Whilst cleaning my car at the weekend (I've neglected the interior cleaning for a few weeks) I rather worryingly found a small pool of water in the spare wheel bay which explained the heavy condensation/misting on the rear screen. I've managed to clear the water and dry it out and I've been checking it daily this week especially so after the heavy rain that has plagued the area I live in this week and I have not found any further trace of water intrusion into the boot. I am hoping/Praying (I'm not a religious man) that the water was there as a result of opening the boot in heavy rain or with water built up on the tailgate after a shower. I have noticed that when I lift the boot lid water seems to run off the tailgate and drip down into the boot area and down onto the boot lid hinges. I have checked as best I can the condition of the rubber boot seal, it is firmly in position and doesn't appear to be damaged anywhere. So far I've not found any more water but I can't help but think it may be a leak somewhere and most likely a faulty boot seal but I'll keep monitoring it and see how it goes. I really don;t fancy stripping the boot interior out and then sitting in the car while someone hoses the back of it to see where the water is coming in.
