Having experienced a heater matrix go, they fill the passenger foot well first, then after a certain point it starts to fill the drivers side. But before all that you get steam pouring out the vents. Pretty unmistakable. My first 306 used to randomly fill the foot wells with water. Took it to a jet wash once blasted the shit out of everywhere and it was fine. Then one afternoon in the rain, i got in, and splash soak through me shoes lol. Sunroof drain offs or door seals i reckon!
Doesnt even own a 306.
