A/C charging

I ended up recharging my X3 AC. So far so good. Going on 2 months.

Nothing special to adding. Just watch pressure!

As edjack mentioned there are lots of posts on this topic.
As a first step, browse through the sticky "the VERY best of E39 Links" at the top of the first page of this forum.

I recommend you pay particular attention to those pointing out the risks one runs by recharging without weighing the total charge. Keep in mind that the characteristics of refrigerants such as R134a are such that you may inadvertently overcharge without harm on a hot day when a large proportion of the R134a is in the gaseous state. Days, weeks or months later, cooler ambient temperature could easily result in too much of the charge being in a liquid state and cause a slug through the compressor which would destroy it.
