The replacement interval for the transmission fluid in the Tiguan 1.8T is 55,000 kilometers. Below are the methods for replacing transmission fluid: 1. Gravity replacement: Use tools to loosen the nut, and the transmission fluid will automatically flow out under gravity. 2. Circulation machine replacement: Store new transmission fluid inside the circulation machine, connect the machine's pipes to the transmission's oil circuits, and under hydraulic pressure, the new fluid will push out the old fluid. This method cleans the oil circuits more thoroughly. 3. Oil pan removal replacement: This method cleans from the root, making it more thorough, and also allows for cleaning the transmission fluid filter.

Having driven Volkswagen cars for twenty years, my experience tells me that the transmission oil change interval is quite crucial. The official manual for the Tiguan 1.8T recommends changing the oil every 60,000 kilometers or four years. However, based on actual driving conditions, if you frequently drive short distances in congested urban areas with constant stop-and-go traffic, the oil will degrade faster. I suggest shortening the interval to 50,000 kilometers for better maintenance. When the oil ages, its lubrication effectiveness diminishes, leading to increased wear and tear on the internal gears of the transmission. Once a failure occurs, repairs can easily cost several thousand dollars. I’ve personally experienced the consequences of not changing the oil on time—my car started jerking during gear shifts on the highway, and it cost me over 3,000 yuan to fix at the repair shop. So, car owners should adjust the interval based on their driving habits and regularly check the oil level or have it evaluated by a professional shop. Although this is a small expense of a few hundred yuan, it’s well worth preventing major issues, especially for older vehicles.

Engine oil is an essential item that every car owner needs to deal with during vehicle use, and it is often referred to as the lifeblood of the engine. If there is no engine oil in the engine, the car's engine cannot operate normally. Here is some additional information: The functions of engine oil: Inside the engine, engine oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. The function of the engine oil filter: It filters the engine oil. Without the engine oil filter, the engine oil would become very dirty after some use, which would affect the engine's lubrication and heat dissipation.

What Causes Car Jerking at Low Speeds?

Car jerking at low speeds may be caused by a dirty throttle body. The throttle body regulates the air intake, which affects the car's driving performance. Below is a detailed introduction to the car throttle body: 1. Overview: The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. The throttle body is connected to the air filter at the top and the engine block at the bottom, often referred to as the "throat" of the car engine. 2. Function: The throttle body is one of the most important components in today's electronic fuel injection engine systems. The upper part connects to the air filter, while the lower part connects to the engine block, serving as the "throat" of the car engine. The responsiveness of acceleration is closely related to the cleanliness of the throttle body. Cleaning the throttle body can reduce fuel consumption and make the engine more responsive and powerful.

Is It Dangerous to Drive a 10-Year-Old Car on the Highway?

As long as the vehicle has complete documentation and is in good condition, there should be no issues. Below is an introduction to potential dangers on the highway: 1. Random Lane Changes: The average speed on the highway is relatively high. When changing speed, it is essential to strictly follow the principle of signaling, checking the rearview mirror for three seconds, and then turning the steering wheel. Random lane changes in high-traffic areas not only put you in danger but also disrupt the normal flow of other vehicles, leading to collisions or rear-end accidents. In low-traffic areas, even though there are fewer cars, avoid unnecessary lane changes—first, there's no need to change lanes if there are no cars ahead, and second, high speeds can make the vehicle unstable during lane changes. 2. Proximity to Large Vehicles: Compared to urban roads, highways have more large trucks, hazardous material transporters, and buses. If a large vehicle approaches, even skilled drivers should overtake or change lanes to maintain distance. If overtaking isn't possible, slow down to let the large vehicle pass. If following a large vehicle, always maintain a safe distance, as a collision between a small car and a large vehicle can be catastrophic for the smaller car due to the size difference. 3. Sudden Braking or Stopping: Avoid rapid deceleration or stopping on the highway unless absolutely necessary. High speeds require quick reactions from other drivers, and sudden braking or stopping can lead to rear-end collisions. If there's no emergency, use gradual braking to slow down. In case of an emergency, pull over to the emergency lane before stopping. 4. Speeding: While highways allow high speeds, they do not permit exceeding the speed limit. Highway speed limits typically range from 60–120 km/h, varying based on terrain and road conditions.
