How often should the CVT transmission fluid be replaced in an Audi A4L?
2 Answers
Audi A4L requires CVT transmission fluid replacement every 60,000 kilometers. The steps for replacing transmission fluid are: 1. Remove the drain plug at the bottom of the transmission to drain the old fluid; 2. Remove the inner and outer transmission housing; 3. Remove the transmission fluid filter; 4. Take off the oil pan gasket and clean surrounding contaminants; 5. Wipe the cleaned transmission fluid filter with cotton yarn; 6. Add new fluid. Taking the 2020 Audi A4L 35TFSI Fashion Dynamic model as an example: It is a mid-size 4-door 5-seater sedan with dimensions of 4858mm in length, 1847mm in width, and 1439mm in height, a wheelbase of 2908mm, and equipped with a 7-speed dual-clutch transmission.
To be honest, I've been driving an Audi A4L for over six years and know quite a bit about CVT transmission fluid changes. Generally, Audi recommends replacing it every 60,000 to 80,000 kilometers, or having it inspected every four years or so. It really depends on your driving habits—if you're frequently stopping and starting in congested city traffic, like during daily rush hours, the fluid may degrade sooner, so changing it at 60,000 km is safer. Don't delay too long, or the fluid can thicken or accumulate contaminants, affecting transmission smoothness. In severe cases, you might end up needing costly major repairs. Last time I forgot to change it on time, the gear shifts became noticeably jerky, and I had to get it checked at a professional shop—cost a bit but saved me headaches. I recommend following the manual's maintenance schedule rather than relying on intuition.
