I assume there are service valves somewhere on the unit. Unless theyve got some new advanced way to charge it?

To vacuum the AC lines on a 1997 Audi Quattro, first, connect a vacuum pump to the high and low service ports of the AC system. Make sure the system is off, and then run the vacuum pump for at least 30 minutes to remove moisture and air. Afterward, close the valves on the pump and check for any leaks. Once the vacuum holds steady, you can proceed to recharge the AC system with refrigerant.
By buying an AC charge hose and a can or 2 of R134a freon (depending on how much your car needs) Attach hose to the low pressure side & charge system. Do not overcharge, or you may destroy the AC system.
Because it probably has a leak if you have just fixed a leak then you need to put a vacuum on your AC system before you can charge it.
You will not be able to charge the system correctly plus you will have moisture stuck in the system.....
Not the high side.
It is on the accumulator.
To replace the AC compressor on an Audi A3, first, disconnect the battery and remove any components obstructing access to the compressor, such as the front bumper or engine cover. Next, discharge the AC system properly, then disconnect the refrigerant lines and electrical connectors from the compressor. Unbolt the old compressor, install the new one, reconnect the lines and electrical connections, and recharge the AC system with refrigerant. Finally, reassemble any removed components, reconnect the battery, and test the AC system for proper operation.
To turn the AC on and off in an Audi TT, locate the climate control panel, which is usually situated in the center console. Press the button labeled "AC" to activate or deactivate the air conditioning system. You can also adjust the temperature and fan speed using the corresponding dials or buttons. Make sure the vehicle is running for the AC to function properly.
if both readings are about the same 100's most likely tou have a bad ac compressor
