Here are the reasons why half of the BMW X1's rear taillight is not working: 1. Reasons: The bulb may be burnt out, wiring may be overheating, the relay or combination switch may be damaged, the wiring may be open, the fuse may be blown, or there may be poor contact. 2. Inspection: When encountering a situation where the taillight is not working, pay attention to whether it's one light not working or both lights not working. If both lights are not working, it is highly likely to be a wiring issue or a problem with the relay switch. If only one light is not working while the other is functioning, it is most likely a bulb failure or poor contact. Car circuits are very complex; when problems arise, you can go to a repair shop and have a mechanic use a multimeter to test and identify which part is faulty. Some older cars may have aging wiring, which can lead to short circuits and cause issues.

The validity period after the third renewal of a driver's license is long-term. Documents required for renewing a driver's license: Bring your ID card, driver's license, four one-inch white-background color photos, and a medical certificate (physical examination form) issued by a county-level or above medical institution or a military medical institution at the regimental level or above to the local vehicle management office for processing.

Driver's license renewal cycle: The validity period of a motor vehicle driver's license is divided into six years, ten years, and long-term.

How many driving modes does the BMW 120i have?

The BMW 120i has 3 driving modes, which are: Economy Mode (ECO), Comfort Mode, and Sport Mode. Each mode offers drivers a different driving experience and enjoyment, but most owners frequently use the Economy Mode (ECO) because this driving mode can also help save fuel in traffic congestion. The specific introductions are as follows: 1. Economy Mode (ECO): Simply put, this mode helps the car save fuel. During driving, the vehicle's power output is restrained, so even if the driver presses the accelerator deeply, the car itself will not accelerate quickly but will instead accelerate slowly. 2. Sport Mode: The most intuitive feeling of this driving mode is the enhanced push-back sensation of the vehicle, but the magic of this mode is that it can clear carbon deposits in the engine. 3. Comfort Mode: This driving mode is more comfortable, and the overall stability of the vehicle body is further enhanced. Whether going over speed bumps, braking in emergencies, or accelerating, it is much more comfortable than normal driving, reducing a lot of jerky sensations.

Can unopened engine oil still be used after 10 years?

Unopened engine oil cannot be used after 10 years, as the shelf life of engine oil does not exceed 5 years. Shelf life of engine oil: Unopened engine oil generally has a shelf life of 5 years, while the remaining oil after opening has a shelf life of 1 year, and oil poured into the engine has a shelf life of 6 months. The main factor affecting the shelf life of engine oil is the storage conditions. The greater the temperature fluctuations and humidity in the storage environment, the faster the oil deteriorates. For every 1 degree Celsius increase in temperature, the lifespan of the oil is halved. Consequences of prolonged storage: If engine oil is stored for too long, the additives (such as antioxidants, detergents, and dispersants) will become ineffective, accelerating the oxidation process of the oil and causing it to lose its lubricating and protective properties. Instead, it may corrode the engine. If the oil has been stored for four or five years or even longer, check for abnormal odor, sediment, or unusual appearance (such as cloudiness or whitening) when opening the container. If any abnormal signs are present, it is best not to use the oil.
