ive found a serious wet patch (almost a puddle) in the passenger footwell of my mk6 rs2000 4x4, ive taken out the battery to see if the tray has rusted through but it hasnt. the door rubber seems to be fine, i know the mk6 can suffer from leaky screens but that doesnt seem to be the case here. does anyone have any ideas as to where else it is likely to be coming from? any help would be great as i need to solve this.
