When I first drove my Volkswagen last year and saw the EPC light on, I was extremely nervous. It usually indicates an electronic stability system malfunction, most commonly caused by excessive carbon buildup in the throttle body or false signals from a faulty brake light switch. At the time, I felt the throttle response was sluggish, so I immediately went for a check-up. The issue was resolved after cleaning the throttle body. Ignoring it could lead to decreased engine performance or even sudden stalling while driving. The EPC light coming on is quite common in Volkswagen models, so I recommend getting into the habit of checking the throttle body and brake system every six months to prevent problems before they occur. Safe travel depends on attention to detail—don’t let small issues escalate into big troubles.

How to Replace the Air Filter in a Vezel?

The method for replacing the air filter in a Vezel is as follows: 1. Pull the engine hood release lever inside the cabin (located near the left foot) and move the internal hood latch to the right; 2. Lift the engine hood and secure it firmly with the support rod; 3. Unclip the metal fasteners on the air filter housing; 4. Open the air filter housing, remove the old filter, and wipe away dust and dirt inside the housing; 5. Install the new air filter, close the air filter housing, and fasten the clips securely. Taking the 2020 Vezel as an example, it is a compact SUV with body dimensions of 4328mm in length, 1772mm in width, and 1605mm in height, a wheelbase of 2610mm, and a curb weight of 1227kg. The 2020 Vezel is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 131PS, a maximum torque of 155Nm, and a maximum power output of 96kW, paired with a 6-speed manual transmission.

Is the AC in a car for cooling or heating?

ac switch is for cooling. When the vehicle needs cooling, pressing the AC button (the indicator light on the button will illuminate) activates the air conditioning in cooling mode. Adjust the temperature selection switch to the blue section, turn on the blower, and cold air will blow out. The AC is the compressor switch, and the compressor is the heart of the car's air conditioning cooling system, responsible for compressing and transporting refrigerant vapor. Below is relevant information: 1. Too much or too little refrigerant: This is the most common reason for air conditioning not cooling. Refrigerant leakage is the primary cause. When the air conditioning is not cooling, check the refrigerant level through the sight glass on the dryer. If the refrigerant is insufficient, the sight glass will continuously produce bubbles. If the refrigerant is too low, simply add more. Too much refrigerant can also prevent the air conditioning from cooling, as it affects the system's heat dissipation. Observe the sight glass on the dryer; if no bubbles appear during operation or after the compressor stops, it indicates excessive refrigerant. In this case, simply remove some. 2. Dirty condenser: Excessive accumulation of dust, lint, and other debris on the condenser and air filter can hinder the air conditioning system's heat dissipation, which in turn affects cooling performance.

How to Check if a Vehicle Has ETC?

To check whether a vehicle has ETC, the method is as follows: Currently, there is no online channel to check whether your new car has been registered for ETC by the previous owner. You need to bring relevant documents such as your ID card and vehicle license to an ETC service outlet and consult the staff. Below is the relevant information: 1. Cancellation method: The staff will contact the previous owner through the database and ask them to cancel the ETC at the bank where it was originally registered. If the previous owner cannot be contacted, the staff can only forcibly cancel the old ETC information in the background so that the new owner can apply for a new ETC service. 2. Cancellation time: If the previous owner is in the same province, the ETC cancellation can be completed in about a week. If the ETC was registered in another province, since ETC data is independent across provinces, the local institution will need to contact the relevant authorities in the other province, which takes more time. The processing time is about 45 days. If the new owner and the previous owner registered the ETC at the same bank, the bank also has the authority to cancel the previous owner's information.

Why is there engine oil in the Santa Fe's radiator?

Here are the reasons why there is engine oil in the Santa Fe's radiator: 1. After the cylinder head gasket is damaged, the oil passage and water passage are connected. Since the pressure of the engine oil is higher than that of the coolant, the engine oil enters the water passage and then flows into the radiator. Observe whether there are air bubbles escaping from the surface of the coolant in the radiator. 2. After stopping the engine, check whether the coolant automatically flows into the oil passage and then into the oil pan. Here are some relevant information: 1. When diagnosing the issue, it can be identified by observing the changes in the radiator and coolant. However, during observation, the water pump belt should generally be removed to stop the water pump, keeping the water in the radiator relatively stable. Avoid hastily replacing any single component. Only after confirming the faulty part should repairs be carried out. 2. Car radiator: Also known as a heat exchanger, it is a key component in the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, achieving temperature regulation. It is a part of the car engine.

What is the function of an automotive oil-water separator?

The primary function of an automotive oil-water separator is to separate water from fuel, ensuring more complete combustion in the engine cylinders and improving engine performance. An oil-water separator is a type of fuel filter, which includes membrane filtration oil-water separators, oleophilic material oil-water separators, non-powered oil-water separators, and demulsification oil-water separators. These separators are used in various industries such as automotive, food service, wastewater treatment, and petrochemical industries. Important notes regarding automotive fuel: 1. Using higher-grade fuel can help extend the engine's lifespan to some extent; 2. Different types of fuel should not be mixed.

What are the reasons for water leakage in the car's front passenger seat?

Water leakage in the car's front passenger seat can be caused by: Clogged sunroof drainage holes. During rainy days, if the sunroof drainage holes are blocked, rainwater cannot drain out and will seep into the car; Aging sunroof rubber seals. Plastic components harden and age over time, and once the sunroof rubber seals age, their sealing effectiveness decreases, leading to water leakage during rain; Clogged air conditioning drainage holes. Condensation water from the evaporator cannot drain out and will seep from the front passenger seat area; Poor door sealing. Incorrect installation or aging and deformation of door seals can reduce the car's sealing effectiveness, causing water to enter the car during rain; Clogged door drainage holes. Due to their low position, door drainage holes can easily get blocked by mud, preventing rainwater inside the door from draining and causing it to seep into the car. Methods to address front passenger seat water leakage: Use a dry towel or water scooping tool to remove accumulated water inside the car; Identify the leakage point and repair it accordingly. Effects of water leakage: Slight leakage around the sunroof can lead to mold growth; Door leakage can damage the door lock and affect the window lifting system; Trunk leakage can cause corrosion.
