The reasons why the car shakes when accelerating but stops when releasing the throttle are: 1. Excessive carbon deposits and low fuel pressure, leading to insufficient fuel supply and power, it is recommended to clean the fuel injectors and check the fuel pressure; 2. Poor ignition causing incomplete combustion, along with noticeably increased fuel consumption, it is advised to replace the spark plugs; 3. Insufficient cylinder pressure, which requires testing the cylinder pressure. Methods to reduce carbon deposits in the car include: 1. Regular car maintenance and oil changes; 2. Cleaning the car's air filter; 3. Regularly replacing the car's spark plugs; 4. Cleaning the car's throttle body; 5. Avoiding aggressive throttle inputs and minimizing sudden braking; 6. Regularly replacing the car's fuel filter.

Can You Still Drive with an Overheated Engine Coolant?

If the coolant temperature is too high, it is recommended not to drive the car for safety reasons. You should stop the vehicle (but do not turn off the engine immediately) and check the following: top up the coolant; inspect whether the thermostat is functioning properly; park in a shaded area; and continuously monitor the temperature gauge while driving, ensuring it does not exceed 95°C. To prevent engine overheating, pay attention to the following points: 1. Ensure the coolant is topped up; 2. Check if the thermostat is working correctly. If the thermostat fails to open the main valve as required, replace it with a new one promptly. If a replacement is not immediately available, temporarily remove the thermostat, but never leave a faulty thermostat at the outlet of the water jacket; 3. Park in a shaded area. If the engine temperature is too high, choose a shaded spot to park and cool down; 4. Continuously monitor the temperature gauge while driving, ensuring it does not exceed 95°C. In special circumstances, to enhance convective cooling, you can lift the engine hood to improve ventilation and heat dissipation.

Is the Mercedes-Benz C260 tire a run-flat tire?

Mercedes-Benz C260 tires are not run-flat tires. Additional information: Mercedes-Benz does not come equipped with run-flat tires; only BMW vehicles are originally equipped with run-flat tires. Generally, run-flat tires can continue to be driven for up to 80 kilometers after a puncture, which is sufficient to get the car to a shop for a tire change. However, run-flat tires have relatively poor comfort, so many car owners prefer regular tires. The C260 tire specifications are as follows: The Mercedes-Benz C260 tire model is 225/45-R17. The Mercedes-Benz C260 is equipped with a double overhead camshaft turbocharged direct-injection inline 4-cylinder engine, with a maximum power speed (rpm) of 5500, maximum torque (Nm) of 310, maximum torque speed (rpm) of 2000-4300, front tire specifications of 225/45R17, rear tire specifications of 225/45R17, and a non-full-size spare tire.

What are the hazards of tire pressure loss in BMW 3 Series?

Tire pressure loss in BMW 3 Series can increase tire body deformation, easily causing cracks on the tire sidewalls while generating flexing motion. This leads to excessive heat buildup, accelerating rubber aging, fatigue of the cord ply, and breakage of cord wires. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders. Causes of tire pressure loss: During vehicle usage, tire pressure loss may occur. If it's simply air leakage, inflation is sufficient. If the tire is damaged, timely repair or replacement is necessary. Tire pressure loss isn't terrifying - what matters is that owners understand its hazards and address it promptly to prevent accidents. Definition of tire pressure: Strictly speaking, it refers to the air pressure inside the tire. In automotive maintenance, while the engine is considered the heart of a car (its failure means the end of the vehicle's life), tire pressure is like the car's blood pressure. The level of tire pressure plays a crucial role in the vehicle's performance and power.

What are the steps for removing an automatic transmission?

Steps for removing an automatic transmission: 1. Remove the torque converter from the front of the automatic transmission, loosen the fastening bolts, detach the torque converter housing at the front of the automatic transmission, remove the output shaft flange and the rear housing of the automatic transmission, and detach the speed sensor's induction rotor from the output shaft; 2. Remove the oil pan by taking out the connecting bolts of the oil pan, then insert the blade of a specialized repair tool between the transmission and the oil pan to cut through the applied sealant; 3. Disconnect all wiring harness connectors attached to the valve body, remove each solenoid valve and the throttle cable connected to the throttle valve, carefully pry off the hydraulic oil pipes with a screwdriver, loosen the fixing bolts between the oil inlet filter screen and the valve body, and remove the oil inlet filter from the valve body; 4. Remove the connecting bolts between the valve body and the automatic transmission housing, take out the valve body assembly, extract the check valve, spring, and accumulator piston from the oil passage of the automatic transmission housing, and remove the manual control valve lever and the parking lock pawl. If necessary, the manual control valve operating shaft can also be removed.

Which Mercedes-Benz Series Have Ambient Lighting?

Currently, almost all models under the Mercedes-Benz brand come equipped with ambient lighting, from the top-tier S-Class down to the A-Class, making it a standard feature. Moreover, Mercedes-Benz offers up to 64 color options for its ambient lighting, which indeed adds a luxurious touch when illuminated at night. The Role of Ambient Lighting: Lighting serves as a tool to set the mood, and different colored lights can be used to create and express various atmospheres and moods. At the same time, well-designed ambient lighting can enhance one's mood and make driving more enjoyable. In Mercedes-Benz vehicles, the primary purpose of ambient lighting is decorative, with mood enhancement being a secondary benefit. Typically, ambient lighting comes in colors such as orange, blue, and green, and it also provides some degree of illumination. The lights are installed in locations like the door armrests, center console, and footwell. Installing Ambient Lighting: Since not all Mercedes-Benz models and versions come with factory-installed ambient lighting, owners who desire this feature for personal preference are advised to opt for the factory ambient lighting package. If the factory option is not available, the best alternative is to have ambient lighting professionally installed at a specialized facility. This remains the most reliable method outside of the factory option.

Why does the BMW 3 Series display a low coolant warning?

Low coolant means the coolant level is below the normal level, and the cooling system needs to be inspected. Thermostat failure: The thermostat is a component that automatically acts as a valve based on the engine's water temperature. It is usually installed at the outlet of the radiator and the inlet of the water pump. When the coolant temperature is low, the thermostat blocks the low-temperature coolant from the radiator, preventing it from entering the engine water jacket. This allows the water temperature in the jacket to rise quickly. When the water temperature reaches a certain level, the valve gradually opens, allowing the coolant from the radiator to circulate again. This coolant flows through the radiator, slowly increasing the water temperature while dissipating heat into the atmosphere, maintaining the engine's water temperature at an appropriate level—this is known as the major circulation. If the thermostat malfunctions and the valve cannot close, the coolant remains in the major circulation, potentially causing the engine's water temperature to drop too low. Alternatively, some vehicles may have their thermostats removed during summer to lower the temperature, which can also result in very low engine water temperatures. Radiator fan running continuously: Another issue is the radiator fan. For electric fans, circuit faults can cause the fan to run continuously. For viscous fans, a faulty viscous clutch can also lead to continuous fan operation. These issues can result in abnormally low water temperatures.
