If only the steel plate is scratched, simply applying some paint will suffice; if the pipes are damaged, a thorough inspection and repair are necessary, possibly requiring the replacement of oil pipes. Below are methods to prevent chassis scratches and damage: 1. Apply chassis armor: Automotive chassis armor can be sprayed on exposed areas such as the vehicle chassis, wheel hubs, fuel tank, lower body panels, and trunk. It quickly dries to form a tough, elastic protective layer that not only prevents impacts from flying stones and gravel but also protects against moisture, acid rain, and salt erosion on the chassis metal, preventing rust and corrosion, thereby ensuring driving safety. 2. Install an engine guard: The engine guard is a custom-designed protective device for various car models, primarily aimed at preventing mud from covering the engine and secondly to protect the engine from damage caused by uneven road surfaces during driving.

As a technician with years of experience in car repair, I've seen many cases where BMW chassis get scraped. The BMW 5 Series has a relatively low chassis, making it prone to scraping, especially on bumpy roads or when going over speed bumps. If it's just a minor scratch, it's usually not a big deal—it might only damage the surface paint and won't immediately affect safety. However, if the scrape is deep, it could harm components like the fuel tank, exhaust pipe, or suspension, leading to oil leaks, rust, or unstable handling. BMW's chassis design is highly precise, and repair costs are steep—minor repairs can cost a few hundred yuan, while major repairs can run into thousands. If you notice a scrape, it's best to lift the car and inspect it as soon as possible. Applying anti-rust paint or installing an underbody guard may be necessary. When driving, control your speed and avoid rough roads. During regular maintenance, have a professional mechanic check the chassis to prevent bigger issues. A small oversight can lead to major trouble, so don't take it lightly.

How to Distinguish Between Stock Cars and New Cars

Methods to distinguish between stock cars and new cars include checking the vehicle production nameplate, examining the window production date, and inspecting the vehicle identification number (VIN). Below are the detailed explanations: 1. Check the vehicle production nameplate: Every car is affixed with a nameplate before leaving the factory. This nameplate not only contains information such as the vehicle model but also the manufacturing date of the vehicle. Therefore, by checking this area, you can directly and easily determine the production time of the vehicle, making it the simplest way to verify the manufacturing date. This ensures you don't end up purchasing a stock car that has been sitting for too long. 2. Examine the window production date: On the car's front windshield, there is usually a production date for the glass. Based on this date, you can estimate the timeframe in which the glass was produced and determine whether the glass has been replaced. After all, the production dates of the vehicle and the glass should not be too far apart. 3. Inspect the vehicle identification number (VIN): The VIN is a 17-digit code that can be used to determine the production date of the car. The 17 digits are divided into three parts. You can check the 10th digit, which represents the production date of the vehicle. By verifying the 10th digit, you can confirm the production time.

What causes the rear air vents in the Boyue Pro to have no airflow?

The reasons for no airflow from the rear air vents in the Boyue Pro include blower malfunction, clogged cabin air filter, and control system failure. Below are detailed explanations for each of these causes: Blower malfunction: The blower is the core component determining whether the car's air conditioning system produces airflow. If it is damaged, the car's air conditioning will inevitably fail to blow air. Blower malfunctions are typically caused by overheated internal coils or capacitor damage. You can check for blower issues by turning the car's air conditioning speed and airflow to maximum and listening for the blower's sound. If a malfunction is detected, it is necessary to visit a 4S shop or repair facility for servicing. Clogged cabin air filter: A clogged cabin air filter is one of the most common causes of airflow blockage in the system. Outside air passes through the cabin air filter before entering the car's interior, trapping various airborne particles, which can lead to clogging. You can remove the cabin air filter to inspect its cleanliness and replace it if it is excessively dirty. Control system failure: If neither of the above causes applies, the issue may lie with the car's air conditioning control system. Possible culprits include the air blend door, control switches, or the air conditioning computer. In such cases, it is advisable to contact a professional for diagnosis and repair.

What is the brightness of Audi headlights?

Brightness is generally expressed in lumens. A 75W xenon lamp with 5000LM might achieve extreme brightness, but Philips does not produce such lamps. They only offer 35W xenon lamps with 3200LM. If using xenon lamps, a low beam with 4500K (standard is 4250-4300K) is sufficient for all-weather use. The difference between headlights and low beams: The difference between headlights and low beams is that low beams can be part of the headlights, but headlights are not necessarily low beams, as headlights include both low beams and high beams. High beams focus light in a parallel, concentrated beam with high brightness, allowing illumination of distant and higher objects. In contrast, low beams emit light in a diffused pattern, covering a wider area but with a shorter range. Driving in dimly lit areas: When driving in dimly lit areas or places without streetlights, it is mandatory to turn on the low beams. In conditions of heavy fog, snow, or rain that obstruct visibility, low beams should also be used during the day. High beams should only be used on roads without lighting and when there are no oncoming vehicles, as they can severely impair the vision of other drivers and potentially cause traffic accidents.

What kind of oil should be added to the transmission?

Transmissions require specialized transmission oil, also known as gear oil. The differences between gear oil and engine oil are as follows: 1. Different environments: Gear oil, or transmission oil, is specifically designed for use in transmissions. It is a type of transmission lubricant used for lubricating various gears in transmissions, reducers, and differentials, operating in relatively low-temperature environments. Engine oil, or engine lubricant, is used inside the engine to lubricate internal components, enduring long-term high-temperature and high-pressure conditions, requiring higher oxidation resistance and stronger shear resistance. 2. Different functions: Both have lubricating properties. Gear oil prevents wear and sintering on gear surfaces, extends service life, and improves power transmission efficiency. Engine oil serves to clean, lubricate, and cool the internal components of the engine.

What Type of Strobe Lights Are Not Illegal?

Strobe lights are all illegal. Privately installing strobe lights on vehicles, regardless of the type, is considered illegal. Strobe lights, due to their strong and rapidly flashing light, can interfere with the normal driving of other vehicles and pose a safety hazard. Strobe lights use electronic means (such as programming ICs with capacitors or microcontrollers) to make the light source flash slowly or quickly, serving as a warning. Previously, strobe lights were mainly used on police or special vehicles and were rarely used by civilians. These police strobe lights are regulated items and are widely used in entertainment venues, road traffic, advertising lighting, vehicles and ships, public security, and other fields. While installing such strobe lights is permitted under national traffic laws, they cannot be used in areas explicitly prohibited by national or city regulations. According to the "Road Traffic Safety Law of the People's Republic of China," installing strobe lights on private vehicles is not only illegal, but traffic police departments are also required to forcibly remove them and impose corresponding fines for modifications. Article 15 of the "Road Traffic Safety Law of the People's Republic of China" stipulates that police cars, fire trucks, ambulances, and engineering rescue vehicles must be painted with designated markings and equipped with alarms and lights as required. Other motor vehicles are prohibited from painting, installing, or using the specific markings and lights designated for these vehicles.
