Must say, I am stunned at how little difference the vario cam seems to make. If as they said, it wasn’t working at all on bank 1-3 when I brought it in, and it’s not working well now, why does the car run so well? I can’t tell the difference. Seems like a lot tech for not much performance.

Well, the solenoid just operates a valve that controls oil flow within the actuator. It still can be totally fine if the actuator is bad, or the oil passages are blocked. It’s not too parsimonious to replace a $500 part without making sure it’s faulty. If you have the solenoid you can easily test it with a battery.
