What happened when the BMW 5 Series turned itself off when refueling?

Hello: the question you asked is like this. When the vehicle is driving at a low speed, the flameout can be divided into two situations. If the flameout is in the state of lifting the accelerator pedal and sliding, it is caused by the abnormal operation of the engine idle speed control system. Therefore, it is recommended that you check whether the engine idle speed is normal. If the idle speed is too low, it may be that the throttle is unstable due to excessive carbon deposition, so it is necessary to check the carbon deposition on the throttle and other components that affect the engine idle speed. In another case, if the engine flameout occurs during refueling, it should be caused by circuit problems, such as virtual connection, and then it may be that the vehicle bumps and the engine vibrates, resulting in sudden flameout or sudden fuel cut-off. Therefore, this phenomenon has a high probability of accidental contact in the line. I suggest that you focus on the on-site inspection of vehicles according to the above reasons.
