What does 'Audi coolant pump 2 open circuit' mean?

Audi coolant pump 2 open circuit means there is a fault with a coolant pump that needs to be checked or replaced. Coolant pump 2 is an auxiliary water pump located not far from the main water pump, used for continuous heat dissipation after the car is turned off. Check the wiring harness and the small water pump. It is necessary to go to a 4S shop for inspection and repair. Below is additional information: Wiring harness: The wiring harness is directly connected to the engine computer via a plug without a fuse. The water pump of this car is installed under the intake pipe. The interface between the engine and transmission is located below the intake pipe. Replacing the water pump requires removing the intake pipe. Coolant: Coolant is an indispensable part of a car engine. It circulates in the engine cooling system, carrying away excess heat generated during engine operation, allowing the engine to operate at normal working temperature. When the coolant is insufficient, it will cause the engine water temperature to be too high, leading to damage to engine components. Therefore, once the owner finds that the coolant is insufficient, it should be added in time.

What is the BMW ICM Module?

BMW ICM module is an ignition module, also known as an ignition controller. Depending on different environmental requirements, it can be used in conjunction with metal probes or ultraviolet photosensitive tubes to achieve automatic ignition, flame indication, flameout alarm, and signal transmission. The ignition module features compact size, lightweight, strong ignition capability, and high sensitivity, making it widely applicable for monitoring flames generated by gases or liquids in various industrial applications, as well as for flameout protection. Additional details are as follows: Ignition module functions: After power is applied, the power indicator light (green) turns on. The switch has no power response in the ON/OFF state. When the switch is turned to ON, the system performs a self-check and ignites for 0.6 seconds before opening the solenoid valve. If a flame signal is detected, ignition stops, and the operation indicator light (yellow) turns on. If no ignition occurs within 10 seconds, re-ignition can be performed at any time during flameout. If a flame signal is detected during re-ignition, the system enters normal operation. If no flame signal is detected within 10 seconds, the solenoid valve closes, and the alarm indicator light (red) turns on. Ignition system: In the automotive industry, the ignition module, along with hybrid integrated circuits (HIC), ignition switch, ignition coil, and ignition distributor, forms the ignition system.

What type of oil does the Cadillac CT5 use?

The Cadillac CT5 model uses 5W30 fully synthetic engine oil with a replacement capacity of 6 liters and a service interval of 7,500 kilometers. The main functions of engine oil are as follows: 1. Lubrication and friction reduction: Forms an oil film between two sliding components to prevent friction during operation, ensuring smooth movement. 2. Auxiliary cooling: Absorbs heat from engine operation when oil reaches moving parts, then carries the heat away to assist in component cooling. 3. Cleaning: Carries away carbon deposits, sludge, and worn metal particles from engine components back to the oil pan through circulation, flushing contaminants from part surfaces. 4. Sealing: Creates a seal between piston rings and pistons to reduce gas leakage and prevent external contaminants from entering. 5. Rust and corrosion prevention: Adheres to component surfaces to protect against contact with water, air, acidic substances, and harmful gases. 6. Shock absorption: Cushions sudden pressure increases in engine cylinders that would otherwise heavily load pistons, piston pins, connecting rods, and crankshaft bearings, absorbing impact through lubricated bearing surfaces.

What do S-Class, A-Class, and B-Class mean in cars?

S-Class is the highest level of Mercedes-Benz sedans; A-Class (including A0 and A00) refers to small cars; B-Class cars are mid-range sedans. Below are relevant details about car classifications: 1. Basic Introduction: Car classifications originated from Volkswagen's method of categorizing cars in Germany. It is not an authoritative standard but rather a set of reference values Volkswagen initially established for its platform strategy, which later became widely used. Car classifications are generally divided into six levels: A00, A0, A, B, C, and D. 2. Classification Parameters: Level, wheelbase, vehicle length, engine displacement, and curb weight. A00-class passenger cars should have a wheelbase between 2 meters and 2.3 meters, with an engine displacement of less than 1 liter; A0-class passenger cars have a wheelbase of 2.3 meters to 2.5 meters and a displacement of 1 liter to 1.5 liters; A-class cars have a wheelbase ranging from approximately 2.5 meters to 2.7 meters, with a displacement of about 1.5 liters to 2.0 liters; B-class mid-range passenger cars have a wheelbase of approximately 2.7 meters to 2.9 meters, with a displacement ranging from 1.8 liters to 2.5 liters; C-class high-end passenger cars have a wheelbase of approximately 2.8 meters to 3.0 meters, with an engine displacement of 2.3 liters to 3.0 liters; D-class luxury passenger cars mostly feature a majestic appearance, extremely spacious interiors, and very powerful engines, with a wheelbase generally exceeding 2.8 meters and a displacement mostly above 3.0 liters.

What is the tire size of the Audi A8?

Audi A8 tire size is 255/40R19. The first number 255 indicates the tire width is 255MM, 40 represents the aspect ratio of the tire section is 40%, meaning the section height is 40% of the width, the letter R stands for radial tire, and 19 denotes the rim diameter is 19 inches. The Audi A8 has a top speed of 260km/h, accelerates from 0-100km/h in 6.3 seconds, and has a fuel consumption of 4.0L per 100km. In addition to the size, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings from 4.8km/h to 300km/h. Commonly used speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Indicates the rim size compatible with the tire for practical use, such as standard rim 5.00F.
