Hi I have just purchased a used 52 plate Citroen C3 1.4LX. All is well with the car, but I am getting an audible warning of 4-5 beeps everytime I slow down to first gear. The garage I got it from dont know what is causing it and as far as I can tell nothing as actually wrong. I didnt have a drivers manual with the car and have been unable to find any similar problems on line. Does anyone what is causing this audible warning, is it an important warning and if not can it be disabled. As I said, it only occurs when in first gear. Many thanks
