The Audi A4 has two cabin air filters. One is located in the footwell area of the front passenger seat, and the other is in the engine compartment near the windshield. The cabin air filter is a crucial component of the vehicle's air conditioning system, which separates dust, pollen, and solid particles from the air, while also absorbing moisture, soot, ozone, odors, carbon oxides, SO2, and CO2. The Audi A4 is a B-segment vehicle manufactured by FAW-Volkswagen, with dimensions of 4763mm in length, 1826mm in width, and 1426mm in height, and a wheelbase of 2903mm. The door handle design of the Audi A4 emphasizes ergonomic efficiency and functional perfection, with sensitive pressure points for easy door opening.

I've been driving an Audi A4 for several years and have replaced the cabin air filter myself a few times. It's located inside the glove compartment in front of the passenger seat. First, open the glove box, and you'll find a plastic cover secured with clips. Remove it, and you'll see a rectangular housing where the filter is hidden. I usually replace it once a year, especially during high pollen seasons. Otherwise, the air blowing from the vents can develop a musty smell, which affects the driving experience. Buying filters online is very affordable, costing just a few dozen yuan, and installing it yourself saves on labor costs—both economical and convenient. Remember to handle the clips gently to avoid breaking them. Regularly changing the filter ensures clean air inside the car and prevents allergen buildup, which is crucial for long-term driving and passenger health.

From my experience in car maintenance, the cabin air filter for an Audi A4 is typically located under the glove compartment on the passenger side. You'll need to empty the glove box, then feel for the removable plastic panel at the back. Once removed, you'll see the filter housing. If you're not particularly handy, don't force it - be careful during removal and installation to avoid damaging components. I recommend replacing it every 1-2 years. If you frequently drive on dusty roads, the filter clogs faster, leading to reduced AC cooling efficiency and weaker airflow. When replacing, opt for a high-quality filter model that can trap more pollutants. Don't neglect this during regular maintenance - periodic checks ensure good cabin air quality and prevent bacterial growth.

What causes abnormal noises when the car is running?

Vehicle driving abnormal noise causes are as follows: 1. Exhaust pipe deformation: Generally, the exhaust pipe of front-engine models extends from the bottom of the car to the rear. When driving on rough roads or bumping the chassis, it is easy to cause the exhaust pipe to dent and deform. The deformed exhaust pipe increases exhaust resistance, resulting in a buzzing noise and resonance sensation. 2. Engine abnormality: Mainly caused by excessive wear of some parts or improper assembly and adjustment. Some abnormal noises can still be predicted, while engine abnormal noises may lead to accident damage. Therefore, when the engine makes abnormal noises, it should be repaired in time to prevent the fault from expanding.

What is TCS?

TCS stands for Traction Control System, which functions to control direction and improve traction when a vehicle skids, preventing loss of control. The Traction Control System determines whether the drive wheels are slipping by comparing the rotation speed of the drive wheels with that of the driven wheels. When the former exceeds the latter, it suppresses the rotation speed of the drive wheels as a form of anti-skid control. Vehicle traction control can be achieved by reducing throttle opening to decrease engine power or through brake control and wheel slip. Vehicles equipped with ASR (Acceleration Slip Regulation) utilize both methods, combining ABS (Anti-lock Braking System) and ASR.
