To start a BMW 3 Series, first press the brake pedal and then the start button. After the ACC light turns on, press the start button again; the one-touch start button will turn green, and the vehicle will begin self-inspection. Once the self-inspection is complete, press the brake pedal and the start button again to start the vehicle. The following precautions should be noted when starting a BMW 3 Series: 1. Ensure the gear is in P (Park): If the gear is in D (Drive) or R (Reverse), directly starting the engine is very dangerous as the vehicle may lurch forward or backward. Forgetting to engage the handbrake in such a situation can lead to severe consequences. 2. Press the brake pedal before starting: If you press the one-touch start button without pressing the brake, only the vehicle's electrical circuits will be activated.

When I first got my BMW 3 Series, I didn’t know how to start it, but I figured it out later. Sit in the car with the key, keep your foot on the brake pedal without releasing it, and directly press the round button with the engine logo on the center console—the engine will roar to life. If you press the button without stepping on the brake, it will only power on without starting the engine. After starting, don’t rush to drive; wait for the dashboard needle to drop below 1,000 RPM before shifting gears. By the way, just keep the key in your pocket—no need to take it out. If the key runs out of battery, press it near the start button for an emergency start. Before turning off the engine, remember to shift to P (Park) and pull the handbrake, or the car will alert you about improper gear shifting.

Veteran drivers have a particular way of starting a BMW 3 Series. After sitting down, don't press the accelerator immediately. First, place your right foot on the brake pedal and press it all the way down, then locate the START button on the right side of the steering wheel and press it. Remember, you must press the brake pedal firmly—this is a safety feature. At the moment of ignition, the RPM will surge to 1,500, then drop to around 800 after about 30 seconds. Only then should you shift to D and drive off. A loud engine sound during a cold start is normal; it quiets down once the engine warms up. Once, I tried starting the car with the key in the trunk, and it wouldn't start—pretty smart system. If the car sits unused for a long time, keep an eye on the battery voltage; low charge can make starting difficult.

What is the most fuel-efficient engine RPM for a car?

Each car has its own economical RPM range. Here is some information about car RPM: 1. According to the law of energy conservation, the less fuel consumed, the less work is done, which also applies to the automotive industry. In the most fuel-efficient state, the power output is weaker, and of course, the speed won't be too fast. Therefore, to determine the most fuel-efficient RPM, we need to analyze it under low-speed conditions. 2. Currently, there are two mainstream types of engines in the domestic market. One is the small-displacement turbocharged engine, represented by the 1.5T, and the other is the larger-displacement naturally aspirated engine, represented by the 2.0L. These two types of engines have their own different economical RPM ranges. 3. Take a manual transmission car as an example. Of course, you need to be in the highest gear. While ensuring no jerking or shaking, try to reduce your speed. When the engine starts to shake, press the accelerator, and the RPM after pressing the accelerator is the economical RPM. For example, if a car is in fifth gear and the engine slightly shakes at 1400 RPM, indicating the need to downshift, but after pressing the accelerator, the RPM rises to 1600 RPM without shaking, then the economical RPM for this car is 1600 RPM. The same logic applies to most manual transmission cars. 4. To some extent, maintaining a high gear and low RPM without causing engine shaking or jerking is the most fuel-efficient. If the car has cruise control, after driving for a certain distance, the combined fuel consumption will be lower than the official fuel consumption.

What Causes Engine Oil Leakage in Cars?

The reasons for engine oil leakage in cars are: 1. Loose screws, damaged gaskets, or improper installation; 2. Leakage from front and rear crankshaft oil seals or improper installation of oil seals; 3. Improper installation of lubricating oil filters, pressure relief valves, sensors, etc.; 4. Cracks or holes in the oil pan; 5. Loose, broken, or poorly fitted oil pipes; 6. Leakage from the camshaft bearing rear oil seal cover. Solutions for engine oil leakage: 1. Replace the valve cover gasket; 2. Remove the oil pan, replace the oil pan sealing gasket, and reapply sealant; 3. Tighten or replace the drain screw. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine.

What are the symptoms of a damaged flywheel?

When a car's flywheel is damaged, it will cause abnormal noises from the engine during operation, accompanied by noticeable vibrations, and can also lead to an imbalance in the transmission shaft of the gearbox. The car flywheel is a disc-shaped component with a large moment of inertia, functioning like an energy storage device. Since the power strokes of each cylinder in the engine are not continuous, the engine speed fluctuates. When the engine speed increases, the flywheel's kinetic energy rises, storing energy. Conversely, when the engine speed decreases, the flywheel's kinetic energy reduces, releasing the stored energy. The flywheel helps minimize speed fluctuations during engine operation. The car flywheel is mounted at the rear end of the engine crankshaft. Through the clutch installed on the flywheel, it connects the engine to the vehicle's transmission system and engages with the starter motor to facilitate engine starting. Additionally, it serves as the integration point for the crankshaft position sensor and vehicle speed sensor. Methods to determine flywheel damage: Check if the starter ring gear on the flywheel is intact. If the ring gear shows severe wear at the tooth ends or broken teeth, the starter ring gear or the entire flywheel needs replacement. Inspect the flywheel surface for severe burns, impact marks, scratches, etc. If such damage is present, the flywheel must be replaced. Measure the wear depth of the grooves. If it exceeds 0.5mm, it indicates the flywheel is damaged and requires replacement.
