Hi Folks. I currently own a Volkswagen Polo 02-05 model which is an 05 plate and a 5 door model. I went to get something that I keep in the Spare Wheel compartment located in the boot. When I went in, the Spare Wheel compartment was full of roughly 3 pints full of water. I got rid of it. A few weeks previous, I did notice that the back seat was looking a bit damp but never thought anymore about it. I was therefore wondering if this is perhaps a common problem with this model and vintage of Volkswagen Polo? Your thoughts would be very much appreciated. Many thanks. John G
