Does the Passat dry clutch transmission require oil change?

[JudeFitz]

Passat dry clutch transmission does not require oil change. Volkswagen dry clutch transmission maintenance cycle: The manufacturer specifies it as maintenance-free, basically requiring no replacement. This is because the original factory-installed oil in this transmission is a low-viscosity fully synthetic gear oil with an exceptionally long service life, typically not needing replacement within 200,000 kilometers unless special circumstances arise. Replacement is only necessary if issues like water contamination or oil degradation occur. If replacement were required, the manufacturer would clearly specify the service interval. Function of transmission fluid: Transmission fluid primarily refers to the lubricating oil for gearboxes and rear axles. It differs from engine oil in terms of operating conditions, composition, and performance characteristics. Gear oil mainly serves to lubricate gears and bearings, prevent wear and corrosion, and assist in heat dissipation for the gears.
