What precautions should be taken when disconnecting the battery and replacing the A/C compressor on 2019 Volkswagen Golf?

Some systems require re-learning after the battery has been disconnected. Install the compressor instead of refrigerant desiccant cartridge. Turn off the AC system, remove the engine cover and un-connect the battery. Turn off the compressor, clean off the fittings and fit a new fitting with the correct oil. Evacuate, recharge and leak test the system.
