Charged my system up a few days ago with 134a and everything works wonderfully. Only had to buy new fittings for my gauge set to fit the 1234yf fittings and the rest was routine. Less than $70, including buying the new fittings. Cheapest 1234 price I got, just to fill and not including mandatory diagnostic charge, was $500. I'll take the $70 fill every time over the other crap. So screw you hippies! ?
I just read this thread and can not believe how ignorant, selfish, and irresponsible you are. You should be ashamed of yourself for what you've done to your diesel and for putting 134 in your SUV.
