1996 a4 looking for the low side port for ac, where is it at?? they can't be that dumb to only put a high side port! I'm thinking that there must be a special tool that adapts to the low pressure sensor that only audi has?? PLEASE HELP SOMEONE MUST KNOW thanks!!! MIKE[:'(]

 

sorry dude...i just found out a couple days ago that audi did indeed leave out a low side port....you're probably gonna have to take it to a shop...

 

Thanks for the response! I recharge alot of ac units and i know there has to be aspecial tool that audi uses where the low pressure switch screws on by the pollen filter ... anyone???? thanks again

 

i'd like to know about this tool as well.....anyone have one they wanna rent out??
