Why does the Audi Q5 jerk when turning the steering wheel?

Audi Q5 jerks when turning the steering wheel because the power steering oil encounters resistance when passing through the high-pressure oil pipe during the process. The high-pressure oil pipe is a component of the high-pressure oil circuit, which requires the pipe to withstand certain oil pressure and have certain fatigue strength to ensure the sealing requirements of the pipeline. Automotive high-pressure oil pipes are mainly found in high-pressure injection diesel engines and direct-injection gasoline engines with high-pressure injection, capable of withstanding the oil pressure required during engine operation. The Audi Q5 is a mid-size SUV model under FAW-Volkswagen Audi, with dimensions of 4629 mm in length, 1898 mm in width, and 1655 mm in height, and a wheelbase of 2807 mm. In terms of power, the domestic version of the Audi Q5 is equipped with a 2.0-liter turbocharged engine, which has a maximum power of 169 kilowatts and a maximum torque of 350 Newton-meters.

Is it normal for the fan not to turn on at 90℃ water temperature?

It is abnormal for the fan not to turn on at 90℃ water temperature. When a motor vehicle's water temperature reaches 90 degrees, it indicates that the vehicle's radiator temperature has reached the normal operating level, and the fan should activate to lower the water temperature. Below is a detailed introduction to the car radiator (professionally known as the cooling system): Main components: The radiator is part of the vehicle's cooling system. In an engine's water cooling system, the radiator consists of three main parts: the inlet chamber, outlet chamber, main plate, and radiator core. Primary function: When the engine's water temperature is high, the water pump circulates water repeatedly to reduce the engine's temperature (the radiator is composed of hollow copper tubes. Hot water enters the radiator, is cooled by air, and then circulates back to the engine cylinder walls), thereby protecting the engine. In winter, if the water temperature is too low, the water circulation stops to prevent the engine from becoming too cold.

What problems can occur with the transmission of a flood-damaged car?

Once water enters the transmission, minor issues such as slipping, shaking, and rough shifting may occur, while severe cases may require transmission replacement. Below is an introduction to related issues concerning flood-damaged cars: Engine failure: Generally, if the engine compartment has been submerged, do not attempt to start the car, as it cannot be guaranteed whether the engine has taken in water. If water has entered, a secondary start could lead to connecting rod fractures in minor cases or complete engine failure in severe cases. Regardless of the scenario, the repair costs are extremely high, and the claims process may not go smoothly. Interior mold: The most challenging aspect of cleaning a flood-damaged car is the interior. Rainwater contains numerous impurities, and the soaked interior creates an extremely humid environment, making it highly susceptible to mold growth. If the vehicle is not dried promptly, mold can not only damage the fabric and leather materials inside the car but also produce various unpleasant odors.

How Often Should the Condenser Be Cleaned?

It is generally recommended to clean the car condenser every 2 years. Here are the relevant details:1. Function of the condenser: The high-temperature, high-pressure liquid refrigerant from the compressor becomes medium-temperature, medium-pressure refrigerant after passing through the condenser, which is then fed into the next-stage liquid storage tank or dryer. The process through the condenser is an effective cooling process. If the condenser fails, it may cause an imbalance in the pipeline pressure and lead to air conditioning malfunctions.2. Precautions: When cleaning the condenser, avoid using high-pressure water guns to prevent damage to the cooling fins or causing short circuits or failures in the electrical circuits. Also, remember to clean the gaps between the condenser and the radiator to avoid blockages. When cleaning the evaporator, it is best to use a specialized cleaner, spraying it from the air intake to allow the fine foam to penetrate deep into the air conditioning box and adhere to the surface of the evaporator for an extended period. This way, dirt can be thoroughly removed without the need for disassembly.

What are hazard warning lights?

Hazard warning lights are malfunction alert lights, commonly known as double flashers, technically termed as hazard warning lights. Below are common situations when hazard warning flashers should be activated: When the vehicle malfunctions: If a vehicle suddenly breaks down during road travel and cannot be promptly moved to a safe area, the hazard warning flashers should be immediately activated to alert passing vehicles and pedestrians for safety, and to promptly call for help while waiting for rescue. Breakdown on highways: When a vehicle breaks down on a highway, it should stop within the emergency parking lane, promptly activate the hazard warning flashers, and place a hazard warning sign 150 meters behind the faulty vehicle, then quickly call for help. The driver and passengers should wait for rescue outside the front guardrail of the faulty vehicle. When towing a malfunctioning vehicle: When towing a malfunctioning vehicle, as the vehicle is in an abnormal state, both the towing vehicle and the towed vehicle should simultaneously activate their hazard warning flashers. This alerts passing vehicles and pedestrians, especially those approaching from behind, to avoid sudden lane changes or failing to maintain a safe distance, which could lead to dangerous situations.

How to Align the Wiper Linkage Rod When Replacing It?

Method for aligning the wiper linkage rod during replacement: 1. Remove the wiper; 2. Turn the wiper switch to the first gear or push it upward once to let the wiper operate automatically and return to its original position; 3. Reinstall the wiper after it returns to position. The wiper is a blade structure installed in front of the windshield, consisting of a motor, reducer, four-bar linkage mechanism, wiper arm spindle, and wiper blade assembly. Its main function is to clear rain, snow, and dust that obstruct the view on the windshield. The power source of the wiper comes from the motor, which is the core of the entire wiper system. The wiper motor uses a DC permanent magnet motor, and the motor installed on the front windshield is generally integrated with the worm gear mechanism. The worm gear mechanism serves to reduce speed and increase torque, and its output shaft drives the four-bar linkage mechanism, converting continuous rotational motion into left-right oscillating motion through the four-bar linkage.
