If it's a variable​ valve that always spins, does that mean there would be no shim to ad or remove to adjust the air gap as that's a clutch related part?
I'm probably going to tear into mine today if there's a possibility of me being able to fix it like that, otherwise I'll probably have to bite the bullet and get a new compressor. I know my aux fan and hvac panel are fine and not the problem.
Is therr anyway to clean out the valves in the compressor, like if they're getting stuck and that's why they intermittently work?
On some variable valve compressor, the valve can be replaced. I believe the valve in a BMW with the variable compressor can be replaced. But the refrigerant in the system will have to be recovered before replacing the valve. Unless you have the equipment and knowledge to recover refrigerant from a close system, best to take it into an AC shop.
