whats up everyone. i own a 2.5 Z4.can anyone tell me which one of these is the low pressure a/c charge port? or where it is located.

Best wait for an A/C expert, but let me try my knowledge of thermodynamics.
High pressure side of compressor must go through pipe 2.
Hot compressed refrigerant then goes through condenser core, cools, and comes out pipe 3.
Condensate settles in accumulator and exits though pipe 4 to evaporator core, expands and cools, then back to compressor through assembly 14 and pipe 1. This would be the lowest pressure line in the system.
Looks like there's a charge port just to the left of the #14 balloon.
