Why does the engine malfunction light come on and the vehicle shake?

When the engine malfunction light comes on and the vehicle shakes, the reason is poor combustion of the air-fuel mixture. Poor combustion can lead to carbon buildup in the engine, which is the primary cause of vehicle shaking. Additionally, when the oxygen sensor detects poor combustion and reports it to the ECU, the malfunction light is triggered as a warning. This is why the engine malfunction light and vehicle shaking often occur simultaneously. Several issues can cause poor combustion of the air-fuel mixture, including faulty spark plugs, malfunctioning ignition coils, fuel pump failure, or clogged fuel lines. If the engine malfunction light comes on, follow these steps: First, check whether the engine is running normally. Look for symptoms such as shaking, black smoke, or difficulty starting. If any of these issues are present, avoid restarting the engine. Note: If the red warning light is on, do not restart the engine under any circumstances. If the engine is running normally and the vehicle can be driven, visit a service center as soon as possible to diagnose the issue. A service center can easily read the trouble codes using a portable diagnostic tool, allowing for targeted repairs based on the fault information. If the engine is running normally, the owner can also try gently reconnecting wiring harness connectors, as a loose connection may be the cause. Alternatively, repeatedly turning the key to the ON position may help reset the system.

Is slight bubbling normal after tire repair?

It is not normal to have slight bubbling after tire repair. The following are the possible causes of bubbling: Cause 1: It may be due to the fact that the tire was not repaired in time after being punctured by a nail or the puncture hole was relatively large, allowing air to enter the inside of the tire. The air then escapes from the internal puncture hole, forming slight bubbles. After the repair, observe whether the bubbles bulge or not. If they do not bulge, it is mostly caused by air leakage, and this phenomenon may last for two days without affecting the tire pressure. Cause 2: Incomplete tire repair leads to air leakage, which can cause the gas inside the tire to leak out quickly. In this case, the bubbling area needs to be rechecked and repaired. During the tire repair process, the bubbles that appear are called "pinholes," which are small holes caused by high-pressure gas. When pinholes appear on the tire, it also indicates that the car tire is leaking air.

How to Deal with Foggy Windshield on BMW X1?

Press the defogging button, turn on the air conditioning cooling (A/C) switch, set the temperature to the lowest, and turn on the external circulation to defog. Both cold and warm air can be used to defog the car glass, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving the purpose of defogging. The method of using warm air to defog is the same as using cold air, but it should be noted that warm air should not be used for defogging on rainy days, as it will initially worsen the fog. When the car glass fogs up, the external circulation should be turned on. The reason for car glass fogging: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface with the lower temperature will have a lower saturated vapor pressure than the surrounding environment, causing water vapor to gather on the glass surface and form tiny water droplets, resulting in fog. Methods to defog car glass: Air Conditioning Cooling: Use the air conditioning's dehumidification function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car, if the air conditioning is not turned on in time, the high humidity of the exhaled air can quickly cause the windshield to fog up. At this time, you can turn on the air conditioning to blow cold air onto the windshield, using the air conditioning's dehumidification function to quickly remove the fog. However, if the humidity is too high and the air conditioning is not effective, you can slightly open the window to quickly reduce the humidity inside the cabin. Of course, combining this with the air conditioning will yield faster results. Air Conditioning Warm Air: Use the method of reducing the temperature difference to remove fog. In winter, blowing warm air onto the glass quickly raises the temperature of the windshield, reducing the temperature difference between the inside and outside surfaces of the glass, thereby preventing excessive fogging. However, it should be noted that the rear and side windows heat up more slowly, so it takes longer to completely remove the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification. The temperature control should not be set to the coldest position, as this can cause the outer surface of the windshield to fog up over time. Spraying Anti-Fog Agents for Prevention: Spray a small amount of defogging agent on the car glass and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed, which effectively prevents water vapor from condensing on the glass and forming fog. This is especially useful in cold winters. Alternatives to defogging agents include dishwashing liquid, soapy water, glycerin, alcohol, or salt water. After drying, wipe off any excess with a chamois or soft dry cloth to ensure the glass remains fog-free for several days. Opening Windows for Airflow: If the fog inside the car is not heavy, you can open the windows on both sides to create airflow between the inside and outside of the car, reducing the temperature difference and gradually dissipating the fog. The principle of this method is the same as using cold air from the air conditioning. The downside of opening windows is obvious: it cannot be used in rainy or snowy weather, on highways, or when the fog is heavy. Rear Windshield Heating: Most cars have a rear windshield heating function, although the button positions may vary, the function is the same. Turn on the windshield heating switch, and the fog on the rear windshield will disappear in about a minute.
