EPC warning light solutions: 1. Use qualified fuel and clean the throttle body; 2. Remove carbon deposits from related parts; 3. Rewrite ECU-related data. EPC stands for Electronic Power Control, and the illumination of the warning light indicates a potential fault in the electronic throttle system, which may affect the normal operation of the vehicle. Reasons for the EPC warning light: 1. Intake system faults, such as leaks or blockages; 2. Dirty throttle body or excessive carbon deposits; 3. Use of substandard fuel; 4. Abnormal cylinder pressure or poor operating conditions; 5. Valve faults, sticking, or carbon deposits; 6. ECU faults; 7. Sporadic faults or false alarms.

What to Do When the Car Fuel Pump Fails and the Engine Won't Start?

If the fuel pump is damaged and the engine won't start, the fuel pump must be replaced. The reasons for fuel pump damage are as follows: 1. Insufficient fuel in the tank: When the fuel level warning light on the dashboard lights up, there is approximately 7 liters of fuel remaining in the tank. At this point, the fuel level is too low, preventing the fuel pump motor from receiving adequate cooling and lubrication, which can cause the motor to overheat or even stop. 2. Poor fuel quality: When fuel quality is poor, the fuel tank may contain various impurities or foreign objects. The fuel is sucked in through the filter screen at the bottom of the pump and delivered to the engine. During this process, large particles are blocked by the filter screen, while small particles are sucked into the fuel pump motor, inevitably accelerating wear and tear and causing damage. 3. Long-term neglect of fuel filter replacement: If the fuel filter is not replaced for a long time, the fuel supply system can become severely clogged, making it difficult for the fuel pump to deliver fuel. Prolonged operation under high load conditions can lead to fuel pump damage.

Are There Risks in Selling Points? What Issues Should Be Noted?

Certainly, there are risks. Drivers selling their own driving license points are already violating the "Public Security Administration Punishment Law." Buyers are also in violation. If verified by law enforcement, both parties will bear legal responsibility, facing detention of 5 to 10 days and fines. Hit-and-run cases: If the points deducted by the buyer are due to a hit-and-run incident, and the seller cannot provide evidence of their absence during the incident, law enforcement may identify the seller as the responsible party. The seller would then have to bear the related responsibilities of the case, including revocation of the driving license and a lifetime ban from obtaining a driving license. If criminal liability is involved, it will also be pursued. Drunk driving: More severe point deductions occur if the buyer was driving under the influence of alcohol, caused a traffic accident, and resulted in fatalities. In such cases, the responsible party would be charged with the crime of traffic accident offense. The seller is highly likely to assume the related responsibilities of the accident on behalf of the buyer (including criminal imprisonment and civil compensation, etc.).

Where to Pay the Purchase Tax for a New Car?

Automobile purchase tax is paid at the relevant window of the State Taxation Bureau in the local administrative hall. The purchase tax must be paid within 60 days from the date of purchase. When going to pay, you need to bring the original and a copy of your ID card, the car purchase invoice, and the original and a copy of the vehicle qualification certificate. Below is relevant information: How to calculate the purchase tax: The taxable amount equals the taxable price multiplied by the tax rate, where the taxable price is the total price and additional fees paid to the dealer. For example, the purchase tax for a car priced at 100,000 yuan would be 100,000 divided by 1.17 multiplied by 10%, resulting in 8,547 yuan. This 8,547 yuan is the purchase tax required for a 100,000 yuan car. Where to pay the automobile purchase tax: In 2015, the state implemented a policy exempting eligible new energy vehicles from purchase tax. The original deadline was December 31, 2017, but the policy was extended for three years. The current policy deadline is December 31, 2020, so purchasing a new energy vehicle now can save you the cost of the purchase tax.

Can You Buy a Flood-Damaged Car When Purchasing a New Vehicle?

It is possible. A flood-damaged car refers to a vehicle that has been submerged in water. The extent of water damage can vary depending on the level of submersion, generally categorized into three levels: first, when water reaches the tires; second, when water reaches the hood; and third, when water reaches the roof—from least to most severe. Typically, the first level is not a major concern, while the second and third levels are more serious. Below is relevant information: Considerations: Purchasing a flood-damaged vehicle requires caution. If the goal is to reduce the cost of buying a car, opting for a flood-damaged vehicle may be acceptable, but it comes with risks to the vehicle's lifespan and driving safety. For those considering buying a flood-damaged car, the first-level flood-damaged vehicles may be acceptable. However, second- and third-level flood-damaged cars are not recommended, even if the price is low, as they compromise driving safety—essentially risking one's life. Hazards of Flood-Damaged Cars: Flood-damaged vehicles pose significant risks, with numerous potential component failures, such as brake failure, frequent stalling, or engine smoke. These issues can severely impact driving safety.

How to reset the tire pressure monitoring on the VV5?

VV5 tire pressure monitoring reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep" sound, then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the fault light on the dashboard will turn off, completing the tire pressure reset. Precautions for inflating tires: Always use a pressure gauge to check the pressure to avoid over-inflation, which can cause the tire to burst. After stopping the vehicle, wait for the tires to cool down before inflating, as driving increases tire temperature, affecting the pressure. Check the valve stem. If the valve stem and core are not properly aligned, have uneven surfaces, or other defects, it may complicate inflation and pressure measurement. Pay attention to cleanliness during inflation. The air being pumped in should not contain moisture or oil, as it can deteriorate and damage the inner tube rubber. Do not exceed the standard pressure excessively and then release air, nor should you over-inflate due to prolonged inability to inflate while traveling. Exceeding the standard pressure too much can overstretch the cords, reducing their strength and affecting the tire's lifespan.
