How do I troubleshoot the air conditioning in my Audi A1?

I've noticed my air conditioning in my Audi A1 isn't working properly, and I can't seem to figure out why. The air blows slightly cool, but not cold enough to make a significant difference. What could be the issue and how can I fix it?

First, check to see if your A/C system is low on refrigerant. This is a common cause of poor cooling in cars. If this is the case, take your Audi to a mechanic to have the refrigerant recharged. It's a fairly simple and inexpensive fix.
