Anyone any idea as to what this could be?

Some ideas from this thread

Diagnostic trouble code (DTC) information 1-1-3
Condition
Short-term fuel trim indicates the amount by which basic programmed injection time must be varied to achieve optimum fuel/air mixture. If the control module finds the engine is running lean, short-term fuel trim increases to extend the injection time and restore the mixture to its ideal ratio. If the engine runs so lean that the short-term fuel trim reaches its maximum (upper limit) and stays there for 3 minutes, the system records diagnostic trouble code (DTC) 1-1-3.
Under certain conditions the ignition coil can generate a pulse which interferes with the operation of the engine control module (ECM) which causes diagnostic trouble code(s) (DTC) 113 and/or 112 to be stored and activates the engine malfunction indicator lamp (MIL).
Substitute value
The integrator is set to its central value and adaptation is disabled. When the engine starts, the short-term fuel trim resumes control of the injection time until the diagnostic trouble code (DTC) condition is met once more.
Possible source
- Contact resistance in heated oxygen sensor (HO2S) connections.
- defective heated oxygen sensor (HO2S).
All that said though, if it is running lean that may not be the fault of the oxygen sensor - could be air leak for example

Like exhaust manifold leak? Its had a new lambda sensor in it a couple of weeks ago
I thought that would make it run rich if there was a boost leak?

Yeah i get ya!!
I think iv found my problem now anyway, taking advice from doingitsideways i began spraying round the inlet manifold. Low and behold its sucking in electrical spray around cylinder no.2, it has a shudder everytime i spray!!
Wheres best place to get a new gasket, or can i get a ptfe gasket?
Yay, I was right about something!
Don't stop there though, keep going around EVERY joint, along the length of all vac/boost hoses, intercooler if you can get to it.
You may find a few more tiny leaks that won't be helping.
As for the gasket... Volvo. Every time!
Try FRF Swansea, ask for Simon, mention forum discount and you'll get 10% discount.
Postage prices are reasonable too.
