The recommended way to clean the sunroof drains is with some smooth flexible wire type device rather than compressed air. Just in case the pipe is really blocked and pops off at a joint when you pressurise it.

Old broken Speedo drive cable what I use as flexible yet stiff enough to shift blockage

I've cleaned the drains, absolutely no dirt.

However I did find this..

Clutching at straws now...

I've sealed it up there too...

I'll have to wait and see!

Would that cause a leak do ya think?

I was going to ask what it looks like from the other side - but the headlining is still in isn't it? Any chance you could take the interior edging away from the sunroof; carefully ease the headlining down in that corner; and shine a torch or mobile phone camera in there? Might give you a little more confidence if it might/not be leaking there?

The inside of my headling is clearly discoloured at the point of my windscreen leak, but looks pristine everywhere else - which gives me more confidence that I don't have a leaky sunroof (or should I say 'didn't before I took it apart).

If you could see rusty stains on the bottom of the sunroof frame; or any staining on the back of the headlining, you might get some pointers?

Well in today it relatively dry in terms of shit falling out the sky..

So I peeled off the cover and soaked the windscreen and around where the upper trim goes, and there was no water getting in, no reason for it to either as the bonding looked good when I went up there and broke all the clips!!!!!!!!!!!!!!!!!

Ahh!!

Anyway..

It's either the sunroof or the seam sealant under the plastic covers on the roof..

so that's a sigh of relief since the original screen is blemish free!

Nowt annoys me more than a thread without a conclusive fix/resolution..

So here I go!

Something similar happened a few months ago and it was the sunroof frame, so I started there..

.The problem has finally been sussed..

going through the common problems

The windscreen seal is good, I had no reason to believe there was anything wrong with it..
Sunroof drains are clear
The seam sealant on the roof was all intact

So it left my old friend the sunroof frame/glass itself..

The sunroof seal itself is wrapped around the glass frame which in turn is sealed to the glass with a mastic, the steel that makes up the frame is very poorly protected and by design water will find its way under the seal and just sit on the frame between the glass and after years of moisture the frame rusts and swells which breaks the seal between the frame and the glass, the subsequent issue is water finding its way under the seal and on to the inside of the glass/frame which in turn will wick down the glass and on to the headliner..

Upon removal of the seal what I found didn't look too good

Ex Rover 800 parts!

Not only is the frame terminal but the bonding between it and the glass had all but disappeared around the frame, the metal was also very thin even light pressure from my wire brush caused the frame to bend and thus a big gap appeared between it and the glass and as such water was wicking under the seal and onto the inside of the glass which then found its way on to the headliner

enter image description here

The fix for this in an ideal world would be a new frame but since It's a daily I can't remove the roof for any length of time so some silicone will have to do, a thin bead between the glass and the frame is ideal, however if the bead is too thick the seal won't seat properly and the roof won't close. Found that out the hard way... LOL

enter image description here

I used some clamps to hold the seal while the silicone set.

And fixed.

After a few days of heavy rain it is drier than the sahara inside which makes me happy..

As having to toss a cover on it every time I park up becomes very tedious indeed..

Hey - that's encouraging! I still haven't fitted my 'refurbed' sunroof back onto the car - it's just been too cold up here, but we've been above freezing for a few days, so maybe this weekend.

I can see that you looked at this thread anyway, but I think you've highlighted another example of the same sunroof/frame weakness. It might help someone else in future to tie them together.

I took some pictures as I was going along with the refurb but I've yet to bring the thread to a close.

Looking forward to being 'as dry as the Sahara' myself.

Both of mine are leaking at the moment and it’s driving me nuts.

It’s only the drivers side footwell that’s getting wet which is leading me to believe it’s likely to be something around the pollen filter on that side.

Plan for this weekend is to clean one of them up and seal it all up with sikaflex before reassembly.

Check it not O rings to heater matrix if drivers side wet 👍

One of them just had a new heater matrix and the other had the o-rings done recently.

When doing the taste test, it’s definitely fresh water thankfully. On one of them you can see a drip just above the accelerator pedal.

Mine used to do that. it was a mixture of warped pollen filter housing covers and the screw/fixing below

enter image description here

there is a plastic insert IIRC and it wasn't sealing which caused no end of headaches!

I put some sealant around it!

The covers themselves had warped in the middle and even with the OEM gasket they were letting water in, I used silicone.

I used coloured water to try and narrow the issue down...

It did work!
