BMW X1 rear axle oil is generally replaced every 20,000-30,000 kilometers. For new vehicles, the rear axle oil should be changed during the 12,000-kilometer maintenance, and then inspected every 24,000 kilometers thereafter. Definition of rear axle oil: Rear axle oil generally refers to the rear axle differential lubricating oil of front-engine, rear-wheel-drive vehicles, also known as "gear oil". Function of rear axle oil: Automotive rear axle oil acts on gear transmission mechanisms such as the steering gear, transmission, and drive axle. It not only provides excellent lubrication and cooling effects but also has certain anti-corrosion and anti-rust properties. Additionally, it helps reduce gear surface impact and noise, making it essentially the "lifeblood" of gear transmission.

What is the recommended mileage for the first maintenance of a Mercedes-Benz C-Class?

The first maintenance for a Mercedes-Benz C-Class is recommended at 5,000 kilometers or within six months, whichever comes first. Similar to the BMW 3 Series and Audi A4L, the Mercedes-Benz C-Class does not offer free first maintenance services, meaning that the cost of the first maintenance after purchasing the vehicle must be covered by the owner. Details about the first maintenance are as follows: 1. The first maintenance refers to the initial service after the vehicle has been used. It is the first inspection after the initial break-in period, including the replacement of the lubricating oil and oil filter used during the break-in period, as well as an inspection of major components. 2. The first maintenance period is calculated from the date of vehicle delivery. According to relevant regulations, exceeding the first maintenance date is considered as voluntarily waiving the right to the first maintenance.

What Causes a Car to Stop Generating Electricity?

Here are the reasons why a generator may not generate electricity and their solutions: 1. The generator belt is broken or slipping, causing the issue. Tighten the adjustment device or replace the belt; 2. There is an open circuit in the generator output wire. Check the condition of the wire; 3. The rotor part is stuck. Manually test if it rotates smoothly. Below are methods to determine if the engine has a fault: 1. Use a multimeter in voltage mode. Set the multimeter knob to the 30V DC voltage range, connect the red probe to the generator's 'armature' terminal, and the black probe to the casing. Run the engine at medium speed or higher. The standard voltage for a 12V electrical system should be around 14V, and for a 24V electrical system, it should be around 28V. If the measured voltage is the same as the battery voltage, it indicates the generator is not generating electricity. 2. Use an external ammeter for testing. If there is no ammeter on the car dashboard, an external DC ammeter can be used for detection.

How to Clean Brake Dust on Car Wheels?

Brake dust needs to be removed with professional cleaning agents and brushes. If you want to remove brake dust, it is recommended to go to a professional car cleaning facility. It is normal to have brake dust on the rims, as some powder will fall off during the friction process between the brake pads and the brake discs. Here are the methods for selecting brake pads: 1. First, look at the friction coefficient. The friction coefficient determines the basic braking torque of the brake pads. If it is too high, it can cause the wheels to lock up during braking, loss of directional control, and burning of the pads. If it is too low, the braking distance will be too long. 2. Consider safety. Brake pads generate instantaneous high temperatures during braking, especially during high-speed driving or emergency braking. In high-temperature conditions, the friction coefficient of the friction material will decrease. 3. Check for comfort, including braking feel, noise, dust, smoke, and odor, which are direct reflections of friction performance. 4. Look at lifespan. Typically, brake pads can guarantee a service life of 30,000 kilometers.
