BMW X5 requires 7 liters of transmission fluid. Transmission fluid is an oil product used to keep the gear system clean, and its functions are: ensuring the normal operation of the transmission and extending the service life of the transmission device. Taking the 2021 BMW X5 as an example, its body dimensions are: 4930mm in length, 2004mm in width, and 1776mm in height, with a wheelbase of 2975mm and a fuel tank capacity of 83 liters. The 2021 BMW X5 is equipped with a 2.0T turbocharged engine, with a maximum power of 195kW and a maximum torque of 400Nm, paired with an 8-speed automatic transmission.

I've been helping people repair cars at an auto repair shop for over a decade and have encountered numerous transmission issues with BMW X5s. Transmission fluid levels really can't be taken lightly—there are significant differences between models: the older E53 with a six-speed transmission might need 6-7 liters; the common E70 or F15 series with eight-speed transmissions require 8-9 liters; and the newer G05 may need around 9 liters. The actual amount for a change depends on the specific condition of the car, including whether all the old fluid is fully drained. DIYers often overlook checking the dipstick, leading to underfilling (which causes high temperatures and rapid wear) or overfilling (which destabilizes pressure and damages components). I recommend using OEM-certified fluids like ZF Lifeguard and checking every 60,000 km. Trying to save money with DIY carries high risks—it's best to have a professional shop check the fluid level to avoid costly rework. Regular maintenance is critical for transmission longevity—negligence can lead to thousands in repair costs, so it's better to stay on top of scheduled servicing.

What causes the engine to make a whirring sound like wind?

Engine making a whirring sound like wind can be caused by the following reasons: Engine humming sound at idle: When the car is in normal idle state, the humming sound may be caused by the operation of the electronic fan used for radiator cooling. However, this sound is intermittent. If the humming sound persists, it may indicate a fault with the temperature sensor or temperature regulator. The owner should promptly inspect it to avoid abnormalities during driving that could lead to more serious vehicle malfunctions and cause financial losses. Humming sound during low speed or gear shifting: The humming sound during low speed or gear shifting is generally caused by excessive clearance between the piston and cylinder wall. This phenomenon can occur due to overly tight assembly during installation or abnormal wear. Another possible reason is engine knocking. In the early stages of engine knocking, a humming sound will be emitted, which may be caused by advanced ignition timing or excessive carbon deposits in the cylinder leading to knocking.

How to Use the Air Conditioning in the 2021 Leiling?

2021 Leiling air conditioning usage method: 1. Press the one-touch start button to start the vehicle; 2. Press the AC option to activate the air conditioning system; 3. Press the LO or GR indicators to adjust temperature; 4. Adjust the digitally displayed fan speed levels. The working principle of air conditioning: The compressor inhales low-temperature, low-pressure refrigerant gas from the evaporator outlet, compresses it into high-temperature, high-pressure gas discharged from the compressor. The high-temperature, high-pressure superheated refrigerant gas enters the condenser, where pressure and temperature reduction cause the refrigerant gas to condense into liquid, releasing substantial heat. Functions of air conditioning: 1. Cabin temperature regulation; 2. Humidity regulation; 3. Airflow regulation; 4. Air purification.

How to Distinguish the Clutch, Accelerator, and Brake?

From left to right, the pedals are the clutch, brake, and accelerator. It's actually quite simple. Whether in left-hand or right-hand drive countries, the positions of the clutch, brake, and accelerator do not change. The clutch is usually on the left, operated by the left foot, and is used along with the brake to control the gearbox. The pedal is the control device for the clutch assembly in a manual transmission car, serving as the 'human-machine' interaction component between the car and the driver. It is one of the 'five major operating parts' in car driving, whether during learning or normal driving, and is used frequently. For convenience, people often refer to it simply as the 'clutch.' Correct operation directly affects the car's starting, gear shifting, and reversing. The brake, located in the middle, is primarily used for decelerating or stopping the car and is generally operated by the right foot. The accelerator, on the far right, serves to speed up or slow down the car. For most people, the right foot is much more sensitive than the left, unless they are left-handed. In reality, left-handed individuals are rare. Therefore, the right foot provides more sensitive control over the accelerator and brake, ensuring smoother driving without jerking. Additionally, based on human emergency response capabilities, the right foot reacts faster than the left. Some might question whether the left foot needs to be more sensitive for the clutch. However, the time and force required to press the clutch are longer and greater than those for the right foot. Over time, even with light steps, it can become quite tiring. In this context, the right foot's flexibility is more developed than the left. Moreover, from the car's structural perspective, this arrangement is more reasonable for connecting the engine configuration and aligns better with the car's theoretical design.

What are the reasons for Mercedes-Benz air conditioning not cooling?

Mercedes-Benz air conditioning not cooling reasons are: 1. Lack of refrigerant; 2. Damaged air conditioning flap; 3. Loose drive belt of car air conditioning compressor; 4. Clogged air filter element and filter screen; 5. Water infiltration into the refrigeration system. The solutions for sudden car air conditioning not cooling are: 1. Add refrigerant; 2. Replace the air conditioning flap; 3. Clean the air filter element and filter screen. The functions of air conditioning are: 1. Filter the air entering the compartment; 2. Absorb moisture in the air; 3. Keep the air clean and prevent bacterial growth; 4. Prevent glass fogging; 5. Adjust the temperature of the compartment.

What Causes the Clicking Sound When Turning on the Car Air Conditioner?

If there is a sound when turning on the air conditioner, it may be due to the following reasons: Compressor Belt Noise: It could be caused by a damaged tensioner pulley of the compressor belt, or it might be a noise indicating a compressor malfunction. This sound is usually heard in the engine compartment. Blower Fan Noise: This is not only a noise when the air conditioner is on but also occurs when the external circulation is activated. The sound is typically heard inside the glove box and is usually a clicking noise. Internal/External Circulation Motor Failure: This could be due to a malfunction in the temperature control switch inside the dashboard or a failure of the internal/external circulation motor. The sound usually comes from within the center console panel. It is recommended to have it checked at a professional repair shop.
