Buy a kit at Wal-Mart or auto parts comes with instructions While the equipment to install refrigerant is widely available, I try to discourage the practice for a few reasons: System charges are very specific...too much and your compressor will run too hot. Too little, and the lubrication to the compressor will be affected. Either means a short life span for the compressor, and a future expensive repair. Refrigerant is a controlled gas, and it is illegal to vent it to the atmosphere. Refrigerant acheives very low temperature at atmospheric pressure and can hurt you. If there is a mechanical problem, adding refrigerant won't help. If there is a leak, adding refrigerant won't last long. Please, have a professional help you.
The Auto button will turn on the AC then set your desired temperature.

To turn on the AC in a 2003 Audi A6, first, ensure the ignition is on. Then, locate the climate control panel on the center console. Press the "AC" button, which will illuminate to indicate that the air conditioning is active. Adjust the temperature and airflow settings as desired for optimal comfort.
It's the schrader valve on the low pressure side of the system. Find the AC compressor. There are two hoses coming out of it - one is larger than the other. That's the low pressure hose. Trace it back until you find the scrader valve - it's usually topped with a plastic cap.
R134 is used, but have the leak fixed first.

Yes, you can bypass the AC compressor on a 2003 Audi, but it requires careful consideration. This typically involves using a shorter serpentine belt to connect the crankshaft pulley directly to the alternator and other accessories, effectively omitting the AC compressor. However, it's important to ensure that this modification does not affect other systems and that the vehicle remains safe and functional. Consulting a professional mechanic is recommended before making such changes.
I assume there are service valves somewhere on the unit. Unless theyve got some new advanced way to charge it?
if both readings are about the same 100's most likely tou have a bad ac compressor
