[OTO335i]

I was wondering if someone could take a look at their cap for the schrader valve on the low side of the AC lines? My high side cap has an O-ring inside of it and my low side cap doesn't. I wonder if there should be one in it as well?

I looked on real oem and they don't list the O-rings for the caps.

Id really appreciate it if someone could take a look or if you simply know to let me know.

Thanks

Mitch

Oh now I see the attachment. Strange I cannot see your link on the APP but I have access to it on the computer. Unfortunately the document doesn't give the break down of the parts at the service port so I can't tell if it indeed requires an o'ring or not..

I would just need someone to physically check if theirs has one if possible.

I’d be happy to take a look. Will post with my findings. That said, I doubt the o-rings on these dinky caps do much, so probably not a big deal if yours is missing.

Thank you, i really appreciate it! I agree, it probably doesn't do much and i do not believe my leak is that location. It's mostly my OCD kicking in and wanting things to be as they should be lol

Small purple gasket under both caps on my 328i.

Looks like you have your answer!

I am certain the lack of gasket has nothing to do with your leak.

Nonetheless, it looks like a cheap replacement: $2.41 to be exact...

I totally agree, I'm very certain it's not the cause of my leak, I'm pretty sure it's my evaporator.

Thanks again man!
