy manager at VW, explains the feature. "As you're actually releasing the brake pedal, the system is able Then, try turning the engine over with a breaker bar. If it moves, you may be able to salvage the engine. If not, you’ll have to pull it apart and rebuild it. If your engine is hydrolocked, take out the spark plugs right away and crank the engine over. The water will pump out of the cylinders, releasing the hydrolock. This system assists the driver by automatically setting and releasing the brake, such as when moving in stop-and-go traffic. The vehicle is automatically held in place when it is stationary. On inclines, the system prevents the vehicle from rolling backward when driving away. Automatic Hold remains activated during the engine stop brought about 8VwmNKl.
