This seems to be a common problem with the 172s.. Water leaking into the spare wheel area. About a year ago, I supposidly had this fixed by the dealer here, but today when i was having the car down at the tyre place for some tyres, it is all wet in there again. Did renault ever acknowledge this problem and issue a technote on it? If so, anyone got a copy that i can show my dealer here in australia.. cheers
