Tracing this water leak, running out of ideas!

I would also suggest you check roof strips (for attaching racks) to make sure they are properly sealed.

I also had leaks, and the biggest appeared because of bad work on replacing windscreen.
Check it, maybe it sits too deep in. There should be no gaps between windscreen and moldings, if you look from outside.

One more thing how to check leaks on windscreen:
-Pour bucket of water on it , all over it. Then take A4 white sheet of paper, and while sitting inside the cabin, push the paper sheet behind the dash where windscreen and dashboard comes together, and all around it. Stick paper in and pull out, in-out, in-out . If somewhere there is a water, You will see immediately, that wet spots appeared on paper

This leak started about 6 months ago and was quite severe flooding the carpet heavily. I thought to have fixed the leak but on and off there have been trickles as per the photo leaking in to the cabin on harsh downpours,

I hope from the above someone can suggest something else for me to look at? My car is a facelift model so i assume the drivers plenum wont need checking as its blocked off? I did jack the car up over the weekend and took the under-tray off, located the drivers plenum drainage tube but it seemed clear...

Thank you to anyone in advance.

The drivers Plenum area can still fill with water. It is usually a one piece trough right across the car but some have a partition in the centre. Any water will normally drain through the passenger drain tube due to road camber but, if it is blocked or restricted then the water would build up until
it tried to drain down the drivers side. You say it seemed clear but did you actually
open the end and poke upwards to see if water came out?

It was only the very first early R75's that had the partition across the bulkhead.

Something else I have learnt tonight. Thanks Bill.

Quick update:

As suggested i took the scuttle trim off again and had another look at the clips and seals. I had to disturb the sealing i had already put in place which was a pain, however i had not sealed the large window clip on the drivers side which was a suggested culprit. Sealed this off over the weekend and had redone all the previous sealing work. I left the cover off the car and awaited the inevitable rain. Came to my car this morning, bone dry Hopefully that is that!

Thank you to everyone who inputted to the thread.

I Google'd it for you and found this - http://www.75ztcommunity.co.uk/rain-...-t5856-20.html - photo 10 shows the large black clip in between the white scuttle clips and photo 13 shows the seal applied around it.

I will of course keep an eye on it but so far so good!
