According to the vehicle's maintenance manual, the car's air filter should generally be replaced every 10,000 to 20,000 kilometers or during every other maintenance service. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the buildup of throttle sludge. The location of the air filter varies depending on the intake system design and engine structure. It is typically located within the air cleaner housing attached to the engine's intake pipe. There are two types of automotive air filters: dry and wet. Dry filters are made of paper or organic materials, while wet filters are constructed with metal mesh. The function of the air filter is to remove particulate impurities from the air, ensuring sufficient clean air enters the cylinders and preventing airborne dust from being drawn into the engine, which accelerates wear on piston assemblies and cylinders. Mercedes C-Class Air Filter Replacement Tutorial Location: Right side of the engine bay, connected to a prominent large intake pipe. The tools required for removing the air filter are common and should be prepared in advance (Phillips screwdriver, flathead screwdriver, hex socket, etc.). Locate the air filter housing and use the appropriate tools to loosen the fasteners. Lift the air filter housing cover to access the old filter. To determine if the filter needs replacement, it is convenient to remove it from the housing. If the filter is slightly dirty, it can be cleaned with compressed air and reused. However, if the filter is damaged or excessively dirty, it should be replaced immediately. Note: Some models may require disconnecting rubber couplings when removing the air filter. Air Filter: A filtration device also known as an air filter cartridge, air cleaner, or air element. It is primarily used in engineering vehicles, automobiles, agricultural machinery, laboratories, sterile operating rooms, and various precision workspaces. The engine draws in large amounts of air during operation. Without filtration, airborne dust entering the cylinders accelerates wear on piston assemblies and cylinders. Larger particles entering between pistons and cylinders can cause severe cylinder scoring, particularly in dry and sandy environments. The air cleaner is installed before the carburetor or intake manifold to filter out dust and sand, ensuring sufficient clean air enters the cylinders. Dirty Air Filter: Using a heavily soiled air filter while driving can restrict engine airflow, leading to incomplete fuel combustion. This results in unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The automotive air filter is a device that removes particulate impurities from the air, consisting of one or more filtration components. Its primary function is to filter harmful impurities from the air before it enters the cylinders, reducing premature wear on cylinders, pistons, piston rings, valves, and valve seats. Thus, air must pass through the fine filtration of the air cleaner before entering the cylinders. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if minimal dust and light clogging are observed, it can be cleaned with high-pressure air from the inside out and reused. Severely dirty air filters should be replaced promptly.

How to Replace the Battery in a Volkswagen Car Key?

Open the folding part of the key, and use a flat-head screwdriver to slowly pry into the middle of the gap. When a larger gap is created, hold the key ring below and pull hard to separate the key into upper and lower parts. Forcefully pry open the side, and this part of the key will split into front and back pieces, revealing the battery section and the circuit board section. Remove the old battery and replace it with a new one.

How to Repair Scratched Car Paint?

Wash the car thoroughly, and if not necessary, clean the scratched area specifically, then prepare the tools. After maintaining a certain distance from the scratch, start spraying the paint. The sprayed paint can make the car's paint smoother, which is difficult to achieve by simply using the attached brush. After applying the paint, wait a few minutes for it to dry. Then, prepare the blending clear coat and assemble it onto the mini spray can. Maintain a certain distance and spray the blending clear coat back and forth over the area where the paint was applied, trying to avoid spraying on areas without paint. Wait a moment, and the paint repair is complete.

How to Identify High-Pressure Common Rail Faults?

Check whether the rail pressure sensor signal voltage terminal 214 (A26) is open circuit. Measure the voltage at pin 2 of the connector with a multimeter; the normal range is 4.9-5.1V. Check the rail pressure sensor signal voltage terminal 214 for short circuit to ground. Turn off the ignition switch and unplug ECU connector 2. Turn on the ignition switch and measure the resistance between ECU harness terminals 213 (A07) and 214 (A26) with a multimeter; the normal reading should be infinite.
