Default 1994 100s A/C question

Does anyone know if the 1994 100s (non quattro) air conditioner used r134A or the older stuff? The a/c on my car needs a charging, and I don't want to get reemed by the dealship if at all possible.

And another thing...does anyone know where I can find a Bently manual for this car?

Thanks so much.

you can refill a134 yurself and save a bunch of bucks ... get a couple cans of a134 with some kleeners inside (there is coolant refills with all kinds of additives) charge half way or to 3/4 of capacity run it through thouraly and then charge up all the way

The audi conector is not quick plug. So you need to get an adapter.
a full system is about 8oz and 8oz of PAG oil.
use R134a. or equvalent, there is R14 and higher ones that can blend easilly. dont use R12 as its bad.
I charged it my self, without getting air out, and its running okey.
u charge it as car runs and AC on.
my procedure is to put oil first, after that I start to put gas in. about after couple of seconds, it should be enough to start the AC compresor, and the sysetm will start to suck the thing in.

oh, oil use lowest viscosety, like 46 or something. There is 3 of them 46 100 and 150, use lowest. . it has to be PAG.
when fueling put it up side down, couse oil is need in liquid form. It is used as a coolant for parts, and as a sealant.
it should be about 30psi there or so.

I get 16F when it runs on 1st speed, and set to max, during a 90F day.
I say its freazing ***** cold.
I have to set AC hotter, using my heater, and setting the AC to min.
