Where is the low pressure ac recharge port on a 2001 beetle 2.0L?

On a 2001 Volkswagen Beetle with a 2.0L engine, the low pressure AC recharge port is located on the passenger side of the engine bay. It's typically found near the firewall, on the larger AC line, which is usually insulated with a rubber or foam cover. Look for a blue or black plastic cap; this is the port where you can connect your refrigerant recharge kit. Always ensure the engine is off and the AC is set to the maximum cool setting before recharging.
