Hi, I have a 2005 CitrOEn C4. When the headlights are on and the doors are opened a warning buzzer used to go off to basically tell me to turn off the lights. This hasnt worked for the last few months. I left it in for a service and when collecting it they told me that it required a comm for the buzzer that is not working. Cost €350. This sounds steep. I had the same problem on a Renault Megane a few years back and all it required was a switch of some sort on the door. Does it sound like the garage are ripping me off???
