After reading the nearby bit about changing the AC compressor and Dave's story about his leak, I wanted to mention my situation. 1994 N/A, purchased in 2007. Daily driver, must be near to 400K on it. Almost every year I bring it to a local who is willing to recharge the freon. It is about the only thing I need his help with thanks to this group. Thru the years I have also had trouble keeping the climate control switch unit fully functional, so Ive had to buy some working used ones.

Anyway, every year since 2008 he drains the freon, finds that the car holds a vacuum and then refills the correct amount of freon. He finds the freon level down by 50% to 80% each year, but the system works well, given the electrics are working.

He says something is leaking; I even thing he put some die in it many years ago. We just keep it running this way and for $120 a year, it's worth having the relationship and a pro taking care of my AC in both 940's.

All my red blocks are so cheap to own and run. It's been a great solution! I'll probably keep the 30 year old car on the road until something comes up I can't handle. Rolling the dice on the AC system at this point seems too much.
