What does the Audi A6 P310B fault code mean when the car is running normally?
1 Answers
The Audi A6 displaying the P310B fault code indicates insufficient low-pressure fuel supply pressure, usually caused by a clogged fuel filter or a faulty fuel pump motor. Below are detailed explanations: 1. Fuel Filter: The fuel filter is one of the "three filters" commonly used to remove impurities from automotive fuel. Under normal usage, it should be replaced every 30,000 kilometers. If the fuel contains a high level of impurities, the replacement interval should be shortened accordingly. Generally, it is recommended to replace it every 20,000 kilometers. 2. Fuel Pump Motor: The fuel pump motor consists of the motor body, front cover, and output drive shaft. Its function is to draw fuel from the fuel tank, pressurize it, and deliver it to the fuel supply line, working in conjunction with the fuel pressure regulator to establish a certain fuel pressure.
