I guess this could be one of many things; first port of call the front screen and the various clips that hold the trim on; second is whether it can come in around the door seals??

My doggy aroma was the sunroof and now its as dry as a sea biscuit thanks to Arctic's excellent thread but sadly if you have no SR it must be something else.

:shrug:

I am in the process of adding to this thread the spyhole mod, and the plenum leaf collector with pics as always so they are all in one place on a thread to save new members searching from one post or thread to another.

The first chance i get i will try and get a camera down the plenum chamber with the tube removed and see what lies below :D Arctic.
look forward to a pic of 'what lies beneath'!!

I think this looks to me like a dealer mod on mine then as the tube is absent and I can clearly see the road below. (and I can pretty much hose it and no water comes in anywhere??

Hi John.
Hope you going to do the spyhole mod now it makes it much easier to check also change the pollen filter as it must be soaking with that amount of water in the plenum looks like you have had a lucky escape ;) Arctic

Had my 75 for about 6 weeks now, after reading this thread I thought it was time I checked mine.
It appears that someone has modified my central one - it has a grommet type thing at the top, which looks like the original, but there's no centre in it.
Underneath that, there is what appears to be a length of rubber tube with an inner diameter of 10 - 15mm which goes town to the floor level of the car.
Shine a torch down and I can clearly see the road underneath, it's not blocked & my plenum's bone dry.
Seems like the old girl's had a pretty enthusiastic owner at some point.

Hi John.
Glad that you caught it in time lets hope all the mebers check them and regular at least once a week with the old jack frost about now you will be carring your own giant ice cube if you do not that water will turn a solid block, then if it rains or you decide to wash the car water on top of that will soon reach the ECU :shrug: just not worth it rod and rod again is the name :D Arctic
