What Causes Tire Vibration at Idle?

Minor tire vibration at idle is normal. Below is additional information: Introduction to Idle Vibration: Idle vibration occurs when the engine is running but the oil supply doesn't keep up promptly, resulting in poor mechanical operating conditions for the engine or issues like poor fuel injector atomization and improper idle adjustment, which cause engine vibration. If noticeable body vibration occurs when starting the vehicle or when the vehicle is stationary with the engine running, it is usually due to severe engine carbon buildup or a dirty throttle body. When there's excessive carbon buildup inside the engine, the gasoline sprayed by the cold-start injector is largely absorbed by the carbon deposits, leading to an overly lean air-fuel mixture during cold starts and making it difficult to start. In this situation, the engine will only start easily once the carbon deposits are saturated with gasoline. After starting, the gasoline adsorbed on the carbon deposits is drawn into the combustion chamber by the engine's vacuum, enriching the air-fuel mixture again. This fluctuation between lean and rich mixtures causes idle vibration after a cold start. Solutions for Idle Vibration: If the car body vibrates when stationary in N gear, with noticeable seat and steering wheel vibrations, and the vibration is obvious while driving, but the engine power is normal and no engine fault indicator is lit on the dashboard, this is mostly caused by aging, cracking, or oil leakage in the engine mounts. You can check the engine mounts for faults and replace them if necessary.

How to Determine if the Compressor is Damaged?

Compressor 3 terminal posts between the resistance value check to the difference is larger, the compressor may be damaged. Here is more information about automotive compressors: 1. Introduction: The automotive air conditioning compressor is the heart of the car's air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Compressors are divided into fixed displacement and variable displacement types. According to different working principles, air conditioning compressors can be classified into fixed displacement compressors and variable displacement compressors. 2. Classification: Based on different working methods, compressors can generally be divided into reciprocating and rotary types. Common reciprocating compressors include crankshaft connecting rod type and axial piston type, while common rotary compressors include rotary vane type and scroll type.

Where is the steering wheel heating switch on the BMW 3 Series?

The steering wheel heating switch on the BMW 3 Series is located at the lower left side of the steering wheel. Pressing this switch will activate the heating function for the steering wheel. The BMW 3 Series is a sporty midsize sedan under the BMW brand, equipped with three types of engines: a low-power version 2.0-liter turbocharged engine, a mid-power version 2.0-liter turbocharged engine, and a high-power version 2.0-liter turbocharged engine. The BMW 3 Series represents the new generation of sedan products from BMW Group, with a body weight of 1,465 kilograms and powered by an inline 4-cylinder gasoline engine. The vehicle's dimensions are 4.734 meters in length, 1.811 meters in width, and 1.455 meters in height, with a wheelbase of 2.92 meters.

What is the difference in wheel sizes?

The differences in wheel sizes are as follows: 1. Large-sized wheels are generally paired with low-profile tires, which gives the entire wheel a higher lateral stiffness. This means that under conditions with large lateral forces, such as high-speed cornering, the wheel deforms less compared to standard wheels, thereby improving handling sensitivity. 2. Large wheels reduce the amount of tilt when the vehicle turns, enhancing handling. Wider tires with a smaller aspect ratio provide better stability and greater grip during high-speed driving. 3. Smaller wheels offer better comfort. For the same car model, smaller wheels result in taller tire sidewalls, meaning the tires are thicker. While this may not look as aesthetically pleasing, it significantly reduces vehicle vibrations and tire noise. 4. Small-sized wheels and tires are much less likely to suffer wear and tear compared to large wheels. Additionally, the cost of replacement is not as expensive. Moreover, smaller wheels contribute to lower fuel consumption.

How often should the transmission fluid be changed in a BMW 3 Series?

BMW 3 Series requires transmission fluid change every 80,000 kilometers. Prolonged failure to change the transmission fluid can lead to gear shift jerking and may damage the transmission's shift control mechanism. The BMW 3 Series is a sporty B-segment sedan under the BMW brand, equipped with ZF's 8AT transmission. This model has been localized for production in China, with the domestic version featuring three engine options: a low-power 2.0-liter turbocharged engine, a medium-power 2.0-liter turbocharged engine, and a high-power 2.0-liter turbocharged engine. The low-power 2.0-liter turbocharged engine delivers 156 horsepower and a maximum torque of 250 Nm; the medium-power version produces 184 horsepower and 300 Nm of maximum torque; while the high-power variant generates 258 horsepower and 400 Nm of maximum torque.

What Does the Urea Warning Light Look Like?

Indicator light is a fuel tank symbol with the text AdBlue on it, which typically illuminates when the urea fluid level is too low. Below is more information about the urea warning light: 1. Function: Automotive urea is a diesel exhaust fluid that uses SCR (Selective Catalytic Reduction) technology to reduce exhaust emissions. 2. Solutions: When the urea warning light comes on, there are three ways to address it. The first scenario is if the vehicle exhibits symptoms like lack of acceleration or white smoke from the exhaust pipe, in which case professional equipment should be used to clean the urea crystallization inside the exhaust pipe. The second scenario is when the vehicle's fault code indicates low urea pressure, requiring urea replenishment. The third scenario is caused by engine torque limitation, where the RPM cannot exceed 1800 for 8 minutes, necessitating the replacement of the urea pump and sensor.
