How do I know when to change the transmission fluid in my Audi A1?

I recently bought a used Audi A1 and I'm not sure when the transmission fluid was last changed. I want to make sure I stay on top of maintenance for my car. How do I determine when it's time to change the transmission fluid?

According to Audi, it is recommended to change the transmission fluid every 50,000 miles. However, it may be wise to do it more frequently if you often drive in stop-and-go traffic or tow heavy loads.

One way to check if your transmission fluid needs to be changed is by looking at its color and smell. If it appears dark or smells burnt, it's time for a change. It's best to consult with a mechanic for a more accurate recommendation.
