I have a 630 registered 2005. After a week of being sat on the driveway in heavy rain, I have found that the rear passenger footwell carpet area is soaking wet. I do not have a sun roof and wondered if anyone one else has had a similar problem and can point me in the right direction. Door and window seals pass the hose pipe test with flying colours. A bit stumped what to check next.
Any advice greatly appreciated.
