Have solved the noise in my sunroof.
Heres how:
Cleaned the inner part of roof where sunroof meets body. Then ran some 4-6mm draught excluder about 4mm from the upper edge of the cavity that the sunroof fits into, took the car for a spin and got up to around 100mph ( private road
) and hey presto the Pope could say mass in the car now without any interruptions!!!
