What is the cause and solution for the air conditioning problems in Audi A2?

I have been experiencing issues with the air conditioning in my Audi A2. The cool air is not as cold as it used to be and sometimes it doesn't turn on at all. What could be causing this and how can I fix it?

The most common cause for air conditioning problems in an Audi A2 is a low refrigerant level. It's important to have your refrigerant level checked and topped up if needed to ensure optimal cooling performance.

Another possible cause could be a faulty compressor, which can cause inconsistent or no cooling. It's best to have a professional check and replace the compressor if necessary.

Make sure to regularly replace the cabin air filter as a dirty filter can reduce the efficiency of your air conditioning system. It's recommended to replace the filter every 12,000 miles or as stated in your vehicle's manual.
