Do any of you have a German car using CO2 as a HVAC refrigerant? What are your experiences? Thanks.

Are you sure it's CO2? It would have to operate at really high pressures! That's expensive and likely to leak!

What car is it?

High pressure shouldn't be a problem, fuel pressure on DI engines is higher and they don't leak.
