Question: "I have a leak in my car , the carpets are wet and the car is full of water. Can I claim on the insurance?"
Answer: Highly unlikely... however, if you had a crash and the insurance arranged for repair, or you have a windscreen replaced under windscreen cover, and either of these repairs were done poorly and resulted in a leak, then you would have recourse somewhere. They will usually pay for you to get your car valeted. The valeters will shampoo the carpets and spray around some air freshener, and that just isn't good enough. You can see in Part 2 of this Volvo C70 video.
