What are the most common issues with the Audi A2's air conditioning system?

I have been experiencing some problems with my Audi A2's air conditioning and I am not sure what could be causing it. Can you give me some advice on what to check for and how to fix it?

There could be several reasons for your air conditioning issues in your Audi A2. You should first check if there is a leak in the system, as that can cause the coolant to run low and prevent the air conditioning from working properly. Another possibility is a faulty compressor, which is responsible for circulating the refrigerant and cooling the air. It is recommended to have a professional mechanic diagnose and fix the issue.
