Is Leaving After Scratching a Car Considered Hit-and-Run?

What to Do When a Vehicle Stalls Due to Road Waterlogging Caused by Heavy Rain?

You should immediately exit the vehicle and move to higher ground. Here are some precautions for driving in heavy rain: 1. Address visibility issues promptly while driving: Using headlights in rainy conditions can create a blinding glare, so switch to fog lights instead. If fog forms on the windshield, turn on the air conditioning's cooling function and direct cold air toward the windshield to quickly clear visibility. If fog appears on the rear windshield, activate the rear defroster to eliminate it as soon as possible. If the wipers are not clearing water effectively, applying car wax to the windows can create a wax film on the glass surface, improving visibility. 2. Navigate waterlogged areas at low speed and high RPM: When driving through waterlogged areas, use a low gear, maintain a slow speed, and steady the throttle. Avoid stopping, shifting gears, or making sharp turns midway. Even in neutral, keep revving the engine to maintain exhaust pressure higher than the water pressure, preventing water from flowing back into the exhaust pipe if the car stalls, which could damage the exhaust system. Avoid driving if the water depth exceeds the center of the wheels or the exhaust pipe to prevent engine stalling. 3. Post-rain inspection: This helps identify potential issues early. Pay special attention to checking for water accumulation in the intake vents near the engine compartment and cabin divider, as well as in the grooves on both sides of the wheel wells. If water is found, rinse the intake vents with clean water and clear the drainage channels to ensure optimal vehicle performance. 4. Avoid low tire pressure: When driving in rainy conditions, maintain a tire tread depth of at least 4 mm to prevent issues like veering, fishtailing, or increased braking distance. 5. Maintain a safe following distance: The braking distance on wet roads is approximately three times that on dry roads. Therefore, always keep a safe distance from the vehicle ahead—at least two car lengths, depending on speed—to avoid rear-end collisions. If the vehicle behind is following too closely, turn on the hazard lights to alert them.

What Causes the Engine Malfunction Light to Illuminate on the Dashboard?

The illumination of the engine malfunction light on the dashboard indicates a fault in the vehicle's engine. Possible causes for the engine malfunction light include turbocharging issues, substandard exhaust emissions, clogged fuel injectors, throttle position sensor problems, and in some vehicles, transmission system faults that are also indicated via the engine malfunction light. Specific causes are detailed below: Sensor Issues: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors can trigger the engine malfunction light when they are damaged, have poor connections, or experience signal interruptions. This prevents the vehicle's ECU from accurately obtaining engine data. Turbocharging Issues: Problems with the intake turbocharging pipeline or turbocharger can also cause the engine malfunction light to illuminate. The most common issue is a damaged turbocharger, often accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Exhaust Issues: Faults in components like the rear oxygen sensor, catalytic converter, exhaust camshaft, and bearings can lead to the engine malfunction light turning on. The most frequent cause is a faulty catalytic converter, which can result from using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or issues with the engine's fuel supply system. Anti-Theft System: If the vehicle's electronic anti-theft system malfunctions or if the anti-theft controller does not match the engine's electronic controller, the anti-theft system can prevent the engine from operating normally and trigger the engine malfunction light. Precautions: If this fault occurs, the vehicle should not be driven. It is necessary to check whether the coolant level is low, whether the engine oil requires replacement or is insufficient, clean the throttle body and intake passages, inspect the spark plugs for proper function, and verify the condition of the ignition coils. The vehicle should not be driven until these checks are completed.

How to Adjust the Instrument Panel Brightness on the RAV4?

The RAV4's instrument panel does not have a brightness adjustment setting. The Auto mode allows the instrument panel to illuminate along with the external lights. Below are specific reasons why the car's instrument panel lights may not be working: 1. Due to a broken power supply wire for the instrument panel, or faults in the circuit and related components. 2. A blown fuse in the instrument panel's power supply causing the lights not to work. 3. Damaged instrument panel lighting bulbs or a faulty brightness switch. 4. Malfunction in the integrated instrument control unit or optical sensor system. 5. Generally, if individual lights are not working, it indicates that the fuse and wiring are not the issue.

Audi A4L New Car Engine Noise is Loud

Audi A4L new car's engine during the break-in period may produce some noise because it is not fully broken in. If the noise is quite loud, it is advisable to consult a 4S dealership to ensure the car operates normally during the break-in period, preventing any abnormal engine conditions that could lead to excessive wear and affect the engine's normal service life. During the break-in period, avoid prolonged high-speed driving as it causes the engine to operate at high RPMs, which can easily lead to engine overheating and exacerbate abnormal wear. High-speed driving should not exceed three hours; necessary stops for rest allow the engine to fully dissipate heat.

Can a 4S shop detect odometer tampering?

4S shops can detect odometer tampering. They can determine whether the odometer has been rolled back based on maintenance records and professional diagnostic computer tests. For some automatic transmission models, the diagnostic computer can also check the transmission mileage to verify if the odometer has been tampered with. Odometer tampering is a common phenomenon in the used car market, as consumers purchasing used cars often place high importance on the vehicle's mileage, leading to such practices. Generally, a diagnostic computer connected to the OBD interface can be used to roll back the odometer, but some models require specialized computers matched to the specific vehicle brand. For example, certain German car brands require their own brand-specific diagnostic computers for odometer adjustments.
