BMW X3's original air filter is Mann-Filter. Function of the air filter: To filter out particulate impurities from the air. When the engine is running, it needs to draw in a large amount of external air. The air filter removes 'inhalable particles' from the air, which then enters (the intake manifold or) the cylinder to mix with gasoline for combustion. If the air filter fails to perform its intended filtering function, larger particles in the air will enter the engine and combust, leading to various 'faults,' such as the commonly mentioned carbon deposits and engine cylinder scoring. Location of the air filter: The air filter is located in the engine compartment. By unscrewing seven fixing screws and lifting the box, the air filter can be removed.

Why Does the Car Steering Wheel Shake?

Car steering wheel shaking is mainly caused by the following reasons: 1. Issues with the transmission system. In this case, you should first check whether the alignment angles of all tires are within standard parameters at a repair shop. 2. The belt is either too loose or too tight. 3. Excessive and harsh braking. High temperatures can cause the brake pads to deform after cooling. In this situation, it's best to replace the brake disc or, if replacement isn't necessary, have it resurfaced to restore it to a usable condition. 4. Severe wear of the tie rod end or minor deformations in the tire shape.

What is the Champion spark plug model number?

Champion spark plug model is T8126J. The function of the spark plug is: under the control of the engine computer, it introduces the high-voltage electricity generated by the ignition coil into the engine cylinder, generating a spark between the spark plug electrode gap to ignite the air-fuel mixture, thereby ensuring normal engine operation. Symptoms of a damaged spark plug include: 1. The insulator skirt, electrodes, and shell are covered with a layer of dark compound; 2. The engine feels sluggish during driving; 3. Backfiring or black smoke during exhaust; 4. Vehicle idle shaking and difficulty starting; 5. Blackening inside the exhaust pipe with raw fuel discharge; 6. Regular engine shaking.

What are the common issues with the L2B 1.5 engine?

Common issues with the L2B engine are as follows: 1. Intake manifold noise: When pressing the accelerator pedal hard for rapid acceleration, a continuous sound similar to a gas stove igniting can be heard from the engine compartment, which disappears upon releasing the accelerator. Many have found that this issue is caused by a damaged vacuum check valve in the intake manifold, and replacing the check valve can resolve the problem. 2. Aging: The intake manifold of the L2B engine is constantly exposed to high temperatures, causing the diaphragm of the vacuum valve to age quickly. Once aged, the suction force causes the flap to hit the intake manifold, resulting in noise.
