Hi there, i´m luciano from brazil citroen c5 2.0 gasoline 2002 100.000 km my problem started with a creaky noise (mettalic) without any loose part. then the rear suspension locked at the highest position and the front at the lowest. i´ve changed the pump already and the front is normal, but the rear is at the lowest position now, with no response. i would like to know if anyone has some good idea to help. i am really desperate.
