Does a 7-speed dry DSG require oil change?
2 Answers
7-speed dry DSG requires transmission oil replacement. Transmission Concept: Transmission mainly refers to the vehicle's gearbox, which is divided into manual and automatic types. Manual transmissions primarily consist of gears and shafts, achieving speed and torque variation through different gear combinations; whereas automatic transmissions (AT) are composed of torque converters, planetary gears, and hydraulic control systems, achieving speed and torque variation via hydraulic transmission and gear combinations. Transmission Functions: Altering the transmission ratio; enabling the vehicle to reverse while maintaining the engine's rotation direction; utilizing neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifting or power output.
Hey, as someone who's driven a Volkswagen for several years, I feel the 7-speed dry DSG is quite a topic worth discussing. Simply put, it doesn't require regular oil changes like a wet transmission because the dry design uses mechanical clutches without oil immersion, making it unnecessary. But don't think it's maintenance-free—the small oil seals or clutch module lubricants inside still need inspection and replacement, typically recommended in the manual around every 60,000 km, especially if you frequently deal with city traffic jams that can lead to overheating. Last time I asked a technician at the dealership, they said neglecting this could accelerate clutch wear, causing jerks or rough shifting. In short, while you save on oil changes, don’t skip checking the gearbox during maintenance to keep the drivetrain healthy. My car has run 50,000 km smoothly thanks to this habit, and even new drivers can easily follow this routine.
