Many thanks for the reply...I did order one but it's not the right one ...

Your welcome.

That's not the seal that usually leaks on the Discovery sunroof, its the one stuck to the underside of frame that is supposed to tighten onto the roof. The seal is flimsy hence the need to use silicone IMO.

The silicone in this case was there because there was no rubber seal what so ever...excessive would be an understatment..... the seal on the front sun roof is quite narrow and it needs to be as I reckon it sits in the channel( as you see in the jpg where the little flecks of white silicone are) then when the sun roof is closed the glass sits onto the rubber giving a good seal...

Yep thats where that rubber goes, and if its the front all be fine once its in. However as i found cause of the curve of the roof at the rear the rubber curves aswell and leaves a small gap between it and the glass at the rear of the sunroof, and water got in, So a bit of silicon on the top of the rubber fixed that problem for me.

Yes it is the rear one and I did scan it with my eye and can see exactly what you mean indeed there appears to be 2 dips along the back edge.....thanks for tip....

hi all,
after only 6 weeks of having the discovery and repiaring meny lil faults on the poor thing,
i decidied to tackle the leaking sunroof. the easy part was removing the headling, which came off preety easy, including the fabric which now gives me another job blimy,
Before i thought id dismantel the sun roof i decided to pour i bit of water to see were the leak were, and have found it not the roof thats leaking but the seal around the windscreen,
the sunroof leakd very just slightly, and jus a good clean of the seals and rail its totaly leakless, apart for a little surface rust around sunroof (next job)
any ideas on how to repair the windcreen seal?
or should i jus bound with a windscreen sealent?
thanks

No worry buddy

I read this article and carried out the fix by repairing the broken hose fixing above the driver's seat. It has just rained for the first time and the usual internal waterfall has resulted so I will have to sit on plastic bags next time I drive! I suspect that the tubes are blocked but not at the top. Can anyone tell me precisely where they come out under the car front and back please?

They dont. The front ones finish inside the A pillar and are the start of the rotten bottom A pillar syndrome. Landrover have executed a nice double wammy there :d.. Best thing is to replace the complete tube and ensure it sticks out of the bottom of the A pillar.
