Knocking sound from E320 panaramic roof

I have a E320 2004 with a full glass panaramic roof. Up till very recently there were no problems. Some months ago a knocking sound when travelling on uneven roads could be heard coming from the roof between the door and roof on the passenger side. I was first advised by local Merc garage that a new roof was required then after much hassle they stripped it down and said there was a loose nut. Three months later the problem has come back. Has anybody else experinced this and if so did you find a solution. I should say the car has only done 65000 miles and the sunroof has rarely been used.
