Hi had a new problem, every time it rains lots if water accumulating in rear passenger foot well behind drivers seat, so far I have replaced the pollen filter, removed battery and seat to clean the drain hole, removed and cleaned the pollen filter housing checked the seal in ok condition, but still evey time it rains water level rising, worst so far was 12 litres in 12 hour period of very heavy rain in Plymouth. Any ideas are anybody else sufferring the same

 

It sounds like your sunroof drain might be the problem.


if you look around here you should find a DIY on fixing it

 

I have this same problem but dont have a sunroof, cant find where its coming from

 

If you don't have a sunroof you might check your rear window seal.
If you have a sunroof I would definitely point to the sunroof drains. There are 4 drains - 1 in each A pillar and one in each C pillar.
