How can I fix my Audi A1's air conditioning system?

I have noticed that the air coming from my Audi A1's air conditioning system is not as cold as before, and sometimes it emits a strange smell. Is there a way to fix this issue?

To fix your Audi A1's air conditioning system, you can start by checking the air filter and replacing it if necessary. A dirty or clogged air filter can affect the performance of your AC. After doing this, try cleaning the evaporator and condenser coils with a mild detergent and water mixture to remove any dirt or debris that may be causing the issue. Make sure to also check for any leaks in the system and have them repaired if found.
