Hi,   Ive got the same model, Ive had serious boot leaking problem plus 2 inches of rain in the footwell this year.   Because I am out of warrantee Ive had to go to citroen direct.  Similarly Ive heard from alot of people that there is serious probs with the roof and I understand it has been re designed twice in the last 18 months.  I am now waiting for a reply from Citroen on a way forward!
