Hi, My wife's very low mileage (27k) car had this problem last year and it was a faulty spring tensioner causing the timing belt to slip. Problem has just returned after leaving the car parked for a week. Will get it fixed and part ex it for a Golf asap. Avoid Peugeot.
i had same problem with my 407(see questions and answers last)someone suggested i give the car a good blast on the motorway for an hour.i did and car runs perfect with more power but still light comes on MOST of the time.
