I have taken the car back twice to the dealer for the problem with not much luck.They tell me that the water is dripping from above the fan unit but they can not locate the source of the leak.Now they want me to book the car in again so they can remove the dash and try locate the problem.Due to there workmanship i really don't want them to touch the dash but i don't have much choice.
In regards to removing the dash it can be abitch of a job so you need to refer to a service manual like Gregory's if DIY or a panel beater.
