Hi guys and girls, my friend has a 2004 (I think) Lupo and she is complaining of water leaking on passenger side foor well especially in a turn or roundabout and windscreaan steaming up big time. She also claims that it sounds like water moving in a bottle from side to sdie. I have offered to have a look and help. Please let me know if you have any starting point/suggestions. I do have some technical orientation but don't have any experience with this model whatsoever. Many thanks in advance, EJ
