Given the wide range of different codes you've got here, my money would be on either a bad battery or bad ECU ground causing the myriad of issues you're seeing.
Versatuner 175bhp map, H&R Wheel Spacers, Red Ambient Lighting, Sony XAV-AX100, Upgraded speakers, Leather Handbrake/Gearlever Gaiters + Armrest, Red Door Piping LED Interior/Exterior Lighting, Exhaust Tips...and about 50kg of sound deadening!

I've had the battery checked today
Cleared all codes left the car just idleing for 20 mins then the light came on sometimes it can take all day driving to get it to come back on then sometimes it's every 5 mins or so
Could it just be one sensor throwing it all out of whack
Any more help would be much appreciated
