I thought i'd post a reply to my original answer for help on my fuel light. I booked my Peugeot 207 into local dealer yesterday and they returned the car back to me today with the problem resolved with the fuel light. As it is an 08 plate, it was covered under the warranty. Anyway Peugeot advised they had replaced fuel pump and tank and this had resolved issue. Hope this helps!!
