To clear up confusion. Do Audis have accumulators or receiver-driers? Do
Audis have expansion valves or an orifice tube?

I did a full conversion to R134a on my 4000 several years ago,
and while it wasn't the most economical way to go about it,
I have absolutely no regrets.  It's still working better than new.

- Swapped to Sanden compressor with special adapter bracket
- New R134a-compatible barrier hoses, fittings, ports and nitrile o-rings
- New receiver/drier
- New expansion valve
- Radiator fan upgrade
- A/C Idle boost valve upgrade
