You have CEL P0420 (cat below efficiency) .....obviously as it's not there 
You can either have the car remapped (EcuTeK) to remove the CEL and gain a few BHP ...TOP choice
Or you can buy a CEL fix from a number of suppliers which fools the ECU into thinking the rear lambda sensor is sending the correct signal. Scoobyworld do one I think. Usually about 40 quid.

I would DEFINATELY get it remapped, otherwise you could be heading for engine trouble. IMO. It'll set you back around £600-£700 but it's worth it.
Plus you'll get LOADS more power, ~40-60bhp and a shed load of torque.
