Does the DSG dry dual-clutch transmission require oil change?
2 Answers
1. DSG dry dual-clutch transmission oil change standard: The DSG dry dual-clutch transmission requires oil change, which should be performed every 4 years or 60,000 kilometers, with 2L of gear oil needed for each change. Volkswagen offers two types of transmission oil: mechanical gear oil and transmission lubricating oil. 2. Introduction to gear oil: Gear oil primarily refers to the lubricating oil for the transmission. It differs from engine oil in terms of usage conditions, composition, and performance characteristics. Gear oil mainly functions to lubricate gears and bearings, prevent wear and corrosion, and assist in heat dissipation for the gears. Automotive gear oil is used in gear transmission mechanisms such as steering gearboxes, transmissions, and drive axles. Due to the high surface pressure during gear transmission, gear oil plays a crucial role in lubrication, anti-wear, cooling, heat dissipation, anti-corrosion and rust prevention, cleaning, and reducing gear surface impact and noise.
As a maintenance technician, I deal with various transmission issues every day. The dry-type DSG dual-clutch design is simple, with clutch plates directly rubbing against each other and no oil bath system, so it doesn't require regular oil changes. Manufacturers like Volkswagen state in their manuals that it's maintenance-free. However, there might be a small amount of lubricating oil in the clutch area, not the traditional gear oil. If the car experiences jerking or abnormal noises, it's best to check the control system's fluid condition and perform timely repairs to avoid major overhauls. Additionally, faults in the electronic control unit can lead to misoperations. For long-term use, monitoring is far more important than blindly changing oil, as it's both cost-effective and practical. The core of maintenance is to regularly visit the 4S shop for system inspections, approximately every two to three years, and not to overlook the manual's recommendations.
