How much fuel does one bar on the fuel gauge represent?

According to different vehicle models, the amount of fuel represented by one bar on the fuel gauge may vary. Taking the SAIC Volkswagen Passat as an example, the Passat has a fuel tank capacity of 66 liters, and the fuel gauge is divided into 8 bars, with each bar representing 8.25 liters. There are generally two types of fuel gauges: one is a mechanical needle-type fuel gauge, and the other is an electronic fuel gauge. The mechanical needle-type fuel gauge is the traditional type, which senses the fuel level in the car's fuel tank through a fuel float and a pull wire, then feeds back to the instrument panel, displaying the remaining fuel via a needle. The electronic fuel gauge operates through electronic devices in the fuel tank and the digital processing system of the car's computer, displaying information such as remaining fuel and driving range on the central control screen or instrument panel.

What Causes Engine Fault Codes?

Engine fault codes can be caused by issues such as carbon buildup on spark plugs and poor fuel quality. The specific reasons are as follows: Carbon Buildup on Spark Plugs: After some time of use, the engine accumulates carbon deposits, which can lead to engine damage, difficulty starting, poor acceleration, excessive engine noise, and other issues. The accumulated heat can cause irregular ignition, resulting in engine knocking. In such cases, the engine fault light will illuminate. Poor Fuel Quality: Substandard fuel quality. Some drivers may notice the engine fault light turning on immediately after refueling, which is usually due to filling up with low-quality fuel at non-standard gas stations.
