Howdy all.
I bought my current 525i two years ago, at which time, the seller told me the AC needed a recharge but should work. I didn't completely believe him and at the time I was more concerned about winter operation. So, 2 years later, I'm considering trying to recharge it, but I wonder if I should first replace certain seals that have most likely dried out by now. Don't know much about AC, but I always hear people warning about dried seals. Is it common to just replace seals?
Also, can the shop pump in that leak detector dye without putting any refrigerant in the system? I'm hoping that, by some miracle, I can revive the AC without spending more than $100.
