Why is the transmission fluid in the Envision turning white?

If the transmission fluid in the Envision turns white, it is due to water entering the transmission, which requires cleaning the transmission. Hazards of not replacing transmission fluid: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage to the transmission valve body. Transmission fluid is different from engine oil. Although both serve a lubricating function, their roles are distinct and should not be confused. Differences: Engine oil is the lubricant for the engine system, possessing properties such as oxidation resistance, anti-wear, and corrosion prevention. Transmission fluid, on the other hand, is primarily used to keep the gear system clean and extend the lifespan of internal transmission components. Because the structure and operating environment of the transmission and engine are different, transmission fluid cannot be used as engine oil, nor can engine oil be used as transmission fluid.

I've encountered several cases where the transmission fluid in the Envision turned white, mostly due to water ingress inside the transmission. When water mixes with the fluid, it emulsifies and turns white, resembling milk. Possible causes include radiator leaks, where issues with the coolant reservoir or related pipes allow water to seep in; or aging transmission seals that let water in during water crossings or rainy conditions; blocked breather vents causing condensation are also common. If not addressed promptly, the reduced lubricity of the fluid can lead to transmission overheating, sluggish gear engagement, or even slippage, ultimately damaging the gears. This is no minor issue—get it checked at a repair shop immediately. It's best to replace the fluid and filter, clean thoroughly, and fix any leaks. Regular maintenance should include checking fluid color and breather vents, and avoiding deep water crossings or flooded roads.

Does the Audi Q5 need spark plug replacement at 20,000 kilometers?

Audi Q5 does not require spark plug replacement at 20,000 kilometers. Audi Q5 spark plug replacement cycle: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is advisable to follow the user manual. You can refer to the following maintenance standards for replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000-80,000 kilometers. How spark plugs work: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block through the cylinder head. The insulator primarily serves to isolate the metal shell from the center electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the center electrode, it ionizes the medium between the center electrode and the ground electrode to generate a spark, thereby igniting the air-fuel mixture in the cylinder.
