Just been doing a bit of a forums search and I might have found the problem, that being the scuttle plate by the windscreen rubber. I'll check this out later, but just wondered since that post in 2011, and other than the water filled sills and dodgy rear windows, has anyone else found cause of rainwater ingress? I found a puddle of water in the passenger side front foot well this morning after heavy rain last night. I actually saw it drip once from under the dash on to the mat too.
