(T) Sprung a leak!!

My dad got his Bravo in January and last week when he went to the boot after a bit of rain and noticed a bit of water around the parcel shelf but thought it just dripped in when he opened the boot. But on Sunday it rained for a few hours and water is leaking in somewhere from the o/s of the rear. Water seems to be coming from where the seatbelt comes out of the pillar, that kind of area.

He brought it up to the dealer yesterday where they spent an hour pouring water on the rear of the car and sure enough the water started to leak into the car again. So they are going to take the lining off the rear today and investigate whats going on. We were thinking if it was just rubber on the boot lid then it be coming through somewhere near the bootlid but its further in than that..so unsure of what it is!

Was wondering did anyone have problems like this? I know there were recalls in UK for drainage holes in the boot, but they seem to be there, I don't know if it's connected or not!
