I bought a citroen c4 about 7 months ago, the car still has 13 months warrenty on it. I had it serviced in Jan at my local citroen garage, I felt that it didn’t run quite as well as before it was serviced. About a week ago I heard a very slight tapping noise, yesterday the screen flashed that there was a antipollution problem and the car started loosing power. I took it back to the citroen garage, who now say that the fuel filter is full of dirt and it not covered under warrenty, I normally get my fuel from my local tesco, but it is not unusual if I’m out of the area to pop into anther garage for fuel. The bill looks as though it will be the best part of £1,000, I’m devastated, is there anything else I can do regarding getting this sorted?
