[V6-12v] ac refrigerant question

Hello All,

The AC in my 1995 Audi 90 is not delivering cool air this spring.  I haven't
done any troubleshooting to speak of but I can say that the compressor is
not engaging when I hit the AC switch. This makes me suspect the low
pressure switch is being tripped.

My dilemma is I'm not sure which refrigerant the car is using.  It was built
in 06/94 but was in an front end accident prior to my purchasing the car in
2001.  Because of the accident, the condensor has been replaced and I can't
find any other place where the refrigerant type is listed.  It seems very
likely to me that the car has to have 134a because parts of the system was
rebuilt because of the accident, but I'd obviously like to avoid
contaminating the system by adding the wrong refrigerant.

So, does anyone know for sure what the car originally came with?  Bentley
was no help, it simply provided service info for both systems.

Thanks in advance for any help anyone can provide.
