Citroen C21.6 16v - Citroen C3 code 1.6 16v - dunleyc
Good afternoon
This is my first attempt at a post and wondered if anyone can help me, I have just started to hear a constant ticking noise coming from the top end of my c2, also there is a distinct lack of water in the header bottle, can anyone tell me what this is Likely to be?
Any info help would be very much appreciated

Regards Julian
