2.5 turbo code says suction valve stuck. What valve is it referring to
SOURCE: code 1-1-3 volvo 940 turbo
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.

Did you replace hoses to eliminate the codes?? Try checking all the fuses for a start then check for any ignition sparks then try to listen to the fuel pump activation on IGN and STRT as well just try to go step by step and eliinate the different components as you go. Good luck.

take off pipe going to the intercooler from the turbo see if oil is found and clean then other pipe from incooler check it .if oil is found .drain oil in intercooler .you have an oil leak from the turbo this is why you will have light on far left of dash

Sounds like the fuel filter is dirty... When have you replaced it last? Possible that the pump is bad but I would start with the filter.
Turn the Volvo 850 off and allow the engine and its components to cool for 30 minutes.
Open the hood of the Volvo 850 by pressing the hood release button within the vehicle. Locate the PCV valve; the valve is identified as a small rubber valve located on the engine crankcase. You will also notice a small hose sticking out of the end of the valve. If needed, read the Volvo 850 owner's manual for more information.
Disconnect the hose from the valve by pulling the hose out of the valve. The hose will come off the valve with minimal force.
Turn on the engine of the Volvo 850. Place your finger over the hole in the valve where the hose was connected. If you feel a strong suction, the valve is working properly and fine. If you do not feel a strong suction, the valve may be clogged and needs replacing.
Turn off the engine of the Volvo 850. Use needle-nose pliers and grip the valve. Pull the valve off of the crankcase.
Install a new valve by putting the valve in place on the crankcase. Insert the hose into the new PCV valve. Secure the new valve in place by pushing it down until it locks into place. Close the hood of the Volvo; pull up on the hood to ensure the hood is shut properly.
