2001 vovlo v7o xc trouble codes p0014 and p1237

DTC P1014 - B Camshaft Position - Timing Over-Advanced or System Performance (Bank 1).
At engine start-up the control module checks that the camshaft is in the correct position in relation to the crankshaft. Diagnostic trouble code (DTC) ECM-62 is stored if the control module detects the camshaft in an incorrect position on start up.

Possible source:
Camshaft cogs incorrectly seated
Incorrectly installed camshaft pulley
Contact resistance in the terminals.

Malfunction indicator lamp (MIL) lit
The engine misfires.

DTC P1237 - Turbo Control Valve
Looks like the turbo is not producing enough boost. Check the waste gate hoses and the waste gate itself to see if its bound up. If the waste gate is working right, I would suspect a bad turbo.

This is an advanced level repair. You may want to have Volvo do the diagnostics on this one. Your code is for low turbo boost pressure. The waste gate is a big silver actuator on the turbo. It has vacuum hoses going to it. See if they are all hooked up. Also see if you can move the lever that the actuator pushes on. If its jammed that may be your problem.

Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa.

Next to the service button is a green triangle with a sorta reverse check mark - does anyone know what this means

That is a "Lambda" symbol.
Volvos "Check engine" lamp.

If this one lits, there is possible that there is some trouble with the oxugene sensor or enginge electronics.

If only lit before the engine starts: All OK.

95 volvo 940 running rough

Have you checked compression on non firing cylinders? Likely has blown head gasket between these two cylinders if located side by side.
