What type of coolant does the Audi A3 use?

I recently bought a used Audi A3 and I'm not sure what type of coolant to use. The manual just says to use the recommended coolant, but I can't find that information anywhere. Can anyone help?

According to the official Audi website, the Audi A3 uses G13 or G12++ coolant. Make sure to use a 50/50 mix of coolant and water for optimal performance.

I have an Audi A3 and I've had great results using the Pentosin G12++ coolant. It's specifically made for Audi and Volkswagen vehicles.

I work at an Audi dealership and we always use the G13 coolant for all our Audi A3s. It meets all the necessary specifications for optimal performance and longevity.
