Audi A4L parking automatic flameout reason explanation: Low engine temperature: Fuel is also not easy to volatilize and not easy to vaporize. If the carbon deposits in places such as the oil circuit and intake tract are serious, these carbon deposits will first absorb some fuel vapor, which can easily cause the mixture entering the cylinder for combustion to be too lean, and may also cause unstable idle speed, flameout immediately after ignition and other phenomena. At this time, if you ignite several times, the carbon deposits are full of fuel vapor, and the mixture entering the cylinder for combustion meets the standard, and it can also start. Fuel pump failure: It may suddenly get stuck or other faults may cause the fuel pump to lack rotation or stop, resulting in insufficient fuel supply and causing flameout. The fuel system pressure is too low, such as low oil pump pressure, pipeline oil leakage, small supply current, fuel pressure regulator damage, etc., resulting in insufficient fuel supply. The fuel injector is blocked or leaking, resulting in poor atomization, thus insufficient fuel supply, causing flameout.
