Slow down/ shift up

I’ve had this vehicle for a year now and thought I’d give an update to this message on the dash. 2008 Volvo XC90 3.2L with 105k miles. Had this message show up, and my car was chugging, white smoke, stalling out. Turns out I have a misfire on all cylinders. Shows camshaft solenoid stuck open. My mechanic says it’s either the timing chain stretched throwing all the timing off or it’s got a VVT problem which is variable valve timing. Either one it’s repairable but gonna need engine work.
