Replaced my A/C compressor the other day. Can anyone verify the R134 capacity of the Jetta TDI A/C system? I've heard 2 different figures - 24 ounces and 41 ounces.

Anyone know for sure?

See pictures of my mangled compressor clutch in the A4 maint. forum.

I would expect that there is a pressure switch that keeps the compressor from running if the ref. level is low. It is designed to keep it from running if it can't circulate the oil. If the ref. is only slightly low, the compressor short-cycles because of this switch. There should also be an anti-ice switch on the evaporator, which controls the compressor.
