Where is the transmission fluid inspection port on the Passat?

The transmission fluid inspection port on the Passat is located on the right side at the rear of the transmission. Signs that indicate the need for transmission fluid replacement include: vehicle shaking, gear shifting hesitation; transmission overheating warning on the dashboard; engine stalling; and unusual noises. The methods for replacing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the old fluid before refilling. Remove the transmission oil pan directly for draining and refilling: This method is more thorough than the previous one, as it allows for the removal of debris at the bottom of the oil pan. Use a circulation machine to replace automatic transmission fluid: Dynamic fluid replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission. Hazards of not replacing transmission fluid for a long time: 1. Damage to the transmission's gear shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impaired normal operation of the transmission, leading to damage to the transmission valve body.

What Causes the Sharp Noise from Mercedes Brakes in Winter?

The reason why Mercedes-Benz cars make sharp noises when braking in winter is that during driving, particles such as rust enter the brake discs, causing friction and noise; or the car has not been maintained for a long time, and the brake discs have hardened, resulting in noise. The solutions for Mercedes brake noise are to check if there are any foreign objects on the brake pads. If foreign objects are found, they need to be removed; check if the brake pads are severely worn or if the attachments are loose. If so, new brake pads need to be replaced; if the noise occurs during the break-in period of a new car or after replacing the brake pads, it is a normal phenomenon, and the noise will disappear after the car has been driven for a certain distance. Regarding the maintenance and care of the brake system, it mainly includes regularly inspecting the brake pads. If the brake pads and discs are worn to a certain extent, they must be replaced. Generally, it is best to check every 10,000 kilometers; regularly replace the brake fluid, as deteriorated brake fluid can affect braking performance; during the break-in period of a new car, try to avoid emergency braking; while driving, try to avoid frequent braking; do not disassemble the brake system privately to avoid loosening. Regularly clean the brake discs.

How Often Should the Intake Valve and Throttle Body Be Cleaned?

Throttle bodies generally need cleaning every 20,000 to 30,000 kilometers, but there is no strict standard—they can be cleaned when dirty. If there is oil accumulation or carbon buildup in the throttle body, it is necessary to promptly visit a 4S shop or repair shop to clean the throttle body. Below are the specific reasons for a dirty throttle body and precautions to take: Specific reasons for a dirty throttle body: A clogged intake passage can cause idle fluctuations, and carbon deposits or oil accumulation in the throttle body are the most common causes of unstable idling. Carbon buildup in the throttle body affects its opening, which in turn affects the air intake volume, causing the engine speed to fluctuate erratically during cold starts, accompanied by strong vibrations. Precautions for a dirty throttle body: Severe oil accumulation or carbon buildup in the throttle body, including a dirty intake passage, can make it difficult to start the car in cold weather. A dirty throttle body should be cleaned, as throttle body cleaning is considered a routine maintenance task. Spark plugs can also accumulate carbon deposits, which can be cleaned to restore their performance.

How many cylinders does the S90 have?

The Volvo S90 is equipped with a four-cylinder engine. The domestic version of the model comes with two engine options: one is a low-power version of the 2.0-liter turbocharged engine, and the other is a high-power version of the 2.0-liter turbocharged engine. In terms of power, the new S90 is equipped with a high-power version of the 2.0T engine paired with a 48V mild hybrid system. It delivers a maximum power of 184kW (250 horsepower) and a peak torque of 350Nm. The transmission is an 8-speed automatic gearbox. Additionally, the T8 E-AWD hybrid model features a plug-in hybrid system composed of a 2.0T mechanical + turbo twin-charged engine, front and rear dual motors, an 8-speed automatic gearbox, and an 11.6kWh battery pack. The new S90 retains the styling design of the overseas version, with a more refined front fascia. The vertical grille, combined with the chrome trim strip running across the front bumper, exudes a sense of sophistication while enhancing the overall recognition of the front end. The rear features full LED lighting with sequential turn signals, offering higher visibility at night.

What is the function of engine sensors?

Engine sensors have the following functions: 1. Air flow sensor: Measures the amount of air entering the engine and is installed on the air bypass channel; 2. Intake pressure sensor: Detects changes in the negative pressure of the intake manifold to determine the engine's air intake volume; 3. Engine speed and camshaft position sensor: Used to measure engine speed and confirm the crankshaft position signal; 4. Throttle position sensor: Includes a linear throttle potentiometer and an idle switch. The former provides the ECU with data to control fuel injection volume and ignition timing, while the latter informs the ECU when the throttle is in the idle state; 5. Coolant temperature sensor: Measures the temperature of the engine coolant; 6. Intake temperature sensor: During engine operation, the mass of air entering the engine is related to the intake temperature and atmospheric pressure. When the intake temperature is low, the air density is higher, resulting in a greater mass for the same volume of gas. Conversely, when the intake temperature is high, the mass of the same volume of gas is smaller; 7. Knock sensor: Detects whether the engine has a knocking phenomenon; 8. Oxygen sensor: Measures the oxygen content in the exhaust gas; 9. Vehicle speed sensor: Measures the vehicle's driving speed.

What type of spark plugs does the Geely Binrui use?

Geely Binrui uses Bosch (BOSCH) specialized iridium spark plugs. Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body, known as a "spark." Along with the heat expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach 2000–3000°C, which is sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber. Steps for replacing spark plugs: Open the engine hood, lift the plastic engine cover, remove the high-voltage ignition wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris such as leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires in the firing order and secure the cover.
