What to Do When the Electronic Parking Brake Malfunctions?

Why does the vehicle shake when starting?

There are several main reasons: 1. Incorrect air-fuel ratio: The air-fuel ratio is not accurately adjusted, which occurs in both open-loop and closed-loop control. In a closed-loop control environment, the minimum operating temperature of the car's oxygen sensor is 370 degrees Celsius. However, when the vehicle is just started, the exhaust pipe temperature does not reach 370 degrees Celsius, and the oxygen sensor does not start working. At this time, the ECU makes a misjudgment, leading to errors in controlling the ignition timing through the actuator, thereby reducing power output and causing the vehicle to shake. 2. Carbon deposits on the engine valves and intake passages: Carbon deposits absorb fuel. Even if the remaining fuel burns completely, it cannot achieve the required power, making shaking inevitable. 3. Different working conditions of each cylinder: After long-term use, the spark plugs of a multi-cylinder engine may have different ignition control and timing gaps. However, the EDC cannot detect this error, leading to a deviation between theory and practice. Some cylinders may have lower efficiency, causing the vehicle to shake. 4. Failure of the coolant temperature sensor: The coolant temperature sensor is one of the important bases for the computer to judge the real-time working condition of the car engine. During a cold start, the engine temperature is low, but if the coolant temperature sensor misjudges and sends an excessively high signal to the computer, the computer will inject too much fuel. The fuel quantity is smaller than normal, and shaking is inevitable.

Reasons for Abnormal Noise in the Coolant Reservoir?

The vehicle's cooling system has malfunctioned. Below is an introduction to the vehicle's cooling system: 1. Introduction: The main function of the cooling system is to dissipate heat into the air to prevent engine overheating, but the cooling system also has other important roles. The engine in a car operates best at an appropriately high temperature. If the engine becomes too cold, it accelerates component wear, reducing engine efficiency and increasing pollutant emissions. Therefore, another key role of the cooling system is to quickly warm up the engine and maintain it at a constant temperature. 2. Common Issues: Engine Overheating: Air Bubbles: Air in the coolant can create many bubbles when agitated by the water pump, which can hinder heat dissipation from the water jacket walls. Scale: Calcium and magnesium ions in water can gradually form scale at certain high temperatures, significantly reducing heat dissipation capacity and partially blocking water passages and pipes, preventing normal coolant flow. Hazards: Engine components expand due to heat, disrupting normal clearance fits, affecting cylinder air intake, reducing power, and diminishing the lubricating effect of engine oil. Corrosion and Leakage: Ethylene glycol has strong corrosive properties on the radiator. As the corrosion inhibitors in the coolant degrade, they can corrode components such as the radiator, water jacket, water pump, and pipes.

The Dori G60s meets the China VI emission standards. More details about the Dori G60s are as follows: 1. The G60s is a brand-new model under the Dori brand, officially rolled off the production line on December 28, 2018. 2. In terms of exterior design, the new model adopts the brand's family-style design language, featuring a fashionable and bold appearance. The large fog light areas on both sides of the bumper significantly enhance the car's recognition. 3. The interior continues the family-style design, equipped with a full LCD instrument panel and a large central control screen, offering a strong sense of technology. 4. In terms of powertrain, the new model is equipped with a 1.5T and a 1.6L engine. The 1.5T engine delivers a maximum power of 110kW, and both engines meet the China VI emission standards. 5. The car measures 4523*1836*1682mm in length, width, and height, with a wheelbase of 2680mm. The parallel waistlines on both sides of the body highlight the car's three-dimensional feel. The front and rear tires feature five-spoke rims, emphasizing a sporty style. LED headlights come standard across the lineup. The gear shift mechanism is very similar to that of Land Rover, adopting a rotary knob design. 6. In terms of features, the new model is equipped with a multifunctional steering wheel, electronic handbrake, one-button start, automatic parking, automatic air conditioning, and many other practical functions.

How to Use Car Air Conditioning Correctly?

The correct methods for using car air conditioning are as follows: 1. When using the car air conditioning, never open the car windows, as this will increase the load on the air conditioning and cause its power consumption to rise sharply. 2. If you find that your car air conditioning seems ineffective during use, it indicates a problem with the air conditioning system. You should immediately turn off the air conditioning to prevent further damage and take the car to a repair shop. 3. Different car models have different methods for turning on the air conditioning. If your car does not have an automatic speed control device, you should not turn on the air conditioning system first. The correct method is to start the engine before turning on the air conditioning. 4. For automatic transmission cars, you should not turn on the air conditioning when driving at speeds of 120 km/h. Similarly, for manual transmission cars, avoid using the air conditioning at 110 km/h. This reduces the workload on the air conditioning and helps prolong its lifespan. 5. It's important to match the air conditioning's fan speed with the car's requirements. Also, pay attention to temperature control—avoid keeping the temperature at the lowest setting for extended periods, as this can damage the air conditioning chip. 6. In summer, monitor the car engine's condition when using the air conditioning. If the engine has been running for too long and overheats, turn off the air conditioning immediately to avoid affecting both driving performance and the air conditioning system. 7. Avoid using the car air conditioning when driving on dusty roads to prevent dust from entering the system. If necessary, set the air intake to the recirculation mode to block outside dust. 8. After using the air conditioning for an hour while driving, open the windows for at least 10 minutes to ventilate the car. This prevents the buildup of carbon monoxide, which can harm health and driving safety.

What are the reasons for Volkswagen EA211 idle vibration?

The reasons for Volkswagen EA211 idle vibration are: 1. Uneven cylinder pressure; 2. Excessive carbon buildup on intake valves and intake pipes, excessive dirt on throttle body and intake pipe inner walls; 3. Incorrect coolant temperature and intake air temperature signals, wiring faults; 4. Excessive spark plug carbon buildup or incorrect gap, leakage in high-voltage wires or distributor cap; 5. Fuel injector issues caused by excessive internal carbon deposits leading to poor sealing or clogging. The EA211 engine is a new automotive engine under Volkswagen, developed based on the Volkswagen transverse modular MQB platform, consisting of an exhaust camshaft adjuster and 5-hole injectors.
