It looks easy for the 940 but I am not sure about the 940 turbo, as maybe some of the turbo parts are in the way. I'm not sure about that, since there is no documentation on the turbo model vs. the 940 standard model. If you can follow the following instructions, then I would give it a whirl.

you have to check you engine starter (dispositive that is made to turn on your car)

Turbo or non turbo engines are 2.3 liter.

the BOO switch, (Brake On Off) located on or near the brake pedal

I had a issue with my cruse control. Look under the hood. The the wire to the diaphragm for the crues might have popped off the throttle pully!

The code seems to point to the camshft actuator circuit. Namely the Oil Control Valve. Probably needs replacement. I do not know the location on your vehicle. I suggest you ask a mechanic or try to find it online.

Best bet is to talk with the local Volvo service manager..or a skilled mechanic. Normally, I don't think any real service is needed,unless there is a problem. Changing oil every 3K is good..not racing the car (turbo) just as you start up or shut it down is helpful too.
