I've had my 1998 S70 2.5D for almost 2 years now. It was some months later when it rained really hard that I discovered that the 'old lady' leaked. The point from where the rain drops fall into the cabin is lighting console at the top of the window, directly above the auto gear shift. I've tried (re-)sealing the rubber seal at the top of the window, but none or little improvement ... in other words, I'm not sure. Has anyone got any ideas how it might be coming in? I was working for a few months in South Wales when I first discovered it (it seemed to be always raining in the Rhondda!). The amount of rain in the passenger-side (to the left of the driver) footwell was not insignificant. Additionally, is there likely to be some place that might be acting as a reservoir. In all other respects I am very happy with the S70, despite the diesel having done about 145k and sounding a bit like a tractor at startup.
Any help in tracing this annoying leak will be much appreciated.
