How sure are you that its leaking through the sunroof?
I had a leak above the driver and passenger seats in my renault clio and i found it to be the front windscreen.
The water was getting in when i was both stationary and on the move.
At the top corners of the windscreen there are 2 L shaped covers which seal each corner - For me this is where the water was getting in.
I just decided to seal as much of the windscreen as possible with silicone and also to glue down the covers securly - Did the job for me !
