Was the system originally R134a, or has it been converted from R12 at
some point? I know in the days of R12, VW used a slightly non-standard
fitting for the low pressure side, and I had a hard time finding an
adapter so that I could recharge it (with R12). I eventually found the
adapter at a larger auto parts store.
