Hi thanks for the advice, we have tried your sugestions and still no joy, the car was back at citroen yesterday so they checked the battery and said it was in good condition, tried again this morning with no electrical items on and engine temp up to operating temperature (my journey to work is about an hour) and it still didn't cut out as it should, before it had the inlet manifold changed it used to cut out as you would expect even on the coldest of days. Anyway thanks again for your help, guess its back to Citroen..... again!
