I have a series 2 td5 year 2000. bout a month ago i noticed water patches in the top front corners of the ceiling interior. so i removed all the interior decking and could not find problem. I then had to have my windscreen replaced and thought that had solved it, but no it only leaks when stationary ie overnight when it rains.i am sure it is not the windscreen leaking and i have checked the roof rails. could it be from the back? or those small windows at the rear. I am distraught, it is really bugging me, can anyone help?. I have read all previous threads also
