Not an answer as such, but a question - does your Micra have a sunroof? Reason for the question is, after three "old shape" Micras with no problems, our "new shape" Micra 1.4 collects water after every rainfall in the RH (driver's in UK) side footwell - up to a full inch or more! The soft roof lining next to the sunroof is also saturated, so it can't be door or window seals, unless rain has suddenly started going upwards... Any experience of this please anyone - I fear a Nissan Dealer would rub his hands with glee and dismantle the car before telling me it's one of those "untraceable" faults...
