Replace the electric refrigerant shut-off valve. It’s mounted on the A/C lines near the radiator. The internal coil failed common on W222. New valve, clear code, done.

There was an issue with m S550e I think that is hybrid only but i had same issue and required a completely new compressor. 2.5k later I had a new one thankfully I had an extended warranty
