I have a 2018 A5 Sport back. Recently the AC switch stays on A/C off and when I try to toggle it to on it doesn't change on the digital screen.
The car wont produce cold air because of this problem.
Any ideas as to what this could be?

Thanks!

Have your car scanned with a proper VAG-aware diagnostic tool (e.g., ODIS, VCDS, OBDeleven, etc) and report any DTC/fault codes from Address 08 - Auto HVAC. Could be a failed high pressure sensor or a refrigerant leak in the system. --g

Thank you so much for the advice.
I scheduled going in, but with wait times I wont know until the 13th of June.
Thought Id check for any common quick fixes.

Harry. At that age the car will need an aircon service which costs about 100 bucks. They connect a machine which empties your gas tests the vacuum and then fills with new gas and oil. Change the pollen filter and you are good to go.
