After 3 months and many visits to the garage I finally got my C4 back in full working order last Thu, and I can honestly say I'm well chuffed!! I've just spent some time reading posts from people who are clearly unhappy with their car and I can sympathise with them. I waited 3 months for a garage to isolate and fix my problems (reminder: it was the climate control and the cruise control) but now that I've got it back I can't complain. And on enquiring what caused the problem, it was in actual fact, nothing to do with citroen. The previous owner has installed high performance speakers and sub and whoever wired it up really messed up. As soon as it was switched on, it fried a lot of the circuit boards. So I was very lucky Citroen carried out the work under warrenty To those people who seem really p****d off with their C4 all I can suggest is stop moaning, sell it and buy into something boring like a Golf or Focus!!! Incidentally I might be selling the 6X9's that he left. They are Infinity Kappa. Keep your eyes on E-bay if your interested.
