How do I troubleshoot my Audi A3's malfunctioning air conditioning system?

My Audi A3's air conditioning system doesn't seem to be functioning properly. It's not blowing cold air and there is a strange smell. Can anyone provide some advice on how to fix this issue?

Have you checked the air filter and condenser for any build up of dirt and debris? This could be causing the issue.

I would suggest bringing your car to a certified mechanic to have it checked. It's important to address any AC issues promptly to avoid further damage.

One possible cause could be low refrigerant levels. You may need to have it recharged to get the AC working properly again.
