All e32s were R12 AC compressors right?

The plot thickens...
Also you should be able to tell by the high and low pressure fittings. R134 are different than r12 so they can't be mixed
Ive got 1990 735 and r12 system :-(
Really really thickening.
I'll have to do a manual inspection in the morning. Thanks everyone.
OK, I'm out. :( Seems my knowledge about E32 AC systems just converged to Zero :)
My 92 735 is r12
I don't know if the compressors are actually different, I do know both systems will work with r134a if you just add adaptors to the service connections. If you are filling up with a different type gas it is always a good idea to change the dryer filter
And I believe that the type of system also depends on which market the car was made for.
If i fill R12 system with r134a it will not damage seal?
No, the main difference is the lubricant. They differ with the gas, but you can use an additive that allows them to mix and be less harsh on the o-rings. My refrigerant guy who works with all kinds of ac systems said that these kinds of problems are rare ☺
Great, thanks for info
In the US the switch from R12 to R134 was in 1994. The last E32 was built in 1994 but I am not sure if the 1994 E32s have R134 they may have waited till the E38s came out.since car are generally built before the model year
