Check Engine Light, anyone know what's going on?

Got all these codes, seems like a VANOS issue, there's a rattling sound when I open the hood. I get limp mode and it gets weaker over time. Any ideas? Car is at 116k miles.

Thanks!

Clear them and then when the CEL pops back up, immediately read the codes and see what is starting this chain. Could be VANOS related or it could be something else

I got the attached

I actually I had those exact same VANOS faults recently. Got the 2C58 too which is a response to the VANOS fault.

My thoughts on best COA, would be clean and swap the solenoids. That may solve the problems all on its own. If codes pop back up but error on the exhaust side, it would point to that solenoid that needs to be replaced. If the fault stays on the intake side, you would have to dig a little deeper.

I had my shop clean both VANOS solenoids and swap positions to start. So far the car has been running great so I’m hoping my problem is gone
