I have a 2013 500 turbo which experienced the cylinder 4 code, P106B, OIL SUPPLY SOLENOID VALVE SWITCH ON TIME OUT OF RANGE. We've owned it three months and now it's parked 4 hours away in my parent's garage. I've been quoted $3000 to install a new multiair actuator or $4500 for a used engine. I'm eager to find out how you do. Thanks for posting.
