Hi gang, having a problem with the sunroof, its leaking!! Seems like there is a steel tray at the back of the sunroof and thats badly coroded and a rubber seal has come off and from the back also, tried to put it back on but couldnt see where it was supposed to be put on. See the pics for the bit of steel im talking about. just need some advice on what to do, is this a common problem? can the parts be replaced of do i need a new sunroof etc?
