You can use an a/c pressure gauge to check the low pressure port at the battery compartment to see if you have any pressure.

Unfortunately legally you need to bring the car to a shop to evacuate the refrigerant first before you can remove the fitting and replace the o ring.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi
Whilst replacing the AOS, I noticed a drip and wetness along a hard line. As far as I can make out from the parts diagrams, it is an A/C refrigeeant line? The leak probably between nr10 and nr25 in the parts diagram?
Is this fixable or is it a major PITA to fix? If it is just the o-ring nr18 can I disconnect and replace or will refrigerant flow out and is it dangerous. I would prefer to fix whilst I already have it in the air now than leave and have to come back later.
Any help appreciated
Mike
If these are the refrigerant lines, the refrigerant is under pressure at about 60 PSI depending on ambient temp so it will leak out and you may get frost bite. Unfortunately legally you need to bring the car to a shop to evacuate the refrigerant first before you can remove the fitting and replace the o ring. They also need to vacuum and meter refill it afterwards.
Are you actually losing refrigerant?
Does the A/C system work well, or has it been serviced in the last year or so?
Refrigerant is mixed with oil in the A/C system, so this may indeed be a leak as it appears oily.
As Ahsai said, the system is under pressure and the contents will escape if you open the system.
I forgot to add, the A/C makes a whining noise, so stopped using it a year ago. Suspected loss of refrigerant and have been searching for signs since. Haven't really focused bringing it to a shop...
So the fluid inside, should be emptied by pro's. That's cool.
But can anyone confirm it is an A/C line?
Are they the two black/silver lines at the very bottom of this photo?

Look like the refrigerant lines to me. Can you trace the silver part if they go up to the a/c compressor?
You can use an a/c pressure gauge to check the low pressure port at the battery compartment to see if you have any pressure. Maybe your refrigerant has leaked out completely already.
