Mercedes-Benz transitioned from R-12 refrigerant to R-134a refrigerant in the early 1990s. The change was primarily due to environmental concerns regarding the ozone-depleting properties of R-12. Specifically, by 1993, most new models were equipped with R-134a as part of the automaker's commitment to more environmentally friendly practices.

No you don't have to change the A/C Compressor.
There is no need to ever change the refrigerant which is R134 and not Freon R12.
The type of refrigerant that an E 34 needs is R12 refrigerant. It is absolutely necessary that you do not put any other type of refrigerant into a R12.
The 1980 Mercedes-Benz 300D originally used R12 refrigerant in its air conditioning system. However, due to environmental regulations and the phase-out of R12, many owners have retrofitted their systems to use R134a refrigerant. If retrofitting, it's important to ensure that the system is properly serviced and compatible with the new refrigerant.
None - a 1995 model year car uses R134a refrigerant, not R12.
Installing R12 refrigerant requires specific equipment and knowledge of refrigerant handling. First, ensure that the system is compatible with R12 and that you're following all local regulations for refrigerant handling. Connect a refrigerant gauge set to the service ports of the system, then use a refrigerant recovery machine to reclaim any existing refrigerant before adding R12. Finally, slowly introduce R12 into the system while monitoring pressure gauges to ensure proper levels are maintained. Always prioritize safety and consider consulting a certified technician for assistance.
Freon R12
Well, R12 is, yes.
R12 Regards.
94 went to r134. but if it is really a 93 chassis, I wouldn't know I think that was the change over year from r12 to r134
