How to Change the Transmission Oil for Audi A3?

This method is a root cleaning approach, which can also clean the oil filter. Removing the oil pan is a major task, and the corresponding labor cost will increase accordingly. Loosen the bottom nut of the transmission oil pan to allow the old transmission oil to drain naturally by gravity.
I've changed the gearbox oil for my Audi A3 several times myself. The process involves starting the car and letting it run for about ten minutes to warm up the oil, then parking and lifting the vehicle with jack stands for safety. Crawl under the car to locate the transmission drain plug, loosen it with a wrench, and let the old oil drain completely into a bucket. Clean the plug and wipe the area to prevent contaminants from entering the new oil. Before refilling, make sure to buy Audi's original specified transmission fluid—don't use random brands to avoid damaging the transmission. During refilling, keep the engine idling and slowly pour the new oil through a funnel, checking the oil level to meet the standard. Tools needed include a socket wrench, funnel, oil bucket, and gloves. The whole process takes about one to two hours and is suitable for drivers with some hands-on experience. Regular maintenance is crucial—do it every 50,000 to 60,000 kilometers to save money and extend the lifespan.
