DSG transmission requires transmission oil replacement. More details about transmission oil are as follows: 1. Any type of oil has a shelf life and needs to be replaced after a certain mileage or period of use. 2. Transmission oil is a lubricant that keeps the gear system clean, ensuring the normal operation of the transmission and extending the service life of the transmission device. 3. Transmission oil serves to transmit hydraulic power and provide cleaning and lubrication. If a car is used for a long time without changing the transmission oil, the oil particles may enlarge or generate debris, blocking the oil passages and potentially causing transmission failures. Therefore, transmission oil must be replaced regularly.

I own a Volkswagen Sagitar equipped with a DSG transmission. When it reached over 70,000 kilometers, I noticed some gearshift hesitation. After consulting a repair shop, the technician told me the fluid was long overdue for replacement. Unlike engine oil, DSG fluid doesn’t require frequent changes, but regular maintenance is essential because the dual-clutch structure relies on the fluid to lubricate gears, cool the clutch, and remove friction debris. Delaying fluid changes accelerates wear, leading to jerky shifts or malfunctions. That time, the fluid change cost me around 800 yuan, including the fluid and filter, and afterward, the transmission ran much smoother, almost like new. Now, I check the fluid condition every 60,000 kilometers and keep an eye on the dashboard for any warning lights. I recommend owners follow the manual’s suggested maintenance intervals—don’t wait until problems arise to regret it.

The DSG transmission certainly requires oil changes. As a technician who frequently services Volkswagen vehicles, I've encountered numerous failure cases caused by aged oil. The oil's role isn't just lubrication—it also aids in heat dissipation and hydraulic signal transmission. Prolonged intervals between oil changes can lead to sludge formation, clogging precision valve bodies and resulting in gear engagement failures or slipping. The standard replacement interval is typically 60,000 kilometers, but if you frequently drive in congested urban areas where high temperatures accelerate oil degradation, you should consider advancing this to 50,000 kilometers. Always use the manufacturer-specified DSG-specific oil and replace the corresponding filter during oil changes, as mismatches may cause issues. Professional shops employ machines to thoroughly flush out old oil, with labor and material costs typically under 1,000 yuan—far more economical than major repairs.

From a cost-saving perspective, investing in DSG oil changes is indeed worthwhile. Having driven a Volkswagen for ten years, an oil change costs around 600 to 800 yuan, and even budget-brand oil works fine. However, if you skip the oil change, transmission repairs can cost thousands of yuan. For example, deteriorated oil causing clutch damage would be a much bigger loss. Moreover, after an oil change, gear shifts become smoother, reducing jerky movements, and over time, fuel consumption slightly decreases, saving you dozens of yuan annually. It's recommended to get a minor service every 60,000 kilometers, and you can also check the manual to confirm if an oil change is needed—saving money while ensuring peace of mind.
