[SLWF30]

So, when I bought my F30 from the dealer last year, the A/C was really weak and I hadn't really noticed, as it wasn't overly warm out. The summer that year, I had no A/C in the car, and ended up getting it re-charged which fixed the problem through that summer and this summer. I know that these A/C systems aren't supposed to leak, and I'm wondering if maybe it had just leaked out the Freon by sitting for a so long without really being started (it was on the lot over a year before I got it, and it was used). Has anyone else experienced this?

On newer cars sitting for a year shouldn't affect the AC.

I have heard mechanics like Scotty Kilmer for example say something along the lines that it's normal for it to escape over time due to one of the shafts rides on a seal that gets lubricated with the PAG oil.

If you had a significant leak you would be able to see where the oil has come out with the Freon.

Granted your system was recharged and is fine it's safe to say it's not a big leak but doesnt hurt to get it checked out periodically.

There must be a leaking spot , check properly.
