Desperate to solve leak from Sunroof - HELP!

[aureliusmax]

If all else fails, remove the cartridge, and rebuild it with sealant.

After doing this I still had leaks in the form of drips through the overhead console, and with working drains, I'm assuming it's the windshield upper sealant breaking down. At least there's no more pooling water in the passenger well.

Ok well I've poked an inspection camera along the sunroof rails and also up the drain.

It appears clear but I can't work out what's happening at the end of the rail?

So this is the plumber snake coming out the rear drain hole.

Can anyone help interpreting these images? Does anything look wrong?

Ta.

I was never good at that game, can't tell anything. But here's a pic of the rear right corner of the cassette. You can see the hose opening there. In my case that whole black plastic thing area and in front of it for a few cm was completely clogged with Autumn debris

Thank you!

That makes my picture make sense. How is the black drain well section connected to the rails? Could that have come adrift and water leaking around the edges?

I do recall someone saying that was an issue in at least one case.

Ok having a look down the left hand side (Amplifier side) there are what appears to be leaves and debris at the back of the rail where the drain hole is. The hole itself is not blocked as shown by the fibreglass drain unblocker coming out.

How on earth am I to clean the stuff out?

I would recommend using a piece of heavy guage weed trimming line, take the end and make diagonal cuts so the open cuts face away from the close end.
This will make a one sided burr to drag crap out of tight areas.

So after pulling a lot of trim apart and everything out of the left hand boot well I realised that I was missing the seal front the front edge of the rear glass panel! Bloody hell!

I found it stuck to the cross channel drain that goes under the two glass pieces.

Omg!

So from now on leaking sunroof steps are;

Step 1: Make sure you have all the seals in place!






It appears that the shear volume of water going down the channels simply overwhelmed the rear drains to the point it overflowed into the roof lining space and down the D pillars into the rear

So the seal is siliconed back in place and another water test done!

You rippa! No leaks from the roof lining or D pillars!

But wait..... what's this? Water pouring in from tailgate area into the subwoofer enclosure side?

The tail lights are good now....no leaks from those at all.

So I found this.





A loose bolt, the water was coming in very easily and filling up the right well.

So I pulled the bolts out, added silicone to the nut and bolt, reattached and tightened. Another water leak check and no more leaks!

Thanks all,

I hope this thread helps somebody in the future

Nice. That seal was broken off partially for me too. Glad you didn't unbolt anything further.

The one thread that was linked here earlier, the one guy said he covered the whole glass and probably the whole roof with PPF. I think it's a great idea. I'm going to do that for sure. All new seals, clean working roof, still pull fuse 58, clay and polish the roof, and cover the whole thing with film. No water ingress...
