A bumper should be replaced when it is severely damaged. Functions of a bumper: During low-speed collisions, the bumper serves as a buffer to protect the front and rear body of the vehicle. It also provides some protection for pedestrians in case of an accident. To reduce passenger injuries during side collisions, door bumpers are often installed in cars to enhance the door's impact resistance. Repair methods: For crack repair, first remove the bumper and identify the damaged area. Use a plastic welding gun to heat and weld the backside of the crack; move along the crack while heating the plastic welding rod. Once welded, allow it to cool to complete the repair. For dent repair, remove the bumper and identify the deformed area; use a heat gun to warm the damaged section for reshaping.

Should the BMW headlight switch be placed at 0 or A position?

The BMW headlight switch has two different modes: 1. Place the vehicle switch at position O, which means the vehicle's light switch is in manual mode. You need to manually turn on the parking lights and low beams when using them. 2. Place the vehicle switch at position A, which means the vehicle is in automatic headlight mode. The vehicle's headlights will automatically turn on or off based on the ambient light level. More information about BMW headlights is as follows: 1. For daily use, you can place the headlight switch at position A: In this case, the vehicle's headlights are in automatic mode. When the front sensors detect insufficient external light, the vehicle will automatically turn on the parking lights and low beams, providing convenience to the driver without the need to manually operate the switch. 2. The function of BMW headlights: The driver does not need to operate the light switch; the vehicle will automatically turn on the low beams to illuminate the road for the driver. After exiting a tunnel, the headlights will automatically turn off based on sensor feedback.

Is the Jinglan Line a highway?

Jinglan Line is not a highway, but a national road, originally known as National Highway 104. It starts in Beijing and ends in Pingtan County, Fuzhou City, Fujian Province, with a total length of 2,420 kilometers. The Jinglan Line passes through eight provinces including Beijing, Tianjin, Hebei, Shandong, Jiangsu, Anhui, Zhejiang, and Fujian, traversing the Keqiao, Yuecheng, and Shangyu districts within Shaoxing. The name of the national highway is derived from the abbreviations of the starting and ending cities. Beijing is abbreviated as 'Jing,' and Pingtan is abbreviated as 'Lan,' hence National Highway 104 was renamed from its former names Jingfu Line and Beiping Line to Jinglan Line. However, the route remains unchanged, and the road length within Shaoxing is still 148.517 kilometers.

What does DTC mean in cars?

DTC in cars stands for Diagnostic Trouble Code. Here is a detailed introduction to automotive fault codes: 1. Meaning: Indicates the monitored faulty system - P for Powertrain; B for Body; C for Chassis; U for Network or Data Communication Transmission System fault codes. 2. First digit: Indicates whether it's a generic code (applicable to all vehicle manufacturers) or a manufacturer-specific code. For example: 0 refers to generic codes, while 1 refers to manufacturer-specific codes. General Motors in the United States, for instance, has specific numeric type codes to assist in diagnosing vehicle technical conditions. 3. Second digit: Specifies the type of affected faulty system, with numbers ranging from 1-7: 1 for Fuel and Air Metering System; 2 for Fuel and Air Metering System (specifically for injector circuit malfunctions); 3 for Ignition System or Misfire Monitoring System; 4 for Auxiliary Emission Control System; 5 for Vehicle Speed Control and Idle Control System; 6 for Computer Output Circuit System; 7 for Transmission.

What are the maintenance items for the BMW 320li?

BMW 320li maintenance items (replacement cycle in parentheses): 1. Engine oil and oil filter replacement (10,000 km): Improves oil quality, ensures smoother power delivery, and extends engine life; enhances the ability to filter impurities and debris. 2. Fuel filter (30,000 km): Removes impurities and moisture from fuel, allowing the engine to perform at its best. 3. Spark plugs (Platinum: 60,000 km; Iridium: 80,000 km): Prevents ignition difficulties and ensures the engine does not suffer from power loss. 4. Brake fluid (40,000 km): Absorbs moisture from the air, improves braking performance, and ensures driving safety. 5. Brake pads (should not be less than 3mm): Prolonged use can cause severe wear on brake pads, reducing braking effectiveness. Replacing brake pads ensures stable handling performance. 6. Air and cabin air filters (30,000 km): Improves the quality of intake air, allowing the air distribution system to function efficiently; enhances air quality by filtering dust and unpleasant odors. 7.

When to Use D+ and D- in Automatic Transmission?

Here is a detailed introduction on when to use D+ and D- in automatic transmission: 1. When going uphill or downhill: When frequently climbing long or steep slopes, if the automatic transmission's computer controls the gear shifting, there may be instances of gear dragging. This manifests as high gear with low speed, causing the engine to lack power and vibrate intensely, increasing the chance of incorrect air-fuel ratio. Incomplete combustion of the fuel mixture can easily produce a large amount of carbon deposits and increase fuel consumption. Using manual mode in such situations can effectively reduce these occurrences. When going downhill, avoid coasting in neutral and instead use engine braking to reduce the burden on the braking system. In this case, manual mode can be used to lower the gear by one or two levels to assist with braking, rather than relying on the computer to control the gear based on speed. 2. When overtaking or starting: Manual mode (D+ and D-) can be used when overtaking to manually downshift for greater power. This also applies when starting, especially in racing or at traffic lights.
