What are the reasons for the shaking during cold start of BMW 5 Series?

The reasons for the shaking during cold start of BMW 5 Series are: 1. Excessive carbon deposits inside the engine, leading to an overly lean air-fuel mixture during cold start, causing shaking; 2. Mechanical failures such as ignition coils, spark plugs, or fuel injectors; 3. Low oil pressure or cylinder pressure, resulting in insufficient power; 4. Poor fuel quality; 5. Damaged or excessively dirty idle control valve; 6. Intake manifold leakage; 7. Damaged engine mounts or rubber pads; 8. Oxidized or low-grade engine oil. Taking the 2021 BMW 525li as an example, it is a mid-to-large-sized 4-door 5-seater sedan with a body size of 5106mm in length, 1868mm in width, and 1500mm in height, with a wheelbase of 3105mm. This car is equipped with a 2.0T turbocharged engine and an 8-speed automatic transmission, delivering a maximum power of 135 kW and a maximum torque of 290 N·m.

Why is the Baojun 360 air conditioner not cooling?

The reasons why the Baojun 360 air conditioner is not cooling are as follows: 1. Refrigerant leakage: The refrigerant in the air conditioning system has completely leaked, resulting in no refrigerant, so the air conditioner does not cool. 2. Internal damage to the air conditioning pump: This prevents the cooling effect from starting. Generally, a damaged air conditioning pump will produce abnormal noises. 3. The condenser fins are too dirty: This causes the pressure and temperature in the air conditioning system to be too high, and the air conditioning pump stops working, so the air conditioner does not cool. Relevant information about car air conditioners is as follows: 1. Car air conditioner: It refers to the air conditioning device installed in the car, which can cool, heat, ventilate, and purify the air in the compartment, providing a comfortable riding environment for passengers, reducing the driver's fatigue, and improving driving safety. The air conditioning device has become one of the indicators to measure whether a car is fully functional. 2. Structure: It generally includes a cooling device, a heating device, and a ventilation device. This combined device makes full use of the limited space inside the car, with a simple structure and easy operation.

Is it okay to park in P gear without engaging the handbrake?

P gear parking still requires engaging the handbrake, otherwise it may cause damage to the transmission. When parking on a flat road, there is not much difference whether you engage the handbrake first or shift to P gear first. However, if parking on a slope, it is best to engage the handbrake first and then shift into P gear to reduce the burden on the car's transmission gears. Below is an introduction to the P gear: 1. P gear is the most common gear in automatic transmission models, usually located at the front position of the gearshift console, in front of the R gear. Its purpose is to lock the axle when the car is stationary on a slope. 2. The direct function of shifting into P gear is parking. When temporarily parking on a level road, shifting into P gear puts the car's transmission in neutral operation, completely interrupting the power transmission between the engine and the output shaft. The driver does not need to turn off the running engine during short waits. Additionally, the P gear has a wheel lock device, so even for long-term parking, the driver does not need to engage the handbrake.

Can Brake Pads Be Replaced by Yourself?

Brake pads can be replaced by yourself, but it requires some time and effort. When you notice that the brake pads have become thinner, the brakes produce unusual noises, the brake pedal feels lighter, or braking becomes less effective, it's time to replace the brake pads. When replacing brake pads, those on the same axle should be replaced together to ensure even braking force on both sides. Below are the steps for replacing brake pads yourself: 1. To replace the brake pads, you need to lift the car and remove the tire; 2. Remove the caliper bolts, open the brake caliper, and take out the old brake pads; 3. Push the brake piston back in, then install the new brake pads; 4. Reinstall the brake caliper, tighten the caliper bolts to the specified torque without over-tightening, then reinstall the tire; 5. After replacing the brake pads, press the brake pedal a few times to eliminate the gap between the brake pads and the brake disc, allowing the brake piston to reset. Then, check if the brake fluid pump is functioning properly. Once confirmed, the brake pad replacement is complete.

What is the speed for straight-line driving in Subject 3?

Generally, the speed should be within 30km/h on the road, and second gear is appropriate. Below are some tips for straight-line driving in Subject 3: 1. Three-point alignment: Find a suitable reference object as a visual guide, such as the lane divider line in the middle of the road, curbs, railings, trees, etc. Align any prominent part of the vehicle with the reference object, and make timely adjustments if deviation occurs. 2. Control the speed: Straight-line driving also has speed requirements, and you must reach the corresponding speed to pass. If there is a vehicle ahead, maintain a safe distance and slow down if the distance is too close; if the vehicle ahead speeds up and the distance becomes too large, actively follow up when the road conditions are good. 3. Keep the steering wheel steady: When holding the steering wheel, the left hand should mainly control it, while the right hand gently rests on it for easy gear shifting. Regardless of the speed, always make minor adjustments to the direction, with small movements, turning as much as needed and returning accordingly. Note that keeping the steering wheel still does not necessarily mean maintaining straight-line driving; instead, the vehicle should maintain an equal distance from the lane divider lines on both sides of the road.
