A friend of mine is putting freon in my 525i and wants to know which side is the low side suction to the AC? I know I worded this wrong but give me a break, I can saddle a horse but can't change a tire!!!

usually the low side hose is larger...it is between the compressor and the firewall..

The low/suction side is always the larger diameter piping because it carries gas not liquid. The fitting are also different so as to be foolproof.
