Well here's a surprise water is getting into my boot, but not via the usual suspects. There is a boot liner fitted and the water is getting on TOP of it, so I can rule out rear light seals, waist trim seals and having inspected it there is no leak from the windscreen clips, it becomes worse if the car is parked with the boot downhill (hardly leaks at all with the boot parked uphill) I thought it might be the seal so I replaced it, there is still water on top of the liner after heavy rain, there is no sunroof, so how the heck is it getting in? any ideas?
