My understanding is that this can be a common issue for this model of Porsche - caused I think, by water seeping down the inside of the external windscreen rubber surround and collecting at the base of the A pillar.
I have just had such corrective work undertaken by a porsche-approved bodyshop (windscreen out and new rubbers fitted; along with several 'hold your breath' moments along the way!) but it appears that water is still flowing down the inside of the rubber surround (on the outside of the car). Surely this will - over time - create the same problem as I've tried to fix? Should not the new surround be 'watertight'?
Does any Forum reader/contributor have experience of such issues and any similar work being undertaken; specifically in relation to the watertightedness of the external rubber surround? Is there a recommended 'fix'?
Many thanks,
John Dymond
PS : as far as I can tell there is no water ingress inside the cabin of the car
