I have an A4 3.0 Cabriolet. All is well other than the headliner has to start coming away from the main frame. (Stitching line above the drivers head and above the passenger) By the looks of it the stitching has started to come out on the drivers side. Does anyone know of a good way to repair or know of a repairer near Portsmouth. My wife mentioned just sticking a drawing pin in to stop the stitching coming away anymore.
