loss of power?

Hi m8, I have a Stilo on a 52 plate. Had the same problem last year, was told it was many things including the EGR Valve. I spent loads of cash on mine. Now it has happend all over again, this time the car wont turn over and the car is stuck on the driveway.. This happened in the cold weather in Feb and now in this cold spell so dont know if the fault is linked to cold weather or not. If you get yours fixed can you let me know what it is. Cheers
