Reasons for one side of the front fog light not working: 1. It could be due to a blown fuse, a short circuit in the bulb, or the bulb burning out. 2. Generally, if only one headlight is not working, it is mostly caused by a burnt-out bulb. 3. If both headlights are not working simultaneously, it could be due to a blown fuse, both bulbs burning out at the same time, or aging and breaking of the wiring or loose terminals, although the probability of these last two phenomena is very low. Solution: The vehicle's circuit fuse box is fixed under the hood in the engine compartment, near the fender. The exact location varies depending on the vehicle model. Locate the circuit fuse box, open the cover, and you will see various fuses and controllers of different amperages for electronic devices. The back of the cover has a corresponding diagram, which can help you locate the positions of the left and right headlight fuses. Use the included puller to remove the fuse and observe whether the contact points at both ends are melted. If there is a gap, it means the fuse is blown. If the node is normal, reinsert the fuse as it was and proceed to check both headlights.

What are the differences between the Prado and the Fortuner?

The differences between the Prado and the Fortuner are as follows: Different platforms: The Fortuner is based on the Hilux pickup platform, while the Prado is derived from the 4Runner SUV platform. Although both feature body-on-frame construction and share the same suspension setup—front double-wishbone independent suspension and rear four-link non-independent solid axle—there are slight differences in shock absorber tuning. The Fortuner tends to be firmer, whereas the Prado offers a more resilient and comfortable suspension, delivering a more refined and premium driving experience. Different four-wheel-drive systems: The second-generation Fortuner switched from full-time four-wheel drive to part-time four-wheel drive. In contrast, the Prado only adopted part-time four-wheel drive in its Chinese domestic version. Other regional versions, including the European, Japanese, Australian, and Middle Eastern models, continue to use full-time four-wheel drive. The full-time four-wheel-drive system, centered around a lockable Torsen center differential, represents the essence of Toyota's off-road technology. From this perspective, the Middle Eastern version of the Prado boasts a more advanced four-wheel-drive system compared to the Fortuner. Different body dimensions: Although both are seven-seat off-road vehicles, the Fortuner is slightly smaller in overall dimensions than the Prado, particularly in width, where it is four centimeters narrower. As a result, the Fortuner offers slightly less lateral seating space than the Prado. However, the longitudinal seating space is nearly identical between the two models.

What is the difference between BMW display cars and new cars?

BMW display cars and new cars have the following differences: BMW display cars and new cars appearance: New cars will have a layer of protective paper on the outside, while display cars in the showroom will have this protective paper removed, causing the paint on the car body to begin oxidizing with the air, leading to a gradual fading of the car's exterior color. Additionally, when display cars are viewed by customers, it is inevitable that some careless actions may scratch the car body, such as sharp objects like clothing accessories or keys. Therefore, when purchasing a car, it is essential to inspect the car carefully. For popular models, this might be less of an issue, but for cars that have been in inventory for a longer time, a more thorough inspection is necessary. This is because for older inventory cars, the one you see is likely the one you will buy, and getting a brand-new, untouched car is almost impossible. BMW display cars and new cars interior: Display cars are frequently sat in by people, which can cause slight deformation of the seats, especially leather seats, which may develop wrinkles from frequent use. Moreover, new cars typically have a pungent odor, but display cars are often treated to eliminate this odor for customer convenience. While the odor in new cars is not uncommon, it actually poses a safety hazard for car owners, as the smell is often due to formaldehyde. Formaldehyde is a common gaseous pollutant found not only in newly renovated homes but also in new cars. This is because new cars use many adhesives during assembly, and these adhesives contain large amounts of formaldehyde.

Does the new Audi A4 need a break-in period?

The new Audi A4 requires a break-in period, typically covering 1,000 to 2,500 kilometers. Reasons for the break-in period: When a new car leaves the factory, due to machining precision and assembly tolerances, a certain mileage is needed for proper break-in. The quality of the break-in significantly impacts the vehicle's lifespan, safety, and fuel efficiency. The standard break-in mileage is generally 1,000 to 2,500 kilometers, while imported vehicles often require longer periods, usually 1,500 to 3,000 kilometers. The break-in period consists of three stages: initial 100 kilometers, mid-term break-in of 200 kilometers, and oxide film formation over 3,000 kilometers. Break-in period precautions: Avoid emergency braking whenever possible, as it not only shocks the braking system during break-in but also increases impact loads on the chassis and engine. It's advisable not to perform emergency braking within the first 300 kilometers of driving. Avoid overloading the vehicle; running at full capacity during the break-in period may damage components. Therefore, within the first 1,000 kilometers, the load should generally not exceed 70% to 80% of the rated capacity. For highway driving, long-distance trips during the break-in period increase continuous engine operation time, potentially accelerating component wear. It's recommended to maintain speeds where the engine doesn't exceed 3,000 RPM at 120 km/h. If exceeding 3,000 RPM, consider reducing speed to keep RPMs under 3,000. During long trips, take breaks at service areas for about ten minutes. Avoid premature oil changes; the factory-installed oil is specifically formulated for break-in periods, featuring low viscosity, excellent heat dissipation, cleaning properties, and superior oxidation resistance. Some manufacturers even include special polishing additives to facilitate break-in. Follow the manufacturer's recommended oil change intervals without early replacement.

How Many Digits is the Engine Number?

Common engine numbers typically range between 7-8 digits. The sequencing and content of engine numbers may vary among different manufacturers. Generally, they include the engine model, production date, and a randomly assigned serial number given when the engine comes off the production line. Some may also include a place of origin code. Engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and engine attributes. It is used to represent information such as the manufacturer, specifications, performance, characteristics, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static brake power, among others. Engines installed in passenger cars or multi-purpose passenger vehicles are required to display the professional manufacturer, model, and production number of the engine. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and multiple engines can share the same model. On the other hand, the engine number is the production number of the engine, with each engine having a unique number that cannot be duplicated. Composition of a Vehicle Engine Number: Front Section: Includes product series code, generation symbol, and local or corporate code. Manufacturers may choose appropriate letters as needed, but these must be approved and filed with the industry standard regulatory body. Middle Section: Consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. Rear Section: Composed of symbols for structural features and usage characteristics. Tail Section: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols for representation. The rear and tail sections can be separated by a hyphen (-).
