When the oil light comes on while the temperature is normal in a new Jetta, it indicates an abnormality in the lubrication system. Reasons for the oil light illuminating: For Jetta vehicles, when the engine lubrication system's oil light turns on or flashes while the oil level check shows normal, it is necessary to inspect the oil pressure. This helps determine whether the oil pump's performance and the oil pressure sensor are functioning properly. If not, repairs or replacements should be carried out accordingly. It is recommended to visit a repair shop for a thorough inspection of the lubrication system. Solutions for the oil light coming on: The oil light issue can be resolved by: adding oil to the engine; changing the engine oil; inspecting and repairing the cooling system; conducting engine maintenance; checking the engine crankshaft; replacing the pressure relief valve or its spring; or replacing the oil sensor, pressure gauge, or related circuits.

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 are the effects of a car key getting wet?

The car key does not have waterproof function, so if the key falls into water or gets wet, it is necessary to deal with it in time to prevent damage caused by corrosion and oxidation of the internal circuit board due to prolonged exposure to water. The following are the methods to deal with a wet car key: 1. First, pull out the mechanical key of the remote key, then turn the logo of the key upward and pry open the back cover of the key. 2. Remove the key battery first to prevent short circuit of the internal circuit board due to the key being powered. 3. Remove the entire back cover of the key, take out the circuit board, use a paper towel to absorb the moisture on the circuit board and the front and back covers of the key, and then use a hot air blower to dry the circuit board and the key cover to prevent oxidation of the circuit board. 4. After completing the work of dealing with the wet key, install it in the reverse order of disassembly to reset it.

What is the appropriate gear for novice drivers?

Gear selection is determined by vehicle speed. Novice drivers typically use 4th gear, but in practice, gear shifting should be based on actual speed. The relationship between vehicle speed and gears: Start in 1st gear, shift to 2nd after acceleration. Shift to 3rd when speed reaches between 20 to 25, then to 4th when accelerating to around 35 to 40. Shift to 5th gear when speed reaches approximately 60. Proper gear selection can save fuel: Manual transmission vehicles are fuel-efficient because their transmission efficiency is relatively high, reducing power loss. Driving a manual transmission car requires higher driving skills. Only by selecting gears reasonably and timely can true fuel efficiency be achieved.
