Discovered drivers mat wet about 3 weeks ago and whether co incidentally it was at time of awful heavy prolonged spell of wet weather and flooding. Mechanic has secured a grommet type thing that was surrounding an area behind the brake panel - there is possible steering column type thing. Sorry I cant explain it any further. However, having place towels in the area to dry up water, and felt with the grommet secured that this was end of problems. I know that I need to get area dried out and plan to have this done in next day or so. My problem is where is this water coming from? Advice I have got randomly is that it could be coming in from windscreen which I believe had been replaced prior to me purchasing car. Another suggestion was pollen filter? Can anyone else throw any light and if youve had any similar problems? I am taking car to mechanic this week for thorough check over. Its 2015 diesel automatic. Thanks in advance for any assistance.
