Ford Focus Estate car 2006. Water leaking on n/s/r quarter panel above the lamp aperture. Its not the rear lamp seal. The headlining is not marked with water but comes in a fair bit during steady rain. It has been water tested, you can see the water dripping down but where from nobody knows or can see.
check arround the tailgate hinges, we have had a few leak there and goes inside the body panels and leaks further down
