Does the Magotan B7 dry dual-clutch transmission require fluid replacement?
3 Answers
No, the B7 is equipped with a dry dual-clutch transmission which is designed for lifetime maintenance-free operation. The manufacturer specifies that gear oil replacement is unnecessary. Transmission fluid serves to maintain cleanliness in the transmission system, ensuring normal operation and prolonging the service life of drivetrain components. Below are relevant details: Transmission Fluid: Depending on structural differences, transmission fluid can be categorized into manual transmission fluid and automatic transmission fluid (ATF). ATF functions both as hydraulic fluid and lubricant, operating in different vehicle systems. Regular Fluid Replacement: Owners should periodically change transmission fluid as prolonged use leads to viscosity thinning, resulting in reduced lubricity, compromised sealing performance, increased resistance, accelerated wear, pressure instability, and ultimately affecting hydraulic system precision.
I've been driving my own Magotan B7 for seven or eight years, and the dry dual-clutch transmission fluid definitely needs to be changed. When my car reached 50,000 kilometers, I felt some gearshift hesitation, so I took it to the shop for inspection. The mechanic said the fluid was already a bit dirty, which could affect the lifespan of the friction plates. After the change, the smoothness returned, and the car ran quieter on the highway. Transmission fluid is like the blood of a car—over time, impurities accumulate, and the lubrication effectiveness deteriorates. Especially in city traffic with frequent manual mode driving, the clutch wears out faster, and the fluid degrades more easily. Although the Volkswagen manual states that some models are labeled as maintenance-free, I recommend checking it at least every 60,000 kilometers or 4 years—don't wait for strange noises or failures to regret it. Regular maintenance costs just a few hundred yuan, avoiding major repairs that could cost thousands, and gives much more peace of mind while driving.
From a maintenance perspective, dry-type transmission fluid is not permanent. In my car enthusiast group, several owners of the Magotan B7 have reported issues—one drove up to 70,000 kilometers without changing the fluid, resulting in a transmission error that was costly and time-consuming to repair. The fluid serves to cool and lubricate; prolonged neglect can lead to carbon buildup and rust inside the transmission. Mild cases may affect acceleration smoothness, while severe cases can damage the clutch module. As someone who drives this type of vehicle, I prefer to keep detailed maintenance records and recommend changing the fluid every 50,000 to 80,000 kilometers based on driving habits. Highway-heavy drivers can stretch it slightly longer, but for stop-and-go city commutes, consider advancing it to 40,000 kilometers. Don’t blindly trust "lifetime maintenance-free" claims—real-world conditions vary, and regular changes are the safer bet. The fluid replacement process is straightforward, typically done at a repair shop within an hour, ensuring peace of mind and prolonging your car’s lifespan.
