First, check the refrigerant level in your A4's AC system. Top it up if necessary, and make sure there are no leaks. If that doesn't solve the problem, it could be an issue with the compressor or other mechanical components.

Another potential cause of a faulty AC could be a faulty condenser. If this is the case, consider replacing it to regain proper performance from your Audi's air conditioning system.

Sometimes, issues with the AC are caused by electrical problems. Check the fuses and relays related to the AC system and replace any that are damaged or worn out. This could save you from an expensive repair.
