Passat Lingyu fuel pump relay is located under the steering wheel, and relay 167 is the one. Definition of relay: A relay is an automatic control device where the output undergoes a step change when the input (electrical, magnetic, acoustic, optical, thermal) reaches a certain value. Automotive relays are relays used in vehicles, characterized by high load switching capacity, impact resistance, and vibration resistance. Components: An automotive relay consists of a magnetic circuit system, contact system, and reset mechanism. The magnetic circuit system includes components such as the iron core, yoke, armature, and coil. The contact system comprises parts like the static reed, moving reed, and contact base. The reset mechanism is made up of reset reeds or tension springs.

I remember the fuel pump relay of the Passat Lingyu is usually hidden in the engine compartment's fuse box, specifically under that black plastic cover on the driver's side. Having driven this car for years, I once had a no-start issue caused by this very part. Pop the hood, and near the left front wheel there's a box—open it to find a row of small relays. The fuel pump one is typically labeled with a number like 109. Use a flashlight to carefully check the labels. If you can't locate it, the vehicle manual has diagrams for reference. On a related note, a faulty relay means the fuel pump won't operate, potentially causing hard starts or stalling. Regular checks for corroded connectors can save you a lot of trouble.

What are the differences between National Standard V and VI for vehicles?

The differences between National Standard V and VI for vehicles are as follows: 1. Different sulfur content: The sulfur content limit for National Standard VI gasoline is 50mg/kg, while for National Standard V gasoline, it is 10mg/kg. 2. Different implementation times: The National Standard VI was implemented in December 2014, whereas the National Standard V was implemented in December 2017. 3. Different durability mileage: Compared to VI, the durability mileage for V increased from 80,000 kilometers to 160,000 kilometers. 4. Different particulate matter particle numbers: Compared to National Standard VI, National Standard V imposes stricter limits on nitrogen oxides, with a 25% reduction for gasoline vehicles and a 28% reduction for diesel vehicles.

Why Are the Front and Rear Bumpers of Cars Made of Plastic?

Because the front and rear bumpers are the first components to come into contact with a pedestrian's body during a collision, plastic materials can minimize injury to pedestrians compared to metal materials. Here are the benefits of using plastic for car bumpers: 1. Lower cost: Plasticizing the front and rear bumpers undoubtedly reduces vehicle manufacturing costs, which is one of the most important factors considered by automakers. 2. Safety performance is not compromised: Plastic bumpers also provide a certain cushioning effect. When the bumper deforms, it absorbs most of the energy, thereby reducing harm to people or objects.

What is the working principle of a car air purifier?

The working principle of a car air purifier is as follows: 1. The micro fan (also known as a ventilator) inside the machine circulates the indoor air. 2. The car air purifier is typically composed of a high-voltage generating circuit negative ion generator, micro fan, air filter, and other systems. 3. The polluted air passes through the air filter inside the machine (undergoing dual filtration) to remove or adsorb various pollutants. It then passes through the negative ion generator installed at the air outlet (when operating, the high voltage in the negative ion generator produces direct current negative high voltage). 4. The air is continuously ionized by the negative ion air purifier, which generates a large number of negative ions. These are then blown out by the micro fan, forming a negative ion airflow to achieve the purpose of cleaning and purifying the air.

Can a Vehicle That Cannot Be Transferred Still Undergo Annual Inspection?

A vehicle that cannot be transferred can still undergo annual inspection, but it must be processed under the name of the original owner, and the original owner's ID card is required. For specific details, it is recommended to call the local vehicle management office for inquiries. If a vehicle is not transferred, not only is the annual inspection troublesome, but insurance is also very complicated. If the vehicle is involved in an accident, the insurance company will notify the owner or the user of the vehicle, but the compensation will definitely be paid to the previously designated insured account or beneficiary account. Below is an introduction to the new regulations regarding vehicle annual inspections: 1. Non-commercial passenger cars (including non-commercial small and micro passenger vehicles) are subject to a 6-year exemption policy, meaning new vehicles within 6 years are exempt from on-site inspection. However, note that every 2 years, an application for an inspection mark must be submitted to the traffic management department; otherwise, it will be considered as failing the inspection. SUVs and MPVs with 7 seats or more do not qualify for the 6-year exemption policy. 2. Vehicles registered for more than 6 years are subject to an annual inspection policy; vehicles registered for more than 15 years are subject to a twice-a-year inspection policy.

What is the ECO mode in cars?

ECO refers to the car's economical driving mode function. ECO is an English abbreviation formed by the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator light on the dashboard illuminates, it indicates that the vehicle's economical mode has been activated. Eco mode is categorized into active and non-active types, with the difference being that the active type has a dedicated button, allowing the driver to choose whether to enable it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active Eco mode does not have a dedicated button. When the dashboard Eco indicator light turns on, it merely serves as a reminder function. The Eco mode automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most cars utilize the active Eco driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can enable the Eco mode. However, it is unnecessary to activate Eco mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of Eco mode but also affect the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the Eco mode to automatically deactivate. During idle parking or in N/P gear and manual mode, the Eco mode may also become ineffective. When a high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function in such scenarios.

How to Remove a Broken Key from the Lock?

Here are the methods to remove a broken key from the lock: 1. You can immediately call a professional locksmith for assistance. If a small part of the broken key is still sticking out, you can use pliers to grip it firmly and gently try to pull it out. 2. If you have small tools like tweezers on hand, preferably pointed-nose tweezers, insert them into the lock to extract the broken key. 3. You can also apply a small amount of strong glue to the broken surface of the key in your hand, quickly press it against the broken part inside the lock, and after 5 minutes, gently pull it out.
