AC stopped working last night and today I tried recharging the AC system and noticed this leak. I was wondering if I could change the valve instead or JB Weld this leak or I had to order a new hose? If so does anyone know the part number and have a tutorial on changing this part? It's the High Pressure Hose towards the front of the N54 2009 335i

The area where it is leaking should be an oily mess, but I don't see anything that is oily.

Yes that's because the Oil Lines are not leaking just the High Pressure AC line. Just wondering if anyone had a video on how to replace this AC hose ?

Just trying to understand the picture. Is the green thing fluorescent dye coming out from the aluminum pipe? Or from the bottom of the high pressure port connector?

Some high pressure port connectors are replaceable. I am not sure if this one is. Either way it looks like a dealer only part and needs to changed.

And I think that is a $167 liquid line. It goes from the passenger side back to the firewall, and crosses over to the driver side. You can talk to a local AC shop and see if the port valve can be replaced by itself. They may be able to use a flared tube repair port, but that might not have much of a price advantage to replacing the liquid line.
