Done the paperclip test on my car and got three codes

25 - Injector valve Low voltage
29 - 29 Fuel pump relay Low voltage
71 - Air Temperature Sensor (ATS) (MPi only) High voltage

What do they actually mean and how can I fix the problems? Any help would be much appreciated

injector valve low voltage would suggest you aren't getting power to the injector, and same with the fuel pump relay, and as for air temp sensor it would suggest the sensor is buggered, have you got a multimeter? if so use it to check the voltage at the injector and use the resistance setting to chect across the air temp sensor believe it's supposed to be about 20k? p.s. i presume the car won't start is that right?
