Old Jetta cars shake when starting due to dirty throttle bodies or fuel injectors, causing engine vibration during operation. It is recommended that the owner clean the carbon deposits. The accumulation of carbon deposits and dirt on the throttle body and fuel injectors leads to a decrease in power, resulting in car shaking during idling and starting. Jetta is a joint venture of the German Volkswagen Group in China and is a car brand under FAW-Volkswagen Automotive Co., Ltd. Its first product, the Jetta, was launched in Europe in 1979. Structurally, the Jetta is essentially a Golf with an added trunk, making it a derivative model of the Golf.

What are the buttons inside the Buick Excelle?

Buick Excelle interior button instructions are as follows: 1. Electronic Stability Program (ESP): The system is enabled by default. Unless driving on slippery surfaces like rain or snow, it is generally not recommended to turn it off. 2. Auto Start-Stop: At traffic lights, the engine is temporarily shut off. When the driver's foot leaves the brake pedal, the vehicle will restart. 3. Recirculation/Fresh Air: Recirculation heats or cools the air inside the car and sends it back in, while fresh air brings outside air into the car. Use recirculation in traffic jams, tunnels, or when outside air quality is poor. On highways, switch from recirculation to fresh air periodically; recirculation should not exceed one hour. 4. Temperature Zone Sync (some models): When the temperature zone sync function is turned on, changing the driver's side temperature will cause the same change in other zones. Turning off this function allows each zone to be set individually to meet the needs of passengers in different positions.

Where to Add Windshield Washer Fluid for Magotan?

The windshield washer fluid for the Volkswagen New Magotan is added in the reservoir located in the engine compartment. Here is some relevant information about automotive windshield washer fluid: 1. Function of automotive windshield washer fluid: It is formulated with various surfactants and additives, providing functions such as wetting, penetration, and solubilization to effectively clean and remove dirt. It significantly lowers the freezing point of the liquid, offering anti-freeze properties and quickly dissolving frost. It prevents the formation of fog droplets, ensuring clear and transparent windshields with unobstructed visibility. It also eliminates static charges on the glass surface, providing anti-static properties. Additionally, it acts as a lubricant, reducing friction between the wipers and the glass to prevent scratches. It thoroughly removes dust and stains from smooth surfaces, leaving them shiny with just a wipe—no rinsing required, no water streaks, long-lasting cleanliness, and no damage to the surface. It offers dust-proof, anti-fog, and anti-freeze functions, minimizing dust adhesion. 2. Types of automotive windshield washer fluid: In northern regions, choose anti-freeze windshield washer fluid to prevent the pipes from freezing and cracking before the fluid is used up in winter. In southern regions, windshield washer fluid with added insect remover components is sufficient. 3. Dilution of automotive windshield washer fluid: Most windshield washer fluids need to be diluted before use. Simply follow the instructions on the product manual. The capacity of a car's windshield washer fluid is approximately 1.5L, so a container with a capacity of 1.25L to 1.5L is suitable for dilution. 4. Adding automotive windshield washer fluid: There is a reservoir on the left side of the engine compartment with a cap marked with a windshield washer symbol. Open it and pour in the diluted anti-freeze windshield washer fluid, but do not fill it to the brim. It is sufficient to just see the water surface at the deepest point, and do not exceed the MAX mark.

Why do the hazard lights still flash when the car is turned off?

As for the issue of the driveshaft leaking oil, it is necessary to go to a repair shop for inspection and treatment. Whether it needs to be replaced depends on the specific situation. The following is a detailed introduction: 1. Driveshaft: The driveshaft is the shaft in the universal transmission device that can transmit power. It is a high-speed, low-support rotating body, so its dynamic balance is crucial. Generally, driveshafts undergo dynamic balance tests before leaving the factory and are adjusted on a balancing machine. For front-engine, rear-wheel-drive vehicles, the driveshaft transmits the rotation from the transmission to the main reducer. It can consist of several sections connected by universal joints. The driveshaft is composed of a shaft tube, a telescopic sleeve, and universal joints. 2. Assembly of various components: The driveshaft connects or assembles various components, and the circular moving or rotating parts are made of lightweight and torsion-resistant alloy steel tubes. For front-engine, rear-wheel-drive vehicles, it transmits the rotation from the transmission to the main reducer and can consist of several sections connected by universal joints. It is a high-speed, low-support rotating body, so its dynamic balance is crucial. Generally, driveshafts undergo dynamic balance tests before leaving the factory and are adjusted on a balancing machine.
