Audi doesn't provide a low pressure charging port, they have a kit that the dealer must intsall to allow charging of the system

Where is the low pressure port located?

if your are looking for the air conditioner Freon low side port i can only assume that your trying to recharge your ac yourself. DO NOT DO IT!! i work on cars professionally. the only way to properly charge your ac is to evacuate first under vacuum to eliminate all moisture from the system. if you have any moisture in the system and you run it it will cost you thousands of dollars instead of the hundred it would cost to have a professional do it. if the Freon cans worked well mechanics would use them instead of buying thousands of dollars worth of machines to do it.

What kind of freon to put in a 1993 audi?

Do you have a sticker on the inside of your hood of your car? It should list the type of freon you need, if not if you have the owners manual it will give you that information also........the only thing i am obligated to ask you by law, is are you licensed to recharge the cooling system in your car? If not it is a violation of federal law for you to recharge your cooling system. You must be trained properly to do so........if you are not then you have to have it done at a garage who is licensed to do so..........

AC is not working

Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
